[PATCH] Fix aic7xxx_osm.c compile with older gcc's
My version of gcc doesn't warn about this error (declaration in the
middle of a set of statements).
The fix is simple (this also corrects return code; for init functions it
should be zero or error).

[PATCH] x86_64: Bug in new out of line put_user()
The new out of line put_user() assembly on x86_64 changes %rcx without

[IA64] fix fls()
The ia64-version of fls() never worked as intended (the bitnumbering
was off by 1 and fls(0) was undefined). This patch fixes the problem
by using a popcnt-based fls(), which on McKinley-derived cores is
slightly faster than both ia64_fls() and generic_fls(). The resulting
code, however, is bigger (7-8 bundles instead of about 3 bundles).
Also switch ia64_popcnt() to __builtin_popcountl() for GCC v3.4 or
newer since the compiler can predicate that and schedule it better.
Thanks to Simon Derr and Matt Mackall for tracking down this bug.

[IA64] cpu hotplug: return offlined cpus to SAL
This patch is required to support cpu removal for IPF systems. Existing
code
just fakes the real offline by keeping it run the idle thread, and polling
for the bit to re-appear in the cpu_state to get out of the idle loop.
For the cpu-offline to work correctly, we need to pass control of this CPU
back to SAL so it can continue in the boot-rendez mode. This gives the
SAL control to not pick this cpu as the monarch processor for global MCA
events, and addition does not wait for this cpu to checkin with SAL
for global MCA events as well. The handoff is implemented as documented in
SAL specification section 3.2.5.1 "OS_BOOT_RENDEZ to SAL return State"

[PATCH] USB: scripts/mod/file2alias.c: handle numeric ranges for USB
bcdDevice
Another attempt at that...
The attached patch fixes the longstanding problem with USB bcdDevice
numeric ranges incorrectly converted into patterns for MODULE_ALIAS
generation. Previously it put both the lower and the upper limits into
the pattern, dlXdhY, making it impossible to fnmatch against except for
a few special cases, like dl*dh* or dlXdhX.
The patch makes it generate multiple MODULE_ALIAS lines covering the
whole range with fnmatch-able patterns. E.g. for a range between 0x0001
and 0x8345 it gives the following patterns:
000[1-9]
00[1-9]*
0[1-9]*

[PATCH] USB: better usbnet zaurus/mdlm/... fix
This is a somewhat more comprehensive fix for the problem of devices
like the newer Zaurii ... or in this case some Motorola cell phones.
To recap, the problem's root cause is that these devices aren't using
standard USB class specifications for their network links, and so far
we've had to add lots of device-specific driver entries. The vendor
fix abuses the CDC MDLM descriptors (they _could_ have conformed to
the spec, but didn't) and defines a "Belcarra firmware" pseudo-class.
This patch recognizes that pseudo-class by the GUIDs in those descriptors,
and handles the devices that just use the Zaurus framing.

[NETFILTER]: Fix NAT sequence number adjustment
The NAT changes in 2.6.11 changed the position where helpers
are called and perform packet mangling. Before 2.6.11, a NAT
helper was called before the packet was NATed and had its
sequence number adjusted. Since 2.6.11, the helpers get packets
with already adjusted sequence numbers.
This breaks sequence number adjustment, adjust_tcp_sequence()
needs the original sequence number to determine whether
a packet was a retransmission and to store it for further
corrections. It can't be reconstructed without more information
than available, so this patch restores the old order by
calling helpers from a new conntrack hook two priorities

to be superfluous.
I was just reading ipv6_skip_exthdr and it occured to me that we can
get rid of len altogether. The only place where len is used is to
check whether the skb has two bytes for ipv6_opt_hdr. This check
is done by skb_header_pointer/skb_copy_bits anyway.
Now it might appear that we've made the code slower by deferring
the check to skb_copy_bits. However, this check should not trigger
in the common case so this is OK.

[IA64] fix syscall-optimization goof
Sadly, I goofed in this syscall-tuning patch:
ChangeSet 1.1966.1.40 2005/01/22 13:31:05 davidm@hpl.hp.com
[IA64] Improve ia64_leave_syscall() for McKinley-type cores.
Optimize ia64_leave_syscall() a bit better for McKinley-type cores.
The patch looks big, but that's mostly due to renaming r16/r17 to r2/r3.
Good for a 13 cycle improvement.
The problem is that the size of the physical stacked registers was
loaded into the wrong register (r3 instead of r17). Since r17 by
coincidence always had the value 1, this had the effect of turning
rse_clear_invalid into a no-op. That poses the risk of leaking kernel
state back to user-land and is hence not acceptable.

[IA64] fix ia64 Kconfig to allow CONFIG_PM on sn2
This probably should have been fixed when I fixed up the generic build for
discontig+numa machines, but oh well.
CONFIG_PM is allowable for generic builds but not for sn2 builds, which
doesn't make much sense, and in fact breaks the build if recent ACPI bits
are
added to the tree. It looks like the only arch that needs to prevent
CONFIG_PM stuff is the ski simulator (though those options could probably
use
some cleanup as well), so remove the big conditional and replace it with a
simple test for IA64_HP_SIM instead.

