Add dma_declare_coherent_memory() API
This adds the description and a null prototype.
Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
<jejb@mulgrave.(none)>
Add memory region bitmap implementations
These APIs deal with bitmaps representing contiguous
memory regions. The idea is to set, free and find
a contiguous area.
For ease of implementation (as well as to conform
to the standard requirements), the bitmaps always
return n aligned n length regions. The implementation
is also limited to BITS_PER_LONG contiguous regions.
Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
<jejb@mulgrave.(none)>
Add vmalloc alignment constraints
vmalloc is used by ioremap() to get regions for
remapping I/O space. To feed these regions back
into a __get_free_pages() type memory allocator,
they are expected to have more alignment than
get_vm_area() proves. So add additional alignment
constraints for VM_IOREMAP.
Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
<jejb@mulgrave.(none)>
Add x86 implementation of dma_declare_coherent_memory
This actually implements the API (all except for
DMA_MEMORY_INCLUDES_CHILDREN).
Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
<jejb@mulgrave.(none)>
Convert NCR_Q720 to use dma_declare_coherent_memory
This board makes an ideal example for using the API
since it consists of 4 SCSI I/O processors and a
0.5-2MB block of memory on a single MCA card.

EMU10K1/EMU10K2 driver
Fix Audigy + FX8010 capture (hw:x,2)
This patch fixes capture problems from hw:x,2 on Audigy. It is same as
previous, because it can be applied cleanly against CVS (I tested
version from 23.06.2004) and hope it is still true for current CVS.
I tested 4 channel recrding and it was OK.
hw:x,2 records outputs from FX8010 (not FX buses)
Using 'EFX voices mask' you can set channels what you want record.
use alsactl store to store config
edit this config (set true for needed channel for 'EFX voices mask'
control) - I recorded channels 8,9,14,15 (front and rear output).
use alsactl restore to restore config
Looks like channel count must be power of 2 (1, 2, 4, 8, ...).

PCM Midlevel
snd_pcm_timer_resolution_change():
Right, that function doesn't work well for 44100/1024 in 32 bits -- it
ends up trying to calculate 1e7 * 1024 / 441 and having to divide
both numerator and denominator by 4 (thus losing the rather crucial 1
at the end of 441) before it can do the calculation without overflow.
Attached is a patch against 1.0.5a that gets better results in this
instance, by leaving the denominator alone and instead doubling the
result back up by the same number of times as the multiplier had to
be halved by.

I fixed it, i.e. it works for me:
*No swapping of stereo channels

[PATCH] fix scsi_remove_device locking
The following patch fixes an oops I was seeing on a machine with

The oops was occurring because scsi_remove_device was getting

This resulted in sysfs_remove_link being called with a NULL dentry.

[PATCH] tmscsim: kernel bugzilla bug #2139
> Short: The attached patch fixes the bug-report #2139 from kernel bugzilla.
I wasn't quite convenient with the previous version of the patch, but I
just wanted to get it working at first and get some comments as to whether
the approach (put a workaround vs. blacklisting) is at all valid. Since no
objections arrived, I guess, nobody minds this small trick. So, I am
enclosing a reworked patch, which does essentially the same, but has some
more careful checking, and overall looks saner, than the previous one.

[PATCH] SCSI ips: remove inlines
Trying to compile drivers/scsi/ips.c with gcc 3.4 and
# define inline __inline__ __attribute__((always_inline))
results in the following error:
<-- snip -->
...
CC drivers/scsi/ips.o
drivers/scsi/ips.c: In function `ips_eh_abort':
drivers/scsi/ips.c:490: sorry, unimplemented: inlining failed in call to

make[2]: *** [drivers/scsi/ips.o] Error 1
<-- snip -->
The patch below removes all inlines from ips.c. As a side effect, this
showed that 3 formerly inlined functions are completely unused which are
also removed in the patch.
An alternative approach to removing the inlines would be to keep all
inlines that are _really_ required and reorder the functions in the file
accordingly.

[ADD] Add pci=firmware command line option
This change is specifically needed for the IXP2000 platform. IXP2000
platforms have various PCI devices with large memory space requirements
(~3.5 GB total sometimes) and a banked PCI window that allows for accessing
all 4GB of memory space. The FW configures the devices on the bus in such
a way that standard linux drivers (e100, e1000, ide) can work w/o any changes
and places devices specific to Intel's closed source IXA sdk in regions of
PCI memory space that require using special registers on the IXP. This can
be accomplished in the kernel using a board-specific enumerator or a
lot of fixups, but it is far easier to just accept what the FW has provided.

[PATCH] SCSI dc395x.c: fix inline compile errors
Trying to compile drivers/scsi/dc395x.c in 2.6.8-rc1-mm1 using gcc 3.4
results in compile errors starting with the following:
<-- snip -->
...
CC drivers/scsi/dc395x.o
drivers/scsi/dc395x.c: In function `dc395x_handle_interrupt':
drivers/scsi/dc395x.c:388: sorry, unimplemented: inlining failed in call
to 'enable_msgout_abort': function body not available
drivers/scsi/dc395x.c:1740: sorry, unimplemented: called from here
make[2]: *** [drivers/scsi/dc395x.o] Error 1
<-- snip -->
The patch below moves enable_msgout_abort above the place where it is
called the first time and removes the bogus inline from the prototype of
set_xfer_rate (the function itself isn't marked as inline).
An alternative approach would be to remove the inline from
enable_msgout_abort.

[PATCH] SCSI tmscsim.c: fix inline compile errors
Original Patch From: Adrian Bunk <bunk@fs.tum.de>
I looked at those 3 functions. dc390_EnableMsgOut_Abort is called 5 times
in the code and is 0x30 bytes long (as compiled with 3.3.2), so,
uninlining it, probably, makes most sense. The other 2 functions are
called only ones each and from the interrupt, so, I applied the
"alternative approach" to them - moved above the calling functions.

[PATCH] ibmvscsi driver v1.5.1
Based on comments from hch and jejb, an update to the ibmvscsi
driver patch. Primarily style issues, though the removal of
gratuitous casting lead to some significant refactoring
of functions.
- Moved #include <asm/...> after #include <linux/...>
- removed the map_direct_data and map_indirect_data and moved
the function inline
- Fixed function declaration style issues (static on a line by
itself)
- Removed bogus cast from dma_map_single
- Moved setting of data transfer direction to a single helper
function
- Fixed up some gratuitous casting of types
- Collapsed a couple of other functions inline
- Removed bogus check for NULL from remove
- Removed the "evt_struct_for" routine as being needlessly obfuscatory

[PATCH] Fix double reset in aic7xxx driver
From: Joe Korty <joe.korty@ccur.com>
Fix occasional PCI bus parity errors on the Dell PowerEdge 4600 during
boot.
Symptoms: The LCD display would turn orange and display "PCI SYSTEM E13F5",
and the following message would appear in /var/log/dmesg: "Uhhuh. NMI
received. Dazed and confused, but trying to continue".
By inserting a PCI card with a PDC20268 IDE controller and attaching to
that a Sony DRU-510A DVD RW burner with an unloaded tray, the failure can
be made to happen on every boot.
Cause: The aic7xxx driver was resetting the onboard AIC7891 SCSI controller
while waiting for a previous reset to complete. This second reset confuses
the controller causing it to put bad data onto the PCI bus.
This is a backport of a RedHat 2.4.21-15.ELsmp fix. A letter discussing
this problem, or one very close to it, may be found at:

- The buffer reservation / preallocation in snd-page-alloc module is

[PATCH] ipr: Use cancel all instead of abort task
Currently, ABORT_TASK does not work properly on ipr adapters. It results in
timeouts and eh ends up getting escalated to eh_host_reset to recover.
The adapters are supposed to be fixed to properly handle this at some
point in the future, but until that updated microcode is available,
we need to send a cancel all to the device instead.

AUTOSENSE bug in NCR5380.c
From: Kenn Humborg <kenn@linux.ie>
round line 2470 in NCR5380.c, if a command fails, and AUTOSENSE is on,
the current command is converted into a REQUEST_SENSE command and
put at the top of the request queue. Part of this setup, is setting
up cmd->SCp to point at the sense_buffer, so that the received sense
data goes straight into the sense buffer.
Around line 1730, NCR5380_select() calls initialize_SCp() which ends
up clobbering cmd->SCp, and the sense data get written into the
original request buffer.
This is what happens if cmd->use_sg = 0. I haven't looked at what
happens if use_sg is non-zero, but I expect the effect will be the same.

Signed-off-by: Tony Luck <tony.luck@intel.com>
<ak@suse.de>
[IA64] various issues in the IA64 swiotlb code
The biggest change is better overflow handling, partly ported from the AMD64
IOMMU code. This is important for some 3d drivers who make use of this and can
map a lot of memory.
First it increases the default memory usage of swiotlb to 64MB.
This was the value used in production systems in 2.4 (e.g. in SLES8) and the default
was far too small. Note this is only allocated when the swiotlb is needed.
pci_map_single will not panic anymore on an overflow. Instead it returns
a pointer to a scratch area and allows the caller to check using
dma_mapping_error(). It still panics when the overflow buffer is exceeded.
dma_mapping_error support is implemented.
pci_map_sg will never panic now, but just return 0. Near all callers
of it seem to have proper error checking for this (IDE will even handle
it without erroring out)
The handling of passing a NULL device is improved, previously it would
never map in this case. i386 and other architectures assume NULL means a 4GB
limit instead. This code does this now too.
I added support for swiotlb=force for easier testing.

[PATCH] Allow TCQ depth to be lowered properly
Ran into a couple small issues with the patch. First,
blk_queue_resize_tags wasn't getting exported, so I sent Jens a patch to
fix this, which he has now sent upstream. Second, the comment above
blk_queue_resize_tags says the queue_lock must be held when calling this
routine. Attached is an updated patch that grabs the lock. Other than
that, it looks good.

[PATCH] fix for Domain Validation hang on some devices with sym_2
There's a bad hang where the driver locks the system solid trying to do
domain validation with certain devices. The one I've managed to
reproduce it with is a Quantum Atlas.
What happens is that setting the offset to zero is an async negotiation
message. However, the driver still seems to have DT set (which is
illegal). Most devices just reject this as stupid, but the Quantum
seems to try to obey it and hangs the bus.
The simple fix is to reset all PPR options when the offset is set to
zero.

fix sym2 negotiation
The problems with domain validation were just the tip of the iceberg in
the sym2 driver. Most of its problems seem to come from an overly
complex set of negotiating rules, which I've swept away with this patch.
I also removed the ability to set parameters in the on-board bios and
have the driver respect them. (this hasn't worked for a while in 2.6
because after the driver sets them, Domain Validation resets them
again).
Finally, there was a really nasty bug where the driver negotiates
improperly when turning off DT clocking. If you simply turn it off, the
driver originally fell back to using the old WDTR/SDTR method of
negotiation. However, since it thought the bus was already wide, it
only emitted a SDTR, which causes the device to reset from wide to
narrow. Hence the driver thinks the device is wide and the device
thinks it is narrow => boom.
I redid the negotiation to predicate PPR messages on whether the device
claims support for them or not.

[PATCH] sched: fix timeslice calculations for HZ=1000.
The main benefit is that with the default HZ=1000 nice +19 tasks now get 5
msecs of timeslices, so the ratio of CPU use is linear. (nice 0 task gets
20 times more CPU time than a nice 19 task. Prior this change the ratio
was 1:10)
another effect is that nice 0 tasks now get a round 100 msecs of timeslices
(as intended), instead of 102 msecs.
here's a table of old/new timeslice values, for HZ=1000 and 100:
HZ=1000 ( HZ=100 )
old new ( old new )
nice -20: 200 200 ( 200 200 )

[PATCH] sched: limit cpuspan of node scheduler domains
This patch limits the cpu span of each node's scheduler domain to prevent
balancing across too many cpus. The cpus included in a node's domain are
determined by the SD_NODES_PER_DOMAIN define and the arch specific
sched_domain_node_span routine if ARCH_HAS_SCHED_DOMAIN is defined. If
ARCH_HAS_SCHED_DOMAIN is not defined, behavior is unchanged--all possible
cpus will be included in each node's scheduling domain. Currently, only
ia64 provides an arch specific sched_domain_node_span routine.
From: Jesse Barnes <jbarnes@engr.sgi.com>
This patch adds some more NUMA specific logic to the creation of scheduler
domains. Domains spanning all CPUs in a large system are too large to
schedule across efficiently, leading to livelocks and inordinate amounts of
time being spent in scheduler routines. With this patch applied, the node
scheduling domains for NUMA platforms will only contain a specified number
of nearby CPUs, based on the value of SD_NODES_PER_DOMAIN. It also allows
arches to override SD_NODE_INIT, which sets the domain scheduling parameters
for each node's domain. This is necessary especially for large systems.
Possible future directions:
o multilevel node hierarchy (e.g. node domains could contain 4 nodes
worth of CPUs, supernode domains could contain 32 nodes worth, etc. each
with their own SD_NODE_INIT values)
o more tweaking of SD_NODE_INIT values for good load balancing vs.
overhead tradeoffs

allow us to build sched_domains for PPC64 with generic code in

[PATCH] scheduler statistics
It adds lots of CPU scheduler stats in /proc/pid/stat. They are described in
the new Documentation//sched-stats.txt
We were carrying this patch offline for some time, but as there's still
considerable ongoing work in this area, and as the new stats are a
configuration option, I think it's best that this capability be in the base
kernel.
Nick removed a fair amount of statistics that he wasn't using. The full patch
gathers more information. In particular, his patch doesn't include the code
to measure the latency between the time a process is made runnable and the
time it hits a processor which will be key to measuring interactivity changes.
He passed his changes back to me and I got finished merging his changes with
the current statistics patches just before OLS. I believe this is largely a
superset of the patch you grabbed and should port relatively easily too.

The version below is for 2.6.8-rc2-mm2 without the staircase code and has
been compiled cleanly but not yet run.
From: Ingo Molnar <mingo@elte.hu>
this code needs a couple of cleanups before it can go into mainline:
fs/proc/array.c, fs/proc/base.c, fs/proc/proc_misc.c:
- moved the new /proc/<PID>/stat fields to /proc/<PID>/schedstat,
because the new fields break older procps. It's cleaner this way
anyway. This moving of fields necessiated a bump to version 10.
Documentation/sched-stats.txt:
- updated sched-stats.txt for version 10
- wake_up_forked_thread() => wake_up_new_task()
- updated the per-process field description
Kconfig:
- removed the default y and made the option dependent on DEBUG_KERNEL.
This is really for scheduler analysis, normal users dont need the
overhead.
include/linux/sched.h:
- moved the definitions into kernel/sched.c - this fixes UP compilation
and is cleaner.
- also moved the sched-domain definitions to sched.c - now that the
sched-domains internals are not exposed to architectures this is
doable. It's also necessary due to the previous change.
kernel/fork.c:
- moved the ->sched_info init to sched_fork() where it belongs.
kernel/sched.c:
- wake_up_forked_thread() -> wake_up_new_task(), wuft_cnt -> wunt_cnt,
wuft_moved -> wunt_moved.
- wunt_cnt and wunt_moved were defined by never updated - added the
missing code to wake_up_new_task().
- whitespace/style police
- removed whitespace changes done to code not related to schedstats -
i'll send a separate patch for these (and more).

this is a property of the base scheduler as well.
We can do a nonlinear timeslice distribution trivially - the attached
patch implements the following timeslice distribution ontop of
2.6.8-rc3-mm1:

[PATCH] sched: smt fixes
while looking at HT scheduler bugreports and boot failures i discovered a
bad assumption in most of the HT scheduling code: that resched_task() can
be called without holding the task's runqueue.
This is most definitely not valid - doing it without locking can lead to
the task on that CPU exiting, and this CPU corrupting the (ex-) task_info
struct. It can also lead to HT-wakeup races with task switching on that
other CPU. (this_CPU marking the wrong task on that_CPU as need_resched -
resulting in e.g. idle wakeups not working.)
The attached patch against fixes it all up. Changes:
- resched_task() needs to touch the task so the runqueue lock of that CPU
must be held: resched_task() now enforces this rule.
- wake_priority_sleeper() was called without holding the runqueue lock.
- wake_sleeping_dependent() needs to hold the runqueue locks of all
siblings (2 typically). Effects of this ripples back to schedule() as
well - in the non-SMT case it gets compiled out so it's fine.
- dependent_sleeper() needs the runqueue locks too - and it's slightly
harder because it wants to know the 'next task' info which might change
during the lock-drop/reacquire. Ripple effect on schedule() => compiled
out on non-SMT so fine.
- resched_task() was disabling preemption for no good reason - all paths
that called this function had either a spinlock held or irqs disabled.
Compiled & booted on x86 SMP and UP, with and without SMT. Booted the
SMT kernel on a real SMP+HT box as well. (Unpatched kernel wouldn't even
boot with the resched_task() assert in place.)

[PATCH] i386 virtual memory layout rework
Rework the i386 mm layout to allow applications to allocate more virtual
memory, and larger contiguous chunks.
- the patch is compatible with existing architectures that either make
use of HAVE_ARCH_UNMAPPED_AREA or use the default mmap() allocator - there
is no change in behavior.
- 64-bit architectures can use the same mechanism to clean up 32-bit
compatibility layouts: by defining HAVE_ARCH_PICK_MMAP_LAYOUT and
providing a arch_pick_mmap_layout() function - which can then decide
between various mmap() layout functions.
- I also introduced a new personality bit (ADDR_COMPAT_LAYOUT) to signal
older binaries that dont have PT_GNU_STACK. x86 uses this to revert back
to the stock layout. I also changed x86 to not clear the personality bits
upon exec(), like x86-64 already does.
- once every architecture that uses HAVE_ARCH_UNMAPPED_AREA has defined
its arch_pick_mmap_layout() function, we can get rid of
HAVE_ARCH_UNMAPPED_AREA altogether, as a final cleanup.
the new layout generation function (__get_unmapped_area()) got significant
testing in FC1/2, so i'm pretty confident it's robust.
Compiles & boots fine on an 'old' and on a 'new' x86 distro as well.
The two known breakages were:
http://www.redhatconfig.com/msg/67248.html
[ 'cyzload' third-party utility broke. ]
http://www.zipworld.com/au/~akpm/dde.tar.gz
[ your editor broke :-) ]
both were caused by application bugs that did:
int ret = malloc();
if (ret <= 0)
failure;
such bugs are easy to spot if they happen, and if it happens it's possible
to work it around immediately without having to change the binary, via the
setarch patch.
No other application has been found to be affected, and this particular
change got pretty wide coverage already over RHEL3 and exec-shield, it's in
use for more than a year.
The setarch utility can be used to trigger the compatibility layout on
x86, the following version has been patched to take the `-L' option:
http://people.redhat.com/mingo/flexible-mmap/setarch-1.4-...
"setarch -L i386 <command>" will run the command with the old layout.
From: Hugh Dickins <hugh@veritas.com>
The problem is in the flexible mmap patch: arch_get_unmapped_area_topdown
is liable to give your mmap vm_start above TASK_SIZE with vm_end wrapped;
which is confusing, and ends up as that BUG_ON(mm->map_count).
The patch below stops that behaviour, but it's not the full solution:
wilson_mmap_test -s 1000 then simply cannot allocate memory for the large
mmap, whereas it works fine non-top-down.
I think it's wrong to interpret a large or rlim_infinite stack rlimit as
an inviolable request to reserve that much for the stack: it makes much less
VM available than bottom up, not what was intended. Perhaps top down should
go bottom up (instead of belly up) when it fails - but I'd probably better
leave that to Ingo.
Or perhaps the default should place stack below text (as WLI suggested and
ELF intended, with its text defaulting to 0x08048000, small progs sharing
page table between stack and text and data); with a further personality for
those needing bigger stack.
From: Ingo Molnar <mingo@elte.hu>
- fall back to the bottom-up layout if the stack can grow unlimited (if
the stack ulimit has been set to RLIM_INFINITY)
- try the bottom-up allocator if the top-down allocator fails - this can
utilize the hole between the true bottom of the stack and its ulimit, as a
last-resort effort.

[PATCH] uml: Fixes "fixdep.c" to support arch/um/include/uml-config.h.
You probably saw that if you change one config option, even if
linux/autoconf.h (which is included by everything) changes, the kernel is
smart enough not to recompile everything. But with UML this no more holds.
Why? Because, as you see in this patch, fixdep avoids making anything depend
onto linux/autoconf.h *explicitly*, but nobody taught him to do the same for
arch/um/include/uml-config.h. So apply this patch. Do not say "I don't want
to change the generic Kbuild for one arch": this cannot hurt. It's a bugfix
for us, a no-op for others.
Note: with this patch, fixdep will still add a dependency from a file
containing UML_CONFIG_BYE onto CONFIG_BYE. Since someone could think that
fixdep should grep for [^A-Z_]CONFIG_ rather than simply for CONFIG_, I've
added a comment that ask *not to fix* this "bug".

[PATCH] New x86-64 merge
This fixes various issues in the previous update, in particular
a kernel without CONFIG_GART_IOMMU should boot now again,
The kernel discoverys PCI BUS<->CPU affinity on AMD systems
now. It is so far used by dma_alloc_coherent to allocate memory
Experimental patches to add this to sysfs exist, but they're not
included yet. On systems with no memory on a CPU this information may
be wrong.
It has a new experimental CONFIG_UNORDERED_IO option. When enabled
it uses write combining for stores to device iomemory mapping. This
may give better performance with some device drivers, but has a slight
risk of breaking drivers (in general if a driver works on ia64,ppc64,sparc64
it should also work). Based on some discussions with Grant Grundler.
It requires the driver to use memory barriers properly. I would be interested
in feedback on any performance changes you're seeing. For a production system I
would recommend to keep it turned off(although I run it on all my systems and
haven't run into any problems yet)
ACPI and Centrino speedstep is enabled now for Nocona systems.
The IOMMU code does lazy merging by default now, which should be safe
and may increase performance on block IO. It also avoids SAC force by default
now.
The machine check code has been improved again, hopefully it is good
now. It will log now machine check events from before the last reset.
And various other fixes.

[PATCH] don't pass mem_map into init functions
When using CONFIG_NONLINEAR, a zone's mem_map isn't contiguous, and isn't
allocated in the same place. This means that nonlinear doesn't really have
a mem_map[] to pass into free_area_init_node() or memmap_init_zone() which
makes any sense.
So, this patch removes the 'struct page *mem_map' argument to both of
those functions. All non-NUMA architectures just pass a NULL in there,
which is ignored. The solution on the NUMA arches is to pass the mem_map in
via the pgdat, which works just fine.
To replace the removed arguments, a call to pfn_to_page(node_start_pfn) is
made. This is valid because all of the pfn_to_page() implementations rely
only on the pgdats, which are already set up at this time. Plus, the
pfn_to_page() method should work for any future nonlinear-type code.
Finally, the patch creates a function: node_alloc_mem_map(), which I plan
to effectively #ifdef out for nonlinear at some future date.

[PATCH] AIO: retry infrastructure fixes and enhancements
From: Daniel McNeil <daniel@osdl.org>
From: Chris Mason <mason@suse.com>
AIO: retry infrastructure fixes and enhancements
Reorganises, comments and fixes the AIO retry logic. Fixes
and enhancements include:
- Split iocb setup and execution in io_submit
(also fixes io_submit error reporting)
- Use aio workqueue instead of keventd for retries
- Default high level retry methods
- Subtle use_mm/unuse_mm fix
- Code commenting
- Fix aio process hang on EINVAL (Daniel McNeil)
- Hold the context lock across unuse_mm
- Acquire task_lock in use_mm()
- Allow fops to override the retry method with their own
- Elevated ref count for AIO retries (Daniel McNeil)
- set_fs needed when calling use_mm
- Flush workqueue on __put_ioctx (Chris Mason)
- Fix io_cancel to work with retries (Chris Mason)
- Read-immediate option for socket/pipe retry support
Note on default high-level retry methods support
================================================
High-level retry methods allows an AIO request to be executed as a series of
non-blocking iterations, where each iteration retries the remaining part of
the request from where the last iteration left off, by reissuing the
corresponding AIO fop routine with modified arguments representing the
remaining I/O. The retries are "kicked" via the AIO waitqueue callback
aio_wake_function() which replaces the default wait queue entry used for
blocking waits.
The high level retry infrastructure is responsible for running the
iterations in the mm context (address space) of the caller, and ensures that
only one retry instance is active at a given time, thus relieving the fops
themselves from having to deal with potential races of that sort.

[PATCH] AIO: Splice runlist for fairness across io contexts
This patch tries be a little fairer across multiple io contexts in handling
retries, helping make sure progress happens uniformly across different io
contexts (especially if they are acting on independent queues).
It splices the ioctx runlist before processing it in __aio_run_iocbs. If
new iocbs get added to the ctx in meantime, it queues a fresh workqueue
entry instead of handling them righaway, so that other ioctxs' retries get
a chance to be processed before the newer entries in the queue.
This might make a difference in a situation where retries are getting
queued very fast on one ioctx, while the workqueue entry for another ioctx
is stuck behind it. I've only seen this occasionally earlier and can't
recreate it consistently, but may be worth including anyway.

[PATCH] AIO: workqueue context switch reduction
From: Chris Mason
I compared the 2.6 pipetest results with the 2.4 suse kernel, and 2.6 was
roughly 40% slower. During the pipetest run, 2.6 generates ~600,000
context switches per second while 2.4 generates 30 or so.
aio-context-switch (attached) has a few changes that reduces our context
switch rate, and bring performance back up to 2.4 levels. These have only
really been tested against pipetest, they might make other workloads worse.
The basic theory behind the patch is that it is better for the userland
process to call run_iocbs than it is to schedule away and let the worker
thread do it.
1) on io_submit, use run_iocbs instead of run_iocb
2) on io_getevents, call run_iocbs if no events were available.
3) don't let two procs call run_iocbs for the same context at the same
time. They just end up bouncing on spinlocks.
The first three optimizations got me down to 360,000 context switches per
second, and they help build a little structure to allow optimization #4,
which uses queue_delayed_work(HZ/10) instead of queue_work.
That brings down the number of context switches to 2.4 levels.
Adds aio_run_all_iocbs so that normal processes can run all the pending
retries on the run list. This allows worker threads to keep using list
splicing, but regular procs get to run the list until it stays empty. The
end result should be less work for the worker threads.
I was able to trigger short stalls (1sec) with aio-stress, and with the
current patch they are gone. Could be wishful thinking on my part though,
please let me know how this works for you.

[PATCH] rmaplock: PageAnon in mapping
First of a batch of five patches to eliminate rmap's page_map_lock, replace
its trylocking by spinlocking, and use anon_vma to speed up swapoff.
Patches updated from the originals against 2.6.7-mm7: nothing new so I won't
spam the list, but including Manfred's SLAB_DESTROY_BY_RCU fixes, and omitting
the unuse_process mmap_sem fix already in 2.6.8-rc3.
This patch:
Replace the PG_anon page->flags bit by setting the lower bit of the pointer in
page->mapping when it's anon_vma: PAGE_MAPPING_ANON bit.
We're about to eliminate the locking which kept the flags and mapping in
synch: it's much easier to work on a local copy of page->mapping, than worry
about whether flags and mapping are in synch (though I imagine it could be
done, at greater cost, with some barriers).

[PATCH] rmaplock: kill page_map_lock
The pte_chains rmap used pte_chain_lock (bit_spin_lock on PG_chainlock) to
lock its pte_chains. We kept this (as page_map_lock: bit_spin_lock on
PG_maplock) when we moved to objrmap. But the file objrmap locks its vma tree
with mapping->i_mmap_lock, and the anon objrmap locks its vma list with
anon_vma->lock: so isn't the page_map_lock superfluous?
Pretty much, yes. The mapcount was protected by it, and needs to become an
atomic: starting at -1 like page _count, so nr_mapped can be tracked precisely
up and down. The last page_remove_rmap can't clear anon page mapping any
more, because of races with page_add_rmap; from which some BUG_ONs must go for
the same reason, but they've served their purpose.
vmscan decisions are naturally racy, little change there beyond removing
page_map_lock/unlock. But to stabilize the file-backed page->mapping against
truncation while acquiring i_mmap_lock, page_referenced_file now needs page
lock to be held even for refill_inactive_zone. There's a similar issue in
acquiring anon_vma->lock, where page lock doesn't help: which this patch
pretends to handle, but actually it needs the next.
Roughly 10% cut off lmbench fork numbers on my 2*HT*P4. Must confess my
testing failed to show the races even while they were knowingly exposed: would
benefit from testing on racier equipment.

[PATCH] rmaplock: SLAB_DESTROY_BY_RCU
With page_map_lock gone, how to stabilize page->mapping's anon_vma while
acquiring anon_vma->lock in page_referenced_anon and try_to_unmap_anon?
The page cannot actually be freed (vmscan holds reference), but however much
we check page_mapped (which guarantees that anon_vma is in use - or would
guarantee that if we added suitable barriers), there's no locking against page
becoming unmapped the instant after, then anon_vma freed.
It's okay to take anon_vma->lock after it's freed, so long as it remains a
struct anon_vma (its list would become empty, or perhaps reused for an
unrelated anon_vma: but no problem since we always check that the page located
is the right one); but corruption if that memory gets reused for some other
purpose.
This is not unique: it's liable to be problem whenever the kernel tries to
approach a structure obliquely. It's generally solved with an atomic
reference count; but one advantage of anon_vma over anonmm is that it does not
have such a count, and it would be a backward step to add one.
Therefore... implement SLAB_DESTROY_BY_RCU flag, to guarantee that such a
kmem_cache_alloc'ed structure cannot get freed to other use while the
rcu_read_lock is held i.e. preempt disabled; and use that for anon_vma.
Fix concerns raised by Manfred: this flag is incompatible with poisoning and
destructor, and kmem_cache_destroy needs to synchronize_kernel.
I hope SLAB_DESTROY_BY_RCU may be useful elsewhere; but though it's safe for
little anon_vma, I'd be reluctant to use it on any caches whose immediate

[PATCH] rmaplock: mm lock ordering
With page_map_lock out of the way, there's no need for page_referenced and
try_to_unmap to use trylocks - provided we switch anon_vma->lock and
mm->page_table_lock around in anon_vma_prepare. Though I suppose it's
possible that we'll find that vmscan makes better progress with trylocks than
spinning - we're free to choose trylocks again if so.
Try to update the mm lock ordering documentation in filemap.c. But I still
find it confusing, and I've no idea of where to stop. So add an mm lock
ordering list I can understand to rmap.c.

[PATCH] rmaplock: swapoff use anon_vma
Swapoff can make good use of a page's anon_vma and index, while it's still
left in swapcache, or once it's brought back in and the first pte mapped back:
unuse_vma go directly to just one page of only those vmas with the same
anon_vma. And unuse_process can skip any vmas without an anon_vma (extending
the hugetlb check: hugetlb vmas have no anon_vma).
This just hacks in on top of the existing procedure, still going through all
the vmas of all the mms in mmlist. A more elegant procedure might replace
mmlist by a list of anon_vmas: but that would be more work to implement, with
apparently more overhead in the common paths.

[PATCH] x86 bitops.h commentary on instruction reordering
Back when we were discussing the need for a memory barrier in sync_page(),
it came to me (thanks Andrea!) that the bit operations can be perfectly
reordered on architectures other than x86.
I think the commentary on i386 bitops.h is misleading, its worth to note
that that these operations are not guaranteed not to be reordered on
different architectures.
clear_bit() already does that:
* clear_bit() is atomic and may not be reordered. However, it does
* not contain a memory barrier, so if it is used for locking purposes,
* you should call smp_mb__before_clear_bit() and/or smp_mb__after_clear_bit()
* in order to ensure changes are visible on other processors.

accumulate alarmingly (until memory pressure finally frees them), and are
just a hindrance to any in-memory filesystem. simple_lookup set d_op to
arrange for negative dentries to be deleted immediately.

[PATCH] vm: alloc_pages watermark fixes
Previously the ->protection[] logic was broken. It was difficult to follow
and basically didn't use the asynch reclaim watermarks (pages_min,
pages_low, pages_high) properly.
Now use ->protection *only* for lower-zone protection. So the allocator
now explicitly uses the ->pages_low, ->pages_min watermarks and adds
->protection on top of that, instead of trying to use ->protection for
everything.
Pages are allocated down to (->pages_low + ->protection), once this is
reached, kswapd the background reclaim is started; after this, we can
allocate down to (->pages_min + ->protection) without blocking; the memory
below pages_min is reserved for __GFP_HIGH and PF_MEMALLOC allocations.
kswapd attempts to reclaim memory until ->pages_high is reached.

[PATCH] improve speed of freeing bootmem
Attached is a patch that greatly improves the speed of freeing boot memory.
On ia64 machines with 2GB or more memory (I didn't test with less, but I
can't imagine there being a problem), the speed improvement is about 75%
for the function free_all_bootmem_core. This translates to savings on the
order of 1 minute / TB of memory during boot time. That number comes from
testing on a machine with 512GB, and extrapolating based on profiling of an
unpatched 4TB machine. For 4 and 8 TB machines, the time spent in this
function is about 1 minutes/TB, which is painful especially given that
there is no indication of what is going on put to the console (this issue
to possibly be addressed later).
The basic idea is to free higher order pages instead of going through every
single one. Also, some unnecessary atomic operations are done away with
and replaced with non-atomic equivalents, and prefetching is done where it
helps the most. For a more in-depth discusion of this patch, please see
the linux-ia64 archives (topic is "free bootmem feedback patch").
The patch is originally Tony Luck's, and I added some further optimizations
(non-atomic ops improvements and prefetching).

[PATCH] x86 PAE swapspace expansion

transparently removes that limitation by using more of the space available
in PAE's wider ptes for swap ptes.
While this is obviously not likely to be used directly, it is important
from the standpoint of strict non-overcommit, where the swapspace must be
potentially usable in order to be reserved for non-overcommit. There are
workloads with Committed_AS of over 256GB on ia32 PAE wanting strict

[PATCH] hugetlb: permit executable mappings
During the kernel summit, some discussion was had about the support
requirements for a userspace program loader that loads executables into
hugetlb on behalf of a major application (Oracle). In order to support
this in a robust fashion, the cleanup of the hugetlb must be robust in the
presence of disorderly termination of the programs (e.g. kill -9). Hence,
the cleanup semantics are those of System V shared memory, but Linux'
System V shared memory needs one critical extension for this use:
executability.
The following microscopic patch enables this major application to provide

fs/smbfs/inode.c: In function `smb_fill_super':
fs/smbfs/inode.c:563: warning: comparison is always false due to limited range of data type
Unfortunately, this patch uses the notorious "gcc warning suppression by
obfuscation" technique.
What seems to be going on is that the uid and gid convert macros in
include/linux/highuid.h:
#define __convert_uid(size, uid) \
(size >= sizeof(uid) ? (uid) : high2lowuid(uid))
only call high2lowuid in the case of trying to put a bigger (32 bit, say)
uid/gid in a smaller (16 bit, in this case) word. Gcc is smart enough to see
that the comparison in high2lowuid() macro is silly if called with a 16 bit
source uid, but not smart enough to understand from the __convert_uid() logic
that this is exactly the case that high2lowuid() won't be called.
So replace the logical "<" operator with the bit op "&~". This obfuscates
things enough to shut gcc up.
Only build the half-dozen files that use SET_UID/SET_GID, on arch i386 and
ia64. Only the file fs/smbfs/inode.c showed the warning, both arch's, and
this patch fixed both. Untested further, past staring at the code long enough

This safely obtains the transaction request data during write(), allocates
a page for it and stores it there. The data is returned to the caller for
potential further processing, which then makes it available for the next
read() call via simple_transaction_set(). See the selinuxfs and nfsctl
code for examples of use.

- Reduce size of qstr by 8 bytes, placing int hash and int len together.
We gain a further 4 byte saving when qstr is used in struct dentry
since qstr goes from 24 to 16 bytes and the next member (d_lru)
requires 8 byte alignment (which means 4 bytes of padding).
- Move d_mounted to the end, since char d_iname[] only requires 1 byte
alignment. This reduces struct dentry by another 4 bytes.
With these changes the number of objects we can fit into a 4kB slab
goes from 16 to 17 on ppc64.

[PATCH] remove cacheline alignment from inode slabs
Most of the inode slabs are cacheline aligned. This can waste a fair
amount of memory, especially on architectures with large cacheline sizes
(eg 128 bytes).
Alignment has a few advantages. It prevents 2 cpus from accessing 2 data
structures in the same cacheline. Since struct inodes are well over a
cacheline and there are so many of them, there is little chance we will hit
this problem if we remove the alignment.
Alignment also ensures the maximum amount of the data structure is in the
same cacheline (instead of straddling 2 for example). The large size of
struct inode reduces this advantage.
With this patch the inode_cache slab goes from 640 bytes to 544 bytes, and
the number that fits in a 4kB slab goes from 6 to 7 on ppc64. A number of
other inode slabs also see improvements.

resembled TD entries sufficiently closely to fool the hardware.

[CORRECTNESS] Fixes the inode not getting ctime updated when an xattr is

[DATA] Fixes an issue with dcache hash colliding names in the filesystem
root caused by the d_compare to hide .reiserfs_priv. The bug
can only occur in the filesystem root, which is why we haven't
seen many (any, outside of the suse bugzilla, afaik) reports on

[PATCH] Reduce SELinux kernel memory use on 64-bit systems
The patch below reduces kernel memory used by SELinux policy rules by about
37% on 64-bit systems. This is because the size of struct avtab_node is 40
bytes on 64-bit, and defaults to a size-64 slab.
Creating a slab cache specifically for these structs saves considerable
amounts of kernel memory on 64-bit systems with large rulesets. 'Strict'
policy has over 300k rules, while 'targeted' policy has around 3k rules.
Here's the slabtop output with 64 and 40 byte sized slabs to show the
memory savings, for strict policy:
303475 303447 99% 0.06K 4975 61 19900K avtab_node
303456 303447 99% 0.04K 3161 96 12644K avtab_node
Also, there are 57% more objects per slab.

[PATCH] fix bio_uncopy_user() mem leak
When using bounce buffers for SG_IO commands with unaligned buffers in
blk_rq_map_user(), we should free the pages from blk_rq_unmap_user() which
calls bio_uncopy_user() for the non-BIO_USER_MAPPED case. That function
failed to free the pages for write requests.
So we leaked pages and you machine would go OOM. Rebooting helped ;-)
This bug was triggered by writing audio CDs (but not on data CDs), as the
audio frames are not aligned well (2352 bytes), so the user pages don't just
get mapped.
Bug was reported by Mathias Homan and debugged by Chris Mason + me. (Jens
is away.)

[PATCH] /proc/PID/cmdline truncates arguments early
We received a bug report that /proc/PID/cmdline only shows argv[0] if the
total length of all arguments exceeds PAGE_SIZE. The problem is that
proc_pid_cmdline checks for the presence of a NUL byte at the end of the
args list, and assumes that the application did a setproctitle if there's
any other character.
OTOH proc_pid_cmdline will read just the first PAGE_SIZE worth of arguments
at most, and if you have more arguments, it's quite likely that there won't
be a NUL byte at offset PAGE_SIZE-1.
The attached patch fixes this.

- in write() you update mtime and _a_time instead of ctime as expected,

The patch below fixes an interesting oddity we're seeing with fedora core
development (where we recently started using udev heavily); basically right
now filelock_init() is a module_init(), eg runs late. However that breaks
down because there are earlier /sbin/hotplug callouts, which with udev, do
locking operations. When that happens the kernel oopses because the slabs
for file locks aren't initialized yet.
Solution: initialize this way early. It's only a kmem_cache_create after
all, so can happen early.

[PATCH] USB OTG: ohci reset updates (2/5)
Generic OTG and reset support for OTG.
- Declare and use a start_hnp() board-specific procedure. The OMAP
implementation will come separately, it can't yet be configured.
- When OTG is configured, implement the usb_bus_start_enum() hook;
that just starts a root port reset.
- When some task (usually khubd) resets a root port, make sure it takes
the full 50 msec. The OHCI reset timer is in hardware, and the host
may need to issue multiple resets to guard against concurrent resume.
- For backward compatibility, don't kick in the new 50 msec logic unless
it could be needed: without CONFIG_USB_SUSPEND, nothing will suspend
so nothing could resume. Which is good, at least until we start to
measure how long a reset takes ... it seems chip-specific.

[PATCH] USB OTG: usbcore enumeration (3/5)
Teach usbcore how to enumerate OTG devices and perform HNP:
- CONFIG_USB_OTG is a boolean; it selects CONFIG_USB_SUSPEND.
Boards with a Mini-AB connector should offer it as a config
option; no other hardware could support OTG.
- Before resetting a port, make sure it's not still suspended.
(For example, after an HNP role switch.)
- When an OTG A-Host enumerates a dual-role device, set the
appropriate device feature: B_HNP_ENABLE if it's connected
to the OTG port, otherwise A_ALT_HNP_SUPPORT.
- When an OTG B-Host enumerates a dual-role device, don't
bother debouncing ... the power session is stable already,
the A-Host already debounced.
- The OTG "Targeted Peripheral List" lives in a product-customized
"otg_whitelist.h" header.
- CONFIG_USB_OTG_WHITELIST lets developers choose to ignore whitelist
failures, so unsupported devices can be configured anyway.
- If the whitelist check fails, immediately suspend the device.
* For dual-role devices, that triggers HNP so the other device
can try to act as host.
* For peripheral-only devices, that conserves power ... but not
quite as much as turning off power on that port, which should
eventually be done with OTG ports (and all other ports that
support SRP).
The whitelist logic tries to make use of the existing usb_device_id
logic, but since the interface info isn't available that early it's
a bit awkward use information anywhere outside the device descriptor.

[PATCH] USB: isp1301_omap driver (OTG core)
This adds the isp1301_omap driver, supporting USB OTG on OMAP systems.
The driver tightly couples two different chunks of hardware, which are
used to implement the OTG protocols:
- The Philips ISP1301 OTG transceiver (an I2C device) senses voltage
levels and sources VBUS current in the A-Device roles.
- OMAP's OTG controller handles lots of OTG transitions, and
tells the transceiver what to do.
The driver implements the abstract "otg_transceiver" API, since it's got to
talk to both the host controller (OHCI on current OMAPs) and the peripheral
controller (omap_udc) while hiding a variety of implementation details. It
should be easy to tweak to work on other OMAP boards using the isp1301 chip;
OMAP boards with other transceivers, or non-OMAP boards using isp1301, will
probably find things to learn from.
Note that this also supports two non-OTG modes, with the OTG controller
disabled; very handy for debugging just the host side USB stack, or just the
peripheral side USB stack.

The idea is simple. None of the callers of skb_checksum are passing it
skb's which are shared. They may be cloned however. But the application
checksum is always in the skb header so there is no need to linearise it.
Supposing all these assumptions are correct, then we can avoid the overhead
of skb_copy() and get away with pskb_expand_head().
If the assumption is wrong, we will find out because
pskb_expand_head() will BUG() if skb_shared() is true.

[PATCH] ppc64: better handling of H_ENTER failures
This changes the hash insertion routines to return an error instead of
calling panic() when HV refuses to insert a HPTE (the hypervisor call to
set up a hashtable PTE is H_ENTER).
The error is now propagated upstream, and either bad_page_fault() is
called (kernel mode) or a SIGBUS signal is forced (user mode). Some
other panic() cases are also turned into BUG_ON.
Overall, this should provide us with better debugging data if the
problem happens, and avoids errors from userland mapping /dev/mem and
trying to use forbidden IOs (XFree ?) to bring the whole kernel down.

[ARM PATCH] 2046/1: fix nwfpe for double arithmetic on big-endian platforms
Patch from Lennert Buytenhek
Hi,
I need the patch below (against 2.6.8-rc1-ds1) to make nwfpe properly
emulate arithmetic with doubles on a big endian ARM platform.
From reading the mailing list archives and from helpful comments I've
received from people on this list, I gather that this has come up in
the past, but it appears that Russell King was never really convinced
as to why this patch is needed. I think I understand what's going on,
and will try to explain.
On little endian ARM, the double value 1.0 looks like this when stored
in memory in FPA word ordering:
bytes: 0x00 0x00 0xf0 0x3f 0x00 0x00 0x00 0x00
u32s: 0x3ff00000 0x00000000
u64: 0x000000003ff00000
On big endian, it looks like this:
bytes: 0x3f 0xf0 0x00 0x00 0x00 0x00 0x00 0x00
u32s: 0x3ff00000 0x00000000
u64: 0x3ff0000000000000
It appears to be this way because once upon a time, somebody decided
that the sub-words of a double will use native endian word ordering
within themselves, but the two separate words will always be stored
with the most significant one first. God knows why they did it this
way, but they did.
Anyway. The key observation is that nwfpe internally stores double
values in the type 'float64', which is basically just a typedef for
unsigned long long. It never accesses 'float64's on the byte level
by casting pointers around or anything like that, it just uses direct
u64 arithmetic primitives (add, shift, or, and) for float64
manipulations and that's it.
So. For little endian platforms, 1.0 looks like:
0x00 0x00 0xf0 0x3f 0x00 0x00 0x00 0x00
But since nwfpe treats it as a u64, it wants it to look like:
0x00 0x00 0x00 0x00 0x00 0x00 0xf0 0x3f
So, that's why the current code swaps the words around when getting
doubles from userspace and putting them back (see fpa11_cpdt.c,
loadDouble and storeDouble.)
On big endian, 1.0 looks like:
0x3f 0xf0 0x00 0x00 0x00 0x00 0x00 0x00
Since nwfpe treats it as a u64, it wants it to look like:
0x3f 0xf0 0x00 0x00 0x00 0x00 0x00 0x00
Hey! That's exactly the same. So in this case, it shouldn't be
swapping the halves around. However, it currently does that swapping
unconditionally, and that's why floating point emulation messes up.
This is how I understand things -- hope it makes sense to other people
too.
cheers,
Lennert

[ARM PATCH] 2047/1: disable NWFPE_XP on big endian
Patch from Lennert Buytenhek
Hi,
gcc doesn't understand 80-bit floating point on the ARM currently,
according to the kernel's Kconfig docs, but it would seem that the
current extended double emulation code is broken for big endian
platforms.
So, this patch disables NWFPE_XP on big endian architectures, until
someone comes round and fixes it.
cheers,
Lennert

[PATCH] USB: add omap_udc driver
This patch adds a UDC driver for OMAP, which should work on most

driver supports all USB transfer types (including ISO), has limited
DMA support, and seems to work with all gadget drivers, both to
Linux hosts and to MS-Windows ones.
One reason this UDC is particularly interesting is that recent OMAP
processors all support "USB On-The-Go" (OTG) ... and this driver
supports it on at least "H2-like" boards.
Another reason is that the UDC is very flexible and fully featured;
gadget drivers can allocate fifo space to endpoints in the way that's
most convenient for the application.

Basically, in function efi_memmap_walk, md->num_pages might be decreased
if mem_limit is set, and then at the next time when efi_memmap_walk is
called, trim_top might trim the md again because of IA64_GRANULE_SIZE
alignment, then another md which is beyond mem_limit at the beginning
will be chosen, and its physical page number is larger than max_pfn. Then,
a BUG check is triggered.

[IA64] contig.c: Function find_bootmap_location has 2 bugs.
Firstly, if it's done successfully, it should return -1 instead of 1
because its caller, efi_memmap_walk, will end when find_bootmap_location
returns a value smaller than 0.
Secondly, statement "free_start = PAGE_ALIGN(rsvd_region[i].end)" should
been moved forward. free_start needs to be initialized for every loop
iteration. Current implementation is buggy where initialization is
skipped if range_end <= range_start. Skipping initializing will leads
to overlapping bootmap with one of the rsvd_regions and subsequently
kernel hang at boot time.

[PATCH] I2C: rename in0_ref to cpu0_vid
This patch changes all the i2c chip drivers and documentation to use the
name "cpu0_vid" instead of "in0_ref". The name "in0_ref" was an error in
the first place as motherboard manufacturers may fail to follow the chip
manufacturer's recommendation about which "in" channel to use for VCore
monitoring.
The new name leaves room for chips able to monitor more than 1 vid
value, such as the LM93 and, to a lesser extent, the PC87360 family (all
by National Semiconductor). These chips are typically designed for
dual-CPU motherboards.
This breaks the interface (obviously) so libsensors has been updated to
support both names.

[PATCH] signal handling race fix
The problem:
In arch/i386/signal.c, in the do_signal() function, it calls
get_signal_to_deliver() which returns the signal number to deliver (along
with siginfo). get_signal_to_deliver() grabs and releases the lock, so
the signal handler lock is not held in do_signal(). Then the do_signal()
calls handle_signal(), which uses the signal number to extract the
sa_handler, etc.
Since no lock is held, it seems like another thread with the same
signal handler set can come in and call sigaction(), it can change
sa_handler between the call to get_signal_to_deliver() and fetching the
value of sa_handler. If the sigaction() call set it to SIG_IGN, SIG_DFL,
or some other fundamental change, that bad things can happen.
The patch:
You have to get the sigaction information that will be delivered while
holding sighand->siglock in get_signal_to_deliver().
In 2.4, it can be fixed per-arch and requires no change to the
arch-independent code because the arch fetches the signal with
dequeue_signal() and does all the checking.
The test app:
The program below has three threads that share signal handlers. Thread
1 changes the signal handler for a signal from a handler to SIG_IGN and
back. Thread 0 sends signals to thread 3, which just receives them.
What I believe is happening is that thread 1 changes the signal handler
in the process of thread 3 receiving the signal, between the time that
thread 3 fetches the signal info using get_signal_to_deliver() and
actually delivers the signal with handle_signal().
Although the program is obvously an extreme case, it seems like any
time you set the handler value of a signal to SIG_IGN or SIG_DFL, you can
have this happen. Changing signal attributes might also cause problems,
although I am not so sure about that.
(akpm: this test app segv'd on SMP within milliseconds for me)

[PATCH] signal-race fixes for s390
Update s30 for the signal race fix
From: Mikael Pettersson <mikpe@csd.uu.se>
The signal-race-fixes patch in 2.6.8-rc2-mm1 appears to be a bit broken on
s390.
When forcing a SIGSEGV the old code updated "*ka", where ka was a pointer
to current's k_sigaction for SIGSEGV. Now "ka_copy" points to a copy of
that structure, so assigning "*ka_copy" doesn't do what we want. Instead do
the assignment via current->... just like i386 and x86_64 do.
Furthermore, the SA_ONESHOT handling wasn't deleted. That is now handled
by generic code in the kernel.

it gets called three places and isn't in the critical path.
As a side effect, it will cause a smaller window scale for many people
since the default tcp_rmem fits in a win_scale of 2. This is allows for
finer grain windows (good), but may mask some of the problems with bad

[PATCH] md: fix problems with checksum handling in MD superblocks.
md currently uses csum_partial to calculate checksums for superblocks.
However this function is not consistent across all architectures. Some
(i386) to a 32bit csum. Some (alpha) do a 16 bit csum. This makes it hard
for userspace to keep up.
So we provide a generic routine (that does exactly what the i386
csum_partial does) and:
- When setting the csum, use csum_partial so that old kernels will still
recognise the superblock
- When checking the csum, allow either csum_partial or the new generic
code to provide the right csum. This allows user-space to just use the
common code and always work.
Also modify the csum for version-1 superblock (which currently aren't being
used) to always user a predictable checksum algorithm.

[PATCH] Hotplug CPU vs TASK_ZOMBIEs: The Sequel to Hotplug CPU vs TASK_DEAD
release_task can sleep. Sleeping allows a CPU to go down underneath you.
release_task removes you from the tasklist, so you don't get migrated off the
CPU: BUG() in sched.c.
In last week's episode, our dashing hero (Ingo Molnar) solved this for
self-reaping tasks by grabbing the hotplug cpu lock to prevent this.
However, in an unexpected twist, the problem remains for tasks whose
parents call release_task on them: the zombies are off the task list, and
lurk on the dead CPU.
Fortunately, the comedic sidekick (Rusty Russell) has an answer: let's make
the hotplug callback walk the runqueue of the dead CPU as well, taking care
of the zombies.
1) Restore exit.c to its former form. The comment is incorrect: sched.c
checks PF_DEAD, not the state, to decide to do the final
put_task_struct(), and it does it for all tasks, self-reaping or no.
2) Implement migrate_dead_tasks() in the sched.c hotplug CPU callback.
3) Rename migrate_all_tasks() to migrate_live_tasks().

[PATCH] dnotify + autofs may create signal/restart syscall loop
I saw a recent bug report that showed when a process set up a dnotify against
the autofs root and then attempted an access(2) call inside the autofs
namespace on a mount that would fail, it would create a signal/restart loop.
The cause is that the autofs code checks to see if any signals are pending
after it waits on a response from the autofs daemon. If it finds any, it
assumes that autofs_wait was interrupted, and that it should return
-ERESTARTNOINTR. The problem with this is that a signal_pending(current)
check will return true if *any* signals were received, not just if a signal
that interrupted the wait was received. autofs_wait explicitly blocks all
signals except for SIGKILL, SIGQUIT, and SIGINT before calling
interruptible_sleep_on.
The effect is that if a dnotify is set against the autofs root, when the
autofs daemon creates the directory, a dnotify event will be sent to the
originating process. Since the code in autofs_root_lookup doesn't check to
see what signals are actually pending, it bails early, telling the caller to
try again. The loop goes on forever until interrupted via one of the actual
interrupting signals.
The following patch makes both autofs_root_lookup and autofs4_root_lookup
verify that one of its defined "shutdown" signals are pending before bailing
out early. Any other signal should be delivered later, as expected. It
doesn't matter if the signal occured outside of the sleep in autofs_wait. The
calling process will either go away or try again.

[PATCH] fix MT reparenting when thread group leader dies
When the initial thread in a multi-threaded program dies (the thread group
leader), its child processes are wrongly orphaned, and thereafter when
other threads die their child processes are also orphaned even though live
threads remain in the parent process that can call wait. I have a small
(under 100 lines), POSIX-compliant test program that demonstrates this
using -lpthread (NPTL) if anyone is interested in seeing it.
The bug is that forget_original_parent moves children to the dead parent's
group leader if it's alive, but if not it orphans them. I've changed it so
it instead reparents children to any other live thread in the dead parent's
group (not even preferring the group leader). Children go to init only if
there are no live threads in the parent's group at all. These are the
correct semantics for fork children of POSIX threads.
The second part of the change is to do the CLONE_PARENT behavior always for
CLONE_THREAD, i.e. make sure that each new thread's parent link points to
the real parent of the process and never another thread in its own group.
Without this, when the group leader dies leaving a sole live thread in the
group, forget_original_parent will try to reparent that thread to itself
because it's a child of the dying group leader. Rather handling this case
specially to reparent to the group leader's parent instead, it's more
efficient just to make sure that noone ever has a parent link to inside his
own thread group. Now the reparenting work never needs to be done for
threads created in the same group when their creator thread dies. The only
change from losing the who-created-whom information is when you look at
"PPid:" in /proc/PID/task/TID/status. For purposes of all direct system
calls, it was already as if CLONE_THREAD threads had the parent of the
group leader. (POSIX provides no way to keep track of which thread created
which other thread with pthread_create.)

[PATCH] parport: NetMOS 9805 interface
Add support for netmos devices to the parallel port driver.
NetMOS 9805 support is already in the kernel, this patch adds the support for
the missing 9735,9855,9755 and 9715 chips.
And another remark: The 9735 and 9835 seem to be chips with serial *and*
parallel interfaces, so I suppose they are already claimed somewhere in the
serial driver. I don't know whether this causes any problems. I'm sorry that
I can't test, I've only a 9805 here. Any idea how these "dual" chips have to
be handled by the kernel?

[PATCH] Fix copying of unaligned data across user/kernel boundary
32 bit compatibility code sometimes needs to copy unaligned data across
kernel/user boundary and currently there is no architecture independent API
to do it.
(1) Introduce new APIs __{get,put}_user_unaligned. These APIs are
necessary because the optimal way to copy unaligned data across
kernel/user boundary is different on different architectures.
Some architectures don't even care about alignment.
On some __put_user is faster than __copy_to_user for small sizes.
(2) Optimize __{get,put}_user_unaligned for ia64, x86-64, s390, ppc64.
(3) Fix compat_filldir64() which is broken on big-endian machines

[PATCH] HVCS hotplug fixes
Here is an HVCS (drivers/char/hvcs.c) patch which fixes the hvcs driver
problems with hotplugged vty-server adapters. The current driver handles
the adapter index assignment improperly so after a number of device
removals and insertions the driver could no longer map a tty->index to a
vty-server properly and tty_open() attempts would fail. This patch solves
this problem by always assigning the lowest available index to the new
adapters and returning an index to the list when the adapter is removed.
changelog:
drivers/char/hvcs.c
===================
-Added hvcs_index_list to manage the lowest available index.
-Added four helper functions to manage the list, which include the
creation and destruction of the list, the get'ing of the lowest index,
and the returning of an index.
-Moved free_irq() outside of the hvcs_final_close() function in order to
get it out of the spinlock.
-Rearranged hvcs_close() to accomodate the previous change.
-Removed local CLC_LENGTH define and used HVCS_CLC_LENGTH from
arch/ppc64/hvcserver.h instead.
-Cleaned up some printks and did some house keeping on the changelog.
Documentation/powerpc/hvcs.txt
==============================
-Added information on sysfs 'index' attribute added in previous hvcs
patch.
-Added Q & A section on how to find the proper dev node for a newly
added adapter.
I think this is the last of the HVCS patches for a while, as all of my
oustanding issues have been dealt with.

When I moved sparc64 over to HZ==1000 this added some

things like udelay(1) due to the order of multiplies
and shifts.
Fix this, and move it out to arch/sparc64/lib/delay.c
so it is easier to tinker with this in the future and
also to optimize away one of the multiplies for the
constant delay case just like other platforms do.

Both were broken 18 months ago in 2.5.63 as a side-effect of locking fixes.

[PATCH] ide: do hwif spin up for all platforms
From: Alan Cox <alan@redhat.com>
This was put in for PPC specifically and defined in the 2.4 tree to be
paranoid about breaking stuff. The actual wait for hwif spin up is however
perfectly correct for all drives. In the normal PC case the PC BIOS has done
this but with other embedded boxes and with things like LinuxBIOS it may not
have done. Thus it should always be done.

Some interfaces (notably PCMCIA ones) don't decode the master/slave select so

This checks for the model/serial matching but also knows about non ATA drives
ide=noprobe and a Maxtor problem that was found in Andrew's testing of an

From: Laurent <laurent@gobio2.net>

To sum up, when my card is in 100Mb mode, I have poor throughput but in
10Mb, all seems normal.
After some tests, it seems these results was due to a misdetection of the
PHY device. mii-tool reports :
product info: vendor 08:00:17, model 3 rev 0
and after some search on the web, I found it's a NS DP83847 which is very

[PATCH] Fix DMA boundary overflow bug
We seem to have found an overflow problem in libata-core.c.
We were trying to DMA to the address range 0xffff8000-0xffffbfff.
In the original version of the code, given that address and
count (0xffff8000 and 0x4000), the variable "boundary" would be
set to 0, causing len to be set to 0x8000 (which is greater than
sg_len). Then at the bottom of the loop, sg_len would be set
to 0xffffc000 (0x4000 - 0x8000), which would then cause the
loop never to terminate (until much of memory was scribbled
over or the kernel died).
The code below should be functionally identical, but not be
subject to the same overflow problem (boundary needs to be a
u33).

[IPV4/IPV6]: Fix fragment creation.
We have two problem in ipv4 and ipv6 wrt. to
fragmentation on output. Both of which result
in fragmentation when it is really not needed.
When fragmenting both ipv4 and ipv6 need to make
the post IP-header portion of the packet have a
length of modulo 8. This means that if the PMTU
is not a multiple of 8 after the IP header size
is subtracted, we will fragment for full sized
frames for the modulo 8 bytes.
Furthermore, IPV6 subtracts out space for the
fragmentation header it must add, making unnecessary
fragmentation even more likely.
We still need to handle ip*_append_page() and that
will happen in a followup fix.

misses on SMP and may be especially useful in aiding debugging elusive
races and problems on live systems. More elaborate dynamic tracing tools
such as DProbes can be built over the kprobes interface.

To place a probe on __blockdev_direct_IO:
static int probe_handler(struct kprobe *p, struct pt_regs *)
{
... whatever ...
}
struct kprobe kp = {
.addr = __blockdev_direct_IO,

[PATCH] Jumper Probes to provide function arguments
A special kprobe type which can be placed on function entry points, and
employs a simple mirroring principle to allow seamless access to the
arguments of a function being probed. The probe handler routine should
have the same prototype as the function being probed. Currently
implemented for x86.
The way it works is that when the probe is hit, the breakpoint handler
simply irets to the probe handler's eip while retaining register and stack
state corresponding to the function entry. After it is done, the probe
handler calls jprobe_return() which traps again to restore processor state
and switch back to the probed function. Linus noted correctly at KS that
we need to be careful as gcc assumes that the callee owns arguments. We
save and restore enough stack bytes to cover argument space.
Sample Usage:
static int jip_queue_xmit(struct sk_buff *skb, int ipfragok)
{
... whatever ...
jprobe_return();
return 0;
}
struct jprobe jp = {
{.addr = (kprobe_opcode_t *) ip_queue_xmit},
.entry = (kprobe_opcode_t *) jip_queue_xmit
};
register_jprobe(&jp);

[PATCH] hugetlbfs private mappings
Hugetlbfs silently coerce private mappings of hugetlb files into shared
ones. So private writable mapping has MAP_SHARED semantics. I think, such
mappings should be disallowed.
First, such behavior allows open hugetlbfs file O_RDONLY, and overwrite it
via mmap(PROT_READ|PROT_WRITE, MAP_PRIVATE), so it is security bug.
Second, private writable mmap() should fail just because kernel does not
support this.
I belisve, it is ok to allow private readonly hugetlb mappings,
sys_mprotect() does not work with hugetlb vmas.
There is another problem. Hugetlb mapping is always prefaulted, pages
allocated at mmap() time. So even readonly mapping allows to enlarge the
size of the hugetlbfs file, and steal huge pages without appropriative
permissions.

Just over 33 seconds. Better.
From: Arnd Bergmann <arnd@arndb.de>
I noticed that only i386 and x86-64 are currently using a high resolution
timer source when adding randomness. Since many architectures have a
working get_cycles() implementation, it seems rather straightforward to use
that.
Has this been discussed before, or can anyone comment on the implementation
below?
This patch attempts to take into account the size of cycles_t, which is
either 32 or 64 bits wide but independent of the architecture's word size.
The behavior should be nearly identical to the old one on i386, x86-64 and
all architectures without a time stamp counter, while finding more entropy
on the other architectures.

[PATCH] waitid system call
This patch adds a new system call `waitid'. This is a new POSIX call that
subsumes the rest of the wait* family and can do some things the older
calls cannot. A minor addition is the ability to select what kinds of
status to check for with a mask of independent bits, so you can wait for
just stops and not terminations, for example. A more significant
improvement is the WNOWAIT flag, which allows for polling child status
without reaping. This interface fills in a siginfo_t with the same details
that a SIGCHLD for the status change has; some of that info (e.g. si_uid)
is not available via wait4 or other calls.
I've added a new system call that has the parameter conventions of the
POSIX function because that seems like the cleanest thing. This patch
includes the actual system call table additions for i386 and x86-64; other
architectures will need to assign the system call number, and 64-bit ones
may need to implement 32-bit compat support for it as I did for x86-64.
The new features could instead be provided by some new kludge inventions in
the wait4 system call interface (that's what BSD did). If kludges are
preferable to adding a system call, I can work up something different.
I added a struct rusage field si_rusage to siginfo_t in the SIGCHLD case
(this does not affect the size or layout of the struct). This is not part
of the POSIX interface, but it makes it so that `waitid' subsumes all the
functionality of `wait4'. Future kernel ABIs (new arch's or whatnot) can
have only the `waitid' system call and the rest of the wait* family
including wait3 and wait4 can be implemented in user space using waitid.
There is nothing in user space as yet that would make use of the new field.
Most of the new functionality is implemented purely in the waitid system
call itself. POSIX also provides for the WCONTINUED flag to report when a
child process had been stopped by job control and then resumed with
SIGCONT. Corresponding to this, a SIGCHLD is now generated when a child
resumes (unless SA_NOCLDSTOP is set), with the value CLD_CONTINUED in
siginfo_t.si_code. To implement this, some additional bookkeeping is
required in the signal code handling job control stops.
The motivation for this work is to make it possible to implement the POSIX
semantics of the `waitid' function in glibc completely and correctly. If
changing either the system call interface used to accomplish that, or any
details of the kernel implementation work, would improve the chances of
getting this incorporated, I am more than happy to work through any issues.

[PATCH] fix rusage semantics
This patch changes the rusage bookkeeping and the semantics of the
getrusage and times calls in a couple of ways.
The first change is in the c* fields counting dead child processes. POSIX
requires that children that have died be counted in these fields when they
are reaped by a wait* call, and that if they are never reaped (e.g.
because of ignoring SIGCHLD, or exitting yourself first) then they are
never counted. These were counted in release_task for all threads. I've
changed it so they are counted in wait_task_zombie, i.e. exactly when
being reaped.
POSIX also specifies for RUSAGE_CHILDREN that the report include the reaped
child processes of the calling process, i.e. whole thread group in Linux,
not just ones forked by the calling thread. POSIX specifies tms_c[us]time
fields in the times call the same way. I've moved the c* fields that
contain this information into signal_struct, where the single set of
counters accumulates data from any thread in the group that calls wait*.
Finally, POSIX specifies getrusage and times as returning cumulative totals
for the whole process (aka thread group), not just the calling thread.
I've added fields in signal_struct to accumulate the stats of detached
threads as they die. The process stats are the sums of these records plus
the stats of remaining each live/zombie thread. The times and getrusage
calls, and the internal uses for filling in wait4 results and siginfo_t,
now iterate over the threads in the thread group and sum up their stats
along with the stats recorded for threads already dead and gone.
I added a new value RUSAGE_GROUP (-3) for the getrusage system call rather
than changing the behavior of the old RUSAGE_SELF (0). POSIX specifies
RUSAGE_SELF to mean all threads, so the glibc getrusage call will just
translate it to RUSAGE_GROUP for new kernels. I did this thinking that
someone somewhere might want the old behavior with an old glibc and a new
kernel (it is only different if they are using CLONE_THREAD anyway).
However, I've changed the times system call to conform to POSIX as well and
did not provide any backward compatibility there. In that case there is
nothing easy like a parameter value to use, it would have to be a new
system call number. That seems pretty pointless. Given that, I wonder if
it is worth bothering to preserve the compatible RUSAGE_SELF behavior by
introducing RUSAGE_GROUP instead of just changing RUSAGE_SELF's meaning.
Comments?
I've done some basic testing on x86 and x86-64, and all the numbers come
out right after these fixes. (I have a test program that shows a few

pidhash_init is called before mem_init which is where x86-64 sets up max_pfn.
nr_kernel_pages is setup by paging_init, called from setup_arch, which is also

So export nr_kernel_pages, nr_all_pages. Use nr_kernel_pages when sizing the

Use hlists for the PID hashes. This halves the memory footprint of these
hashes. No benchmarks, but I think this is a worthy improvement because
the hashes are something that would be likely to have significant portions
loaded into the cache of every CPU on some workloads.
This comes at the "expense" of
1. reintroducing the memory prefetch into the hash traversal loop;
2. adding new pids to the head of the list instead of the tail. I
suspect that if this was a big problem then the hash isn't sized
well or could benefit from moving hot entries to the head.
Also, account for all the pid hashes when reporting hash memory usage.

[PATCH] Amiga partition reading fix
I have a large archive of files stored on Amiga volumes. Many of these
volumes are on Fujitsu magneto-optical disks with 2k sector size. The
existing partitioning code cannot properly read them since it appears the
OS automatically deblocks the large sectors into logical 512 byte sectors,
something AmigaDOS never did. I arranged the partitioning code to handle
this situation.
Second I have some rather strange test case disks, including my largest
storage partition, that have somewhat unusual partition values. As such I
needed additional information in addition to the first and last block
number information. AmigaDOS reserves N blocks, with N greater than or
equal to 1 and less than the size of the partition, for some boot time
information and signatures. I have some partitions that use other than the
usual value of 2.
There is one more "fix" that could be put in if someone needs it. Another
value in the "Rigid Disk Blocks" description of a partition is a "PreAlloc"
value. It defines a number of blocks at the end of the disk that are not
considered to be a real part of the partition. This was "important" in the
days of 20 meg and 40 meg hard disks. It is hardly important and not used
on modern drives without special user intervention.
This partitioning information is known correct. I wrote the low level
portion of the hard disk partitioning code for AmigaDOS 3.5 and 3.9. I am
also responsible for one of the more frequently used partitioning tools,
RDPrepX, before that.

[PATCH] interrupt driven hvc_console as vio device
This is an hvc_console patch which provides driver and ppc64 architecture
fixes to enable the hvc_console driver to register itself as a vio device
with the vio bus, provide hotplug add/remove for vty adapters, and act as
an interrupt driven driver on Power-5 hardware or remain as a polling
driver on Power-4 hardware.
arch/ppc64/kernel/hvconsole.c
=============================
- Changed hvc_get_chars() and hvc_put_chars() api to take vtermno rather
than index number.
- Added hvc_find_vtys() function which walks the bus looking for
vterm/vty devices to callback to the hvc_console driver. This provides
console output functionality prior to early console init (pre mem init
and pre device probe).
include/asm-ppc64/hvconsole.h
=============================
- Changed hvc_get_chars() and hvc_put_chars() api to take vtermno rather
than index number.
- Added hvc_find_vtys() function.
- Added hvc_instantiate() function which is implemented by a console
driver wanting to receive a callback of and early console init.
drivers/char/hvc_console.c
==========================
- Switch khvcd from kernel_threads to kthreads which got rid of
deprecated daemonize().
- Added module exit clause to be thorough (not terribly necessary with a
console driver of course)
- Added early discovery of vterm/vty adapters by doing a bus walk on
early console init which results in hvc_instantiate() callback and
addition of the vtermno into a static array of vtermnos supported as
console adapters (meaning the console api's work against these vtermnos
prior to full console initialization).
- This driver is now registered as a vio driver which means that vty
adapters are now managed via probe/remove. This means hvc_console
supports hotplug vty adapters.
- Driver now requests more device nodes than what was found on the
initial bus walk when registered as a tty driver to make room for hotplug
vty adapters. These secondary vty adapters provide a tty tunnel between
partitions.
- Removed static hvc_struct array and replaced with a linux list that has
elements (hvc_struct instances) added/removed on probe/remove AFTER early
console init. This is important because kmalloc can't be done at early
console init.
- Driver now either runs in interrupt driven mode or in polling mode on
older hardware. The khvcd is smart enough to not 'schedule()' when there
are no interrupts.
- kobjects are now used for ref counting on the hvc_struct instances.
- This driver puts the tty layer to sleep on hvc_close() if there are
pending data writes being blocked by firmware.
- Removed useless spinlocks in hvc_chars_in_buffer() and hvc_write_room.

[PATCH] s390: kernel stack options.
This adds support for the new compiler options -mkernel-backchain,
-mstack-size, -mstack-guard, -mwarn-dynamicstack and -mwarn-framesize.
The option -mkernel-backchain enables the use of modified layout for the
stack frames of kernel functions. This breaks the ABI, modules compiled
with the option won't work on a kernel compiled with the option and vice
versa. The positive effect of the option is a drastic reduction of kernel
stack use. The trick is that the new frame layout allows to overlap the 96
(31 bit)/160 (64 bit) byte bias areas of the functions on the call chain.
This lowers the minimal stack usage of a function from 96 bytes to 16 bytes
(31 bit) and 160 bytes to 24 bytes (64 bit). The kernel stack use is
decreased to a point where it is possible to use 4K (31 bit) / 8K (64 bit)
stacks. The split into process stack and interrupt stack is already in
place.
The options -mstack-size and -mstack-guard are used to detect kernel stack
overflows. The compiler adds code to the prolog of every function that
causes an illegal operation if the kernel stack is about to overflow.
The options -mwarn-dynamicstack and -mwarn-framesize cause the compiler to
emit warnings if a function uses dynamic stack allocation or if the
function frame size is bigger then a specified limit.
To play safe all the new options are configurable.

So we hide the page information in the symlink data area itself,
by stealing the last pointer in the page used for the cache. That
way nfs_put_link() can just look up the page directly.

[PATCH] ppc32: fix the 'checkbin' target
The checkbin target on PPC32 isn't quite right.
First, one of the tests (to ensure that some instructions are known to
gas) is never actually invoked because 'checkbin' doesn't know about
stuff set in .config, so we always have the 'else' case run. This
changes to always running the test and telling the user to upgrade to at
least binutils 2.12.1.
The next problem is that we were doing $(AS) -o /dev/null ... in both
that test, as well as another. The problem here is that the checkbin
target is run on the install targets, meaning that /dev/null will get
unlinked when the test passes. To get around this we use .tmp_gas_check
as the output file instead.

[ARM] IXP2000 cleanups to get code upstream
This changeset fixes up all the IXP2000 issues mentioned in the following message:
http://lists.arm.linux.org.uk/pipermail/linux-arm-kernel/...
- Remove page table fixups for IXP2400 systems. There is actually some
confusion b/w myself and Intel on what mappings really needs this and
we still need to determine a proper clean way to do this. When we have
that, we'll add support back in. For now I am still able to boot
on IXP2400 systems.
- Replaced __asm__ __volatile__("":::"memory") with barrier()
- Remove inclusion of mach-types.h in ixdp2x01.h. The machine_is_ixdp2x01()
macro was only being used in one place, so just check for
(machine_is_ixdp2401() || machine_is_ixdp2801())

[IPV4/IPV6]: Fix suboptimal fragment sizing for last fragment
Yoshifuji's recent fragment patch prevents unnecessary fragmentation
when the data can be kept in a single packet, but only for the first
packet. When fragmenting, all fragments are still truncated to
multiples of 8 and we might end up creating an unnecessary fragment.
This dump shows the problem (MTU 1499):
172.16.1.123.32771 > 172.16.195.3.4135: udp 2937 (frag 7066:1472@0+)
172.16.1.123 > 172.16.195.3: udp (frag 7066:1472@1472+)
172.16.1.123 > 172.16.195.3: udp (frag 7066:1@2944)
This patch always builds mtu sized fragments and truncates the previous
fragment to a multiple of 8 bytes when allocating a new one. With the
patch the dump looks like this:
172.16.1.123.32772 > 172.16.195.3.4135: udp 2937 (frag 49641:1472@0+)

- it saves some space = 5*5 ints = 100 bytes in task_struct
- it's smaller and tidy, more straigthforward and doesn't use
any knowledge about pids using and assignment.
- it removes pid_links and pid_struct doesn't hold reference counters
on task_struct. instead, new pid_structs and linked altogether and

[NET]: Add reference counting to neigh_parms.
I've added a refcnt on neigh_parms as well as a dead flag. The latter
is checked under the tbl_lock before adding a neigh entry to the hash
table.
The non-trivial bit of the patch is the first chunk of net/core/neighbour.c.
I removed that line because not doing so would mean that I have to drop
the reference to the parms right there. That would've lead to race
conditions since many places dereference neigh->parms without holding
locks. It's also unnecessary to reset n->parms since we're no longer
in a hurry to see it go due to the new ref counting.
You'll also notice that I've put all dereferences of dev->*_ptr under
the rcu_read_lock(). Without this we may get a neigh_parms that's
already been released.
Incidentally a lot of these places were racy even before the RCU change.
For example, in the IPv6 case neigh->parms may be set to a value that's
just been released.
Finally in order to make sure that all stale entries are purged as
quickly as possible I've added neigh_ifdown/arp_ifdown calls after
every neigh_parms_release call. In many cases we now have multiple
calls to neigh_ifdown in the shutdown path. I didn't remove the
earlier calls because there may be hidden dependencies for them to
be there. Once the respective maintainers have looked at them we
can probably remove most of them.

[PATCH] fix target_cpus() for summit subarch
I've been hunting down a bug affecting IBM x440/x445 systems where the
floppy driver would get spurious interrupts and would not initialize
properly.
After digging James Cleverdon and Bill Irwin pointed out that target_cpus()
is routing the interrupts to the clustered apic broadcast mask using
destFixed deliver mode. This was causing multiple interrupts to show up,
breaking the floppy init code.
This fix simply changes the delivery mode to dest_LowestPrio and initially
routes interrupts to the first cpu to resolve this issue.

[PATCH] ppc[64]: increase max auxv entries
... but a better solution should probably be found, that's saved_auxv
in struct mm_struct is ... hrm... disgusting at least ;)
So the problem is that we currently do
unsigned long saved_auxv[40];
That is we assume that all archs will have an AUXV entry of no more than
2 unsigned longs and we'll have no more than 20 entries in the table.
Unfortunately, this is wrong.
PPC/PPC64 adds 5 platform entries. then we add 14 in the common code,
and then we have
if (k_platform) {
NEW_AUX_ENT(AT_PLATFORM, (elf_addr_t)(unsigned long)u_platform);
}
if (bprm->interp_flags & BINPRM_FLAGS_EXECFD) {
NEW_AUX_ENT(AT_EXECFD, (elf_addr_t) bprm->interp_data);
}
which may add a 20th entry... which means we are already out of room for
the terminating AT_NULL entry... bad bad bad.
Now I'm adding AT_SYSINFO_EHDR to ppc/ppc64 and it breaks all the time.
The quick fix is to bump the number of entries in struct mm_struct to 42,
though that's worth a big BOLD comment in binfmt_elf in case anybody adds
a new entry in there. (Patch below). I wonder if we shouldn't add a
ARCH_MAX_AUXV_ENTRIES macro to the asm-arch/elf.h though to get the max
amount of entry the arch may add to the normal count, and have the mm
struct array use that plus the number of "normal" entries...
This patch increase the max amount of auxv entries in struct mm_struct to
42 so that ppc & ppc64 don't get a chance to blow the array up.

[PATCH] ppc64: pin the kernel stack's SLB entry
This has been given basic testing on Power4 pSeries and iSeries machines.
At present, the SLB miss handler has to check the SLB slot it is about to
use to ensure that it does not contain the SLBE for the current kernel
stack - throwing out the SLBE for the kernel stack can trigger the
"megabug": we have no SLBE for the stack, but we don't fault immediately
because we have an ERAT entry for it. The ERAT entry is then lost due to a
tlbie on another CPU during the unrecoverable section of the exception
return path.
This patch implements a different approach - with this patch SLB slot 2
always (well, nearly always) contains an SLBE for the stack. This slot is
never cast out by the normal SLB miss path. On context switch, an SLBE for
the new stack is pinned into this slot, unless the new stack is the the
bolted segment.
For iSeries we need a special workaround because there is no way of
ensuring the stack SLBE is preserved an a shared processor switch. So, we
still need to handle taking an SLB miss on the stack, in which case we must
make sure it is loaded into slot 2, rather than using the normal
round-robin.
This approach shaves a few ns off the slb miss time (on pSeries), but more
importantly makes it easier to experiment with different SLB castout
aporoaches without worrying about reinstating the megabug.

[PATCH] ppc64: topdown support
Recent patches introduced a top down user process address space allocation
policy; further patches enable this for ppc64. Although these work
correctly for normal maps, the topdown algorithm does not take into account
stringent mixing constraints for small and large pages on this
architecture. These patches introduce a ppc64 specific
arch_get_unused_area_topdown() variant. The first introduces
infrastructure to allow replacement of the generic
arch_get_unused_area_topdown() and the second utilises this infrastructure.
In this patch I have followed the pattern set by the arch_get_unused_area()
using HAVE_ARCH_UNMAPPED_AREA_TOPDOWN to be consistent. However, it would
also be possible to simply have a ppc64_get_unused_area_topdown() in the
arch/ppc64/mm/mmap.c or to use weak bindings.

Implement the HCALLs to do more than one TCE setup or invalidation at a
time on pSeries LPAR. Previous implementation did one hypervisor call per
setup or teardown, resulting in significant overhead.
A simple test of "time dd if=/dev/sda of=/dev/null bs=128k" shows the
amount of system time go down by about 5% by using the multi-tce calls.

[PATCH] ppc64: allocate NUMA node data node locally
Instead of statically allocating the NUMA node structures, do it at runtime
with node local memory where possible. With NR_CPUS=128 we had over 800kB
of memory allocated before this patch, now we allocate only as many nodes
as the machine requires.
We have to do some fancy footwork in do_init_bootmem since we use both the
LMB allocator and the bootmem allocator at the same time. The problem has
always been there although I only recently found a test case that hit it.
Wrap that logic in careful_allocation which uses the LMB allocator then
falls back to the bootmem allocator if required.
Now alloc_bootmem on a node with no memory doesnt panic, we dont need the
hack in paging_init so remove it.

[PATCH] Add support for NUMA discovery on AMD dual core to x86-64
Following the CPUID extensions and APIC-ID setup presented by Richard
Brunner at Kernel Summit.
Without this the kernel's node discovery would assign the wrong nodes on
dual core systems and cause performance degradation.
Only handles power of two cored CPUs, others will be ignored.
/proc/cpuinfo has a new field cpu cores: <number of CPU cores> and also
show the other core as HT sibling (this is needed to make old CPU based
license managers to count one CPU package as only one physical CPU)
FIXME this currently misses the disable code for SMT idle. That's because

later.

[PATCH] Fix argument checking in sched_setaffinity
This patch fixes the argument length checking in sched_setaffinity.
Previously it would error out when the length passed was smaller than
sizeof(cpumask_t). And any bits beyond cpumask_s would be silently
ignored.
First this assumes that the user application knows the size of cpumask_t,
which should be kernel internal. When you increase cpumask_t old
applications break and there is no good way for the application to find out
the cpumask_t size the kernel uses.
This patch changes it to do similar checking to the NUMA API calls:
- Any length is ok as long as all online CPUs are covered (this could
still cause application breakage with more CPUs, but there is no good way
around it)
- When the user passes more than cpumask_t bytes the excess bytes are
checked to be zero.

[PATCH] Add IXDP2x01 board support to CS89x0 driver
The following patch modifies the CS89x0 driver to work on Intel's IXDP2401
and IXDP2801 (Intel ARm/XScale based) platforms:
- The main change requried is that the IXDP2x01 boards have the
chip connected through a CPLD so all registers appear at
dword-aligned addresses. A macro in the header adjusts the register
offsets appropriately.
- The boards do not have ISA, so we need to explicitly check for
IXDP2X01 in Kconfig.
- There is what I believe is a bug in the driver as it currently
only asks for the signature if ioaddr & 1 is set but then
reads and checks against the expected signature even when
!(ioaddr & 1). This causes the driver to not load on the IXDP2x01
since our ioaddr does not have bit 1 set.
- #ifdef out some bits of code that assume the chip is really
sitting on an ISA bus.
The main IXDP2x01 support will be coming in through rmk's tree at
a later date when all the drivers are merged upstream.

[PATCH] Root reservations for strict overcommit
This was on my TODO list for a while and it turns out someone already fixed
the armwaving overcommit mode for the same problem. It is easy to get into
a situation where you have no overcommit and nothing can be done because
there is no memory to clean up the stable but non-useful state of the
machine.
The fix is trivial and duplicated from the armwaving overcommit code path.
The last 3% of the memory can be claimed by root processes only. It isn't
a cure but it does seem to solve the real world problems - at least
providing you have enough memory for 3% to be useful 8).

[PATCH] fix the barrier IDE detection logic
This fixes the logic so we always check for the cache. It also defaults to
safer behaviour for the non cache flush case now we have the right bits in
the right places. I've also played a bit with timings - the worst case
timings I can get for the flush are about 7 seconds (which I'd expect as
the engineering worst cases will include retries)
Probably what should happen is that the barrier logic is enabled providing
the wcache is disabled. I've not meddled with this as I don't know what
the intended semantics and rules are for disabling barrier on a live disk
(eg when a user uses hdparm to turn on the write cache). In the current
code as with Jens original that cannot occur.
I've also fixed the new printk's as per a private request from Matt Domsch.

This patch attempts to sort the CREDITS file properly. No existing entries
were changed, merely moved around in the file. There where a few tricky
names that I was unsure how to sort (names with characters such as ü, ö,
and people with many names where it was unclear to me what name to sort by
etc), in those cases I've usually left the names where they were unless it
was glaringly obvious they were in the wrong spot.
I've also taken the liberty to add my own name to the file - I have
contributed several tiny/small fixes/cleanups etc over the years.

[PATCH] fix sched_domains hotplug bootstrap ordering vs. cpu_online_map issue
cpu_online_map is not set up at the time of sched domain initialization
when hotplug cpu paths are used for SMP booting.
At this phase of bootstrapping, cpu_possible_map can be used by the
various architectures using cpu hotplugging for SMP bootstrap, but the
manipulations of cpu_online_map done on behalf of NUMA architectures,
done indirectly via node_to_cpumask(), can't, because cpu_online_map
starts depopulated and hasn't yet been populated.
On true NUMA architectures this is a distinct cpumask_t from
cpu_online_map and so the unpatched code works on NUMA; on non-NUMA
architectures the definition of node_to_cpumask() this way breaks and
would require an invasive sweeping of users of node_to_cpumask() to
change it to e.g. cpu_possible_map, as cpu_possible_map is not suitable
for use at runtime as a substitute for cpu_online_map.

[PATCH] fix media detection for nForce 2 nics
attached is a patch that polls the media setting for non GigE nForce
nics:
Without polling, media changes are not autodetected. This is fatal,
because the nic initialization is asynchroneous, thus "modprobe;ifup"
resulted in a dead network connection. The attached patch fixes that
problem.
It's a repost of a patch I sent around three weeks ago: you objected
that I rely on the nic irq instead of a software timer. I've documented
why this is ok.

[PATCH] out-of-line locks / generic
This patch achieves out of line spinlocks by creating kernel/spinlock.c
and using the _raw_* inline locking functions.
Now, as much as this is supposed to be arch agnostic, there was still a
fair amount of rummaging about in archs, mostly for the cases where the
arch already has out of line locks and i wanted to avoid the extra call,
saving that extra call also makes lock profiling easier. PPC32/64 was
an example of such an arch and i have added the necessary profile_pc()
function as an example.
Size differences are with CONFIG_PREEMPT enabled since we wanted to
determine how much could be saved by moving that lot out of line too.

Add LOCALVERSION so we can append strings that show up in uname

* config variable is appended last
* LOCALVERSION from the command line overrides all of this
* check is forced on build, since we can't really know when
the config or environment options change.

kbuild: Simplify generating vmlinux
Generating vmlinux in top-level Makefile were getting a bit messy after kallsyms
support were added. Also the full link of all the .o files were duplicaed a number of times.
This patch does the following:
- Introduce built-in.o which is a prelink of most .o files
- Make the build process a bit more verbose telling when linking .tmpvmlinux*
- Use less magic when determing when to generate a new version
- Allow architectures to override the defineition of cmd_vmlinux__
- Add more comments to the MAkefile and clean up soem other comments
- Display more commends during V=1 builds
The resulting kernel boots and rn here.

scripts: Update ver_linux for recent reiserfsprogs
The ver_linux script is fixed to report recent versions of
reiserfsprogs. (Older versions had "reiserfsprogs" in the
line containing the version number, while recent versions
report "reiserfsck" followed by version number).
The ver_linux script is updated to report the reiser4progs
version number.

[TCP]: Make TSO play nice with congestion window.
Previously TSO would not abide by the congestion
window properly. Essentially, each TSO packet would
be trated just like 1 normal packet, even though a TSO
packet generates more than 1 normal packet. This
violates congestion window rules entirely.
So now we record the TSO factor, a count of how many
real packets a TSO packet will generate, and include
this in all the packet counting routines.
This initial version has a bug in that skb_entail() is
not the correct time to figure out the TSO factor for
the SKB, and tp->mss_tso_factor is not necessarily the
right value for a given SKB. Will fix this up next.

[NET]: Fully plug netigh_create/inetdev_destroy race.
So here is a patch to make sure that there is a barrier between the
reading of dev->*_ptr and *dev->neigh_parms.
With these barriers in place, it's clear that *dev->neigh_parms can no
longer be NULL since once the parms are allocated, that pointer is never
reset to NULL again. Therefore I've also removed the parms check in
these paths.
They were bogus to begin with since if they ever triggered then we'll
have dead neigh entries stuck in the hash table.
Unfortunately I couldn't arrange for this to happen with DECnet due
to the dn_db->parms.up() call that's sandwiched between the assignment
of dev->dn_ptr and dn_db->neigh_parms. So I've kept the parms check
there but it will now fail instead of continuing. I've also added an
smp_wmb() there so that at least we won't be reading garbage from
dn_db->neigh_parms.
DECnet is also buggy since there is no locking at all in the destruction
path. It either needs locking or RCU like IPv4.

[NET]: Fix compat layer setsockopt overzealous conversions.
compat_sys_setsockopt() is a little overzealous about converting 32-bit
stuff into 64-bit. It should match on level _and_ optname, not just
optname. Currently it eats the IPV6_V6ONLY sockopt because its value
(26) happens to match SO_ATTACH_FILTER.
This makes it at least check 'level' for everything but
IPT_SO_SET_REPLACE == IPT6_SO_SET_REPLACE, because that does seem to be
the same in different levels. But do_netfilter_replace() is another can
of worms entirely -- it doesn't actually work either, because some
netfilter modules (like ipt_limit) include kernel-only bits which change

[PATCH] SN2 build fix CONFIG_VIRTUAL_MEM_MAP and CONFIG_DISCONTIGMEM
The change on 2004-09-03 by ianw@gelato.unsw.edu.au appears to have
a typo, which causes builds of configurations which define both
CONFIG_VIRTUAL_MEM_MAP and CONFIG_DISCONTIGMEM to emit some 890
warnings for redefines of each of pfn_valid, page_to_pfn,
pfn_to_page.
This shows up compiling sn2_defconfig, the SN2 config of arch ia64. I
believe that this is a simply typo, an extra "#else" line. Removing

[PATCH] input: Fix hiddev disconnect-while-in-use oops
hid-core calls hiddev_disconnect() when the underlying device goes away
(hot unplug or system shutdown). Normally, hiddev_disconnect() will clean
up nicely and return to hid-core who then frees the hid structure.
However, if the corresponding hiddev node is open at disconnect time,
hiddev delays the majority of disconnect work until the device is closed
via hiddev_release(). hiddev_release() calls hiddev_cleanup() which
proceeds to dereference the hid struct which hid-core freed back when the
hardware was disconnected. Oops.
To solve this, we change hiddev_disconnect() to deregister the hiddev minor
and invalidate its table entry immediately and delay only the freeing of
the hiddev structure itself. We're protected against future operations on
the fd since the major fops check hiddev->exists.

[PATCH] Time interpolator: Scalability enhancements and high resolution time for IA64
This has been in the ia64 (and hence -mm) trees for a couple of months.
Changelog:
* Affects only architectures which define CONFIG_TIME_INTERPOLATION
(currently only IA64)
* Genericize time interpolation, make time interpolators easily usable
and provide instructions on how to use the interpolator for other
architectures.
* Provide nanosecond resolution for clock_gettime and an accuracy
up to the time interpolator time base.
* clock_getres() reports resolution of underlying time basis which
is typically <50ns and may be 1ns on some systems.
* Make time interpolator self-tuning to limit time jumps
and to make the interpolators work correctly on systems with
broken time base specifications.
* SMP scalability: Make clock_gettime and gettimeofday scale O(1)
by removing the cmpxchg for most clocks (tested for up to 512 CPUs)
* IA64: provide asm fastcall that doubles the performance
of gettimeofday and clock_gettime on SGI and other IA64 systems
(asm fastcalls scale O(1) together with the scalability fixes).
* IA64: provide nojitter kernel option so that IA64 systems with
correctly synchronized ITC counters may also enjoy the
scalability enhancements.

This patch makes the PPC64 SLB miss handler run in real mode (i.e. MMU
off) for it's whole duration, on pSeries machines. Avoiding the rfid used
to turn relocation on saves some 70-80 cycles on Power4 and Power5. Not
having to save and restore SRR0 and SRR1 saves a few more, and means we
don't need an extra save slot for r3. Overall there's around a 27% speedup

It also fixes the logic on when to ask cpufreq for a new estimate.

- ppc added a new preemptible() macro that is provided for all

[PATCH] cleanup ptrace stops and remove notify_parent
This adds a new state TASK_TRACED that is used in place of TASK_STOPPED
when a thread stops because it is ptraced. Now ptrace operations are only
permitted when the target is in TASK_TRACED state, not in TASK_STOPPED.
This means that if a process is stopped normally by a job control signal
and then you PTRACE_ATTACH to it, you will have to send it a SIGCONT before
you can do any ptrace operations on it. (The SIGCONT will be reported to
ptrace and then you can discard it instead of passing it through when you
call PTRACE_CONT et al.)
If a traced child gets orphaned while in TASK_TRACED state, it morphs into
TASK_STOPPED state. This makes it again possible to resume or destroy the
process with SIGCONT or SIGKILL.
All non-signal tracing stops should now be done via ptrace_notify. I've
updated the syscall tracing code in several architectures to do this
instead of replicating the work by hand. I also fixed several that were
unnecessarily repeating some of the checks in ptrace_check_attach. Calling
ptrace_check_attach alone is sufficient, and the old checks repeated before
are now incorrect, not just superfluous.
I've closed a race in ptrace_check_attach. With this, we should have a
robust guarantee that when ptrace starts operating, the task will be in
TASK_TRACED state and won't come out of it. This is because the only way
to resume from TASK_TRACED is via ptrace operations, and only the one
parent thread attached as the tracer can do those.
This patch also cleans up the do_notify_parent and do_notify_parent_cldstop
code so that the dead and stopped cases are completely disjoint. The
notify_parent function is gone.

stopped in ptrace_stop (though there are no associated races to worry

[PATCH] Remove RUSAGE_GROUP
After my cleanup of the rusage semantics was so quickly taken in by Andrew
and Linus without comment, I wonder if I should not have tried to be so
accommodating of potential objections as I was. :-)
In my original posting, I solicited comment on whether introducing
RUSAGE_GROUP as distinct from RUSAGE_SELF was warranted. Note that we've
now changed the behavior of the times system call when using CLONE_THREAD,
so changing getrusage RUSAGE_SELF to match would be consistent. I think
that changing the meaning of the old RUSAGE_SELF value is preferable to
introducing the new value for the proper POSIX getrusage behavior. This
patch against Linus's current tree dumps RUSAGE_GROUP and makes RUSAGE_SELF
have the fixed behavior.
If there is interest in having a new explicit interface to sample a single
thread's stats alone, then I think that would be better done by introducing
a new value for RUSAGE_THREAD. This is trivial to implement, but I won't
offer patches bloating the interface if noone is actually interested in
using it.

[PATCH] make single-step into signal delivery stop in handler
On x86 and x86-64, setting up to run a signal handler clears the
single-step bit (TF) in the processor flags before starting the handler.
This makes sense when a process is handling its own SIGTRAPs.
But when TF is set because PTRACE_SINGLESTEP was used, and that call
specified a handled signal so the handler setup is happening, it doesn't
make so much sense. When the debugger stops to show you a signal about to
be delivered, and that signal should be handled, and then you do step or
stepi, you expect to see the signal handler code. In fact, the signal
handler runs to completion and then you see the single-step trap at the
resumed code instead of seeing the handler.
This patch changes signal handler setup so that when TF is set and the
thread is under ptrace control, it synthesizes a single-step trap after
setting up the PC and registers to start the handler. This makes that
PTRACE_SINGLESTEP not strictly a "step", since it actually runs no user
instructions at all. But it is definitely what a debugger user wants, so
that single-stepping always stops and shows each and every instruction
before it gets executed.

[PATCH] fs/compat.c: rwsem instead of BKL around ioctl32_hash_table
Currently the BKL is used to synchronize access to ioctl32_hash_table in
fs/compat.c. It seems that an rwsem would be more appropriate, since this
would allow multiple lookups to occur in parallel (and also serve the
general good of minimizing use of the BKL).
I added lock_kernel()/unlock_kernel() around the call to t->handler when a
compatibility handler is found in compat_sys_ioctl() to preserve the
expectation that the BKL will be held during driver ioctl operations. It
should be safe to do lock_kernel() while holding ioctl32_sem because of the
magic BKL sleep semantics.

[PATCH] fbcon: take over console on driver registration
- This fixes another regression from 2.4. If fbcon is compiled
statically, and the framebuffer driver is compiled as a module, doing a
'modprobe xxxfb' does nothing to the console. This has generated
numerous bug reports from users.
With this patch, fbmem will notify fbcon upon driver registration
allowing fbcon to take over the console.
- This also fixes con2fbmap not working if fbcon is compiled as a module
using the same mechanism as described above.

[PATCH] fbdev: Clean up framebuffer initialization
This patch probably deserves discussion among developers.
Currently, the framebuffer system is initialized in a roundabout manner.
First, drivers/char/mem.c calls fbmem_init(). fbmem_init() will then
iterate over an array of individual drivers' xxxfb_init(), then each driver
registers its presence back to fbmem. During console_init(),
drivers/char/vt.c will call fb_console_init(). fbcon will check for
registered drivers, and if any are present, will call take_over_console()
in drivers/char/vt.c.
This patch changes the initialization sequence so it proceeds in this
manner: Each driver has its own module_init(). Each driver calls
register_framebuffer() in fbmem.c. fbmem.c will then notify fbcon of the
driver registration. Upon notification, fbcon calls take_over_console() in
vt.c.
The following are the changes brought about by this patch:
- Each subsystem (fbcon, fbmem, xxxfb) will have their own module_init.
Thus, explicit calls to each subsystem's init functions are eliminated.
- The struct fb_drivers array in fbmem.c can be removed. This slashes
around 400 lines in fbmem.c
- Parsing of kernel boot options were done by fbmem.c calling each
driver's xxxfb_setup() function. Because this is not possible with this
patch, drivers can choose to either:
- have their own __setup() routine
- call fb_get_options("xxxfb") and pass the return value to
xxxfb_setup(). This is to maintain compatibility with the
'video=xxxfb:<options>' semantics.
- Getting a framebuffer console will occur a bit late during the boot
process since the initialization sequence will depend upon the link
order. So, 'video/' is moved up in drivers/Makefile, shortly after
'pci/'
- Because driver initialization will be dependent on the link order,
hardware that depends on other subsystems (agpgart, usb, serial, etc) may
choose to initialize after the subsystems they depend on.

were rearming the buffer sync timer without modifying the expire time.
Now that we have schedule_delayed_work_on I believe we can remove the timer
completely. Each cpu should be offset by 1 jiffy so they dont all fire at
the same time. I bumped DEFAULT_TIMER_EXPIRE from 2 to 10 times a second
to be sure we reap cpu buffers.
With the following patch the same large machine gets about 4000 context
switches per second.

[NET]: NETIF_F_LLTX for devices
New version of the NETIF_F_LLTX for network devices patch.
This allows network drivers to set the NETIF_F_LLTX flag
and then do their own locking in start_queue_xmit.
This lowers locking overhead in this critical path.
The drivers can use try lock if they want and return -1
when the lock wasn't grabbed. In this case the packet
will be requeued. For better compatibility this is only
done for drivers with LLTX set, others don't give a special
meaning to -1.
Most of the modern drivers who have a lock around hard_start_xmit
can just set this flag. It may be a good idea to convert the spin
lock there to a try lock. The only thing that should be audited
is that they do enough locking in the set_multicast_list function
too, and not also rely on xmit_lock here.
Now doesn't move any code around and does things with gotos instead.
The loop printk is also still there even for NETIF_F_LLTX
For drivers that don't set the new flag nothing changes.

[PATCH] ppc/ppc64: fix offb
The recent fbdev changes broke something quite fundamental on ppc, which
is the way offb works. It's a "fallback" driver that is to be used when
no other driver picked up the video, or when "forced" via the video=ofonly
command line option.
The recent changes completely broke that (which is a pretty important
behaviour on ppc since we still have some models regulary with video
cards that don't work properly with the kernel drivers, like some nVidias
or some older stuffs).
This patch moves offb to the end of the Makefile, so at least the behaviour
of taking over as a "fallback" is restored (the current kernel will have
offb take control of the framebuffer before any fbdev has a chance to do
it, which breaks everything).
Apparently, the entire support for "video=ofonly" was removed though,
that NEEDS to be restored in some way, though i'm not yet sure what is
the best path to that yet, I have to look more deeply at the new code.

[IPSEC]: Find larval SAs by sequence number
When larval states are generated along with ACQUIRE messages, we should

If we don't do that, then it may take down an unrelated larval state
with the same parameters (think different TCP sessions). This not only
leaves behind a larval state that shouldn't be there, it may also cause
another ACQUIRE message to be sent unnecessarily.

[IPCOMP]: Use per-cpu buffers for compression/decompression.
Here is a really ugly patch to get IPCOMP to use per-cpu buffers. But
I'm afraid it really is necessary. At 300K per SA IPCOMP isn't very
affordable at all.
With per-cpu buffers this goes down to 300K per CPU.
I've also turned the kmalloc'ed scratch space into a vmalloc'ed one
since people may be loading the ipcomp module after the system has
been running for a while. On an i386 machine with 64M of RAM or less
this can often cause a 64K kmalloc to fail.
The crypto deflate buffer space are vmalloc'ed already as well.
Part of the ugliness comes from the lazy allocation. However we need
the lazy initialisation since new IPCOMP algorithms may be introduced
in future. That means we can't allocate space for every single IPCOMP
algorithm at module-load time.

The fix is very simple, since tcp_retransmit_skb()

ppc: make IDE memory-mapped PCI routines match new reality

[IPV6]: Fix oops in rt6_device_match()
This fixes panic in rt6_device_match().
Well, rt->rt6i_idev is always set if it is dynamically allocated.
However, when we hit ip6_null_entry here, its rt6i_idev is NULL.
This patch is minimum fix to avoid the oops for now.

[IPVS]: Do not use skb_checksum_help(), create and use nf_reset_debug()
Appended is a 2nd version that uses nf_reset_debug.
- do not use skb_checksum_help in input path as ipvs can handle
incoming CHECKSUM_HW packets
- do not use skb_checksum_help in forwarding path
- claim that checksum is valid (CHECKSUM_NONE) when entering output
path for out->in packets
- do not reset/destroy the nfct in IP_VS_XMIT, the intention is to
reset the debugging field just to avoid log floods from nf_debug_ip_*
functions, it is known that the ipvs packets traverse other
hooks, eg. LOCAL_IN->LOCAL_OUT. Use nf_reset_debug instead of nf_reset.

[NETFILTER]: Fix conntrack seq_file handling.
Am travelling, but this passed simple tests here. If this isn't going
in, the current seqfile stuff should be ripped out; it's a mess.
/proc/net/ip_conntrack was changed over to seq_file. However,
seq_file isn't a great fit (a linked list which is changing is not a
good candidate for seq file), and the conversion was done badly.
1) Don't do allocation: simply hand the pointer head of the correct chain.
2) Actually output the original tuple.
3) Lock only when actually traversing hash chain.

[PATCH] fbdev/radeonfb: Remove bugus radeonfb_read/write
This patch kills the bogus radeonfb_read/write routines. In order to do so,
it adds a new member to fb_info, along with screen_base, which is screen_size,
indicating the mapped area. The default fb_read/write will now use that instead
of fix->smem_len if it is non-0, and radeonfb now sets it to the mapped size
of the framebuffer.