[TG3]: Fix bug in tg3_rx()
This patch fixes a bug that causes tg3_has_work() to always return 1.
rx work is determined by comparing tp->rx_rcb_ptr with the current hw
producer index. The hw producer index is modulo the ring size, but tp-
>rx_rcb_ptr is a free running counter that goes up beyond the ring size.
After the ring wraps around once, tg3_has_work() will always return 1.
The fix is to always do modulo arithmetic on tp->rx_rcb_ptr.

[TG3]: Fix tg3_restart_ints()
tg3_restart_ints() is called to re-enable interrupts after tg3_poll()
has finished all the work. It calls tg3_cond_int() to force an interrupt
if the status block updated bit is set. The updated bit will be set if
there is a new status block update sometime during tg3_poll() and it can
be very often. The worst part is that even if all the work has been
processed, the updated bit remains set and an interrupt will be forced
unnecessarily.
The fix is to call tg3_has_work() instead to determine if new work is
posted before forcing an interrupt. The way to force an interrupt is
also changed to use "coalesce_now" instead of "SETINT". The former is
generally a safer way to force the interrupt.

Thus the time is set too early and gettimeofday will return a time

Patch from Lennert Buytenhek
The IXDP2800 is an evalution platform for the IXP2800 processor that

as both CPUs will try to configure the PCI bus as they boot linux.
Contrary to on the other IXP2000 platforms, the boot loader on the
IXDP2800 doesn't configure the PCI bus properly, so we do want the
linux instance on one of the CPUs to do that.
Making one of the CPUs ignore the PCI bus (and thus act like a pure
PCI slave device) is not an option because there is a 82559 NIC on
the PCI bus for each of the CPUs.
The chosen solution is to have the master CPU configure the PCI bus

[PATCH] ppc64: fix 32-bit signal frame back link
When the kernel creates a signal frame on the user stack, it puts the
old stack pointer value at the beginning so that the signal frame is
linked into the chain of stack frames like any other frame.
Unfortunately, for 32-bit processes we are writing the old stack
pointer as a 64-bit value rather than a 32-bit value, and the process
sees that as a null pointer, since it only looks at the first 32 bits,
which are zero since ppc is bigendian and the stack pointer is below
4GB. This bug is in SLES9 and RHEL4 too, hence the ccs.
This patch fixes the bug by making the signal code write the old stack
pointer as a u32 instead of an unsigned long.

Note that there is still a trivial'ish change to make. When mkimage

Mempools have 2 problems.
The first is that mempool_alloc can possibly get stuck in __alloc_pages

The second is that it will happily eat emergency PF_MEMALLOC reserves
instead of going to their reserved pools.
Fix the first by passing __GFP_NORETRY in the allocation calls in

[PATCH] mempool: simplify alloc
Mempool is pretty clever. Looks too clever for its own good :) It
shouldn't really know so much about page reclaim internals.
- don't guess about what effective page reclaim might involve.
- don't randomly flush out all dirty data if some unlikely thing
happens (alloc returns NULL). page reclaim can (sort of :P) handle
it.
I think the main motivation is trying to avoid pool->lock at all costs.
However the first allocation is attempted with __GFP_WAIT cleared, so it
will be 'can_try_harder' if it hits the page allocator. So if allocation
still fails, then we can probably afford to hit the pool->lock - and
what's
the alternative? Try page reclaim and hit zone->lru_lock?

[PATCH] i386: fix hpet for systems that don't support legacy replacement
Currently the i386 HPET code assumes the entire HPET implementation from

optional legacy timer replacement functionality portion of the spec.
This patch, which is very similar to my x86-64 patch for the same issue,
fixes the problem allowing i386 systems that cannot use the HPET for the
timer interrupt and RTC to still use the HPET as a time source. I've
tested this patch on a system systems without HPET, with HPET but without
legacy timer replacement, as well as HPET with legacy timer replacement.

The specifications that talk about E820 map doesn't have an upper limit on
the number of e820 entries. But, today's kernel has a hard limit of 32.
With increase in memory size, we are seeing the number of E820 entries
reaching close to 32. Patch below bumps the number upto 128.
The patch changes the location of EDDBUF in zero-page (as it comes after

As, EDDBUF is not used by boot loaders, this patch should not have any
effect

It seems, that disable_irq() cannot be called from interrupts, because it

blocks one CPU after another. Solved by use disable_irq_nosync.

[PATCH] procfs: Fix hardlink counts
The pid directories in /proc/ currently return the wrong hardlink count -
3,
when there are actually 4 : ".", "..", "fd", and "task".
This is easy to notice using find(1):
cd /proc/<pid>

In the output, you'll see a message similar to:

filesystem driver. Automatically turning on find's -noleaf option.
Earlier results may have failed to include directories that should have

[PATCH] procfs: Fix hardlink counts for /proc/<PID>/task
The current logic assumes that a /proc/<PID>/task directory should have a
hardlink count of 3, probably counting ".", "..", and a directory for a
single child task.
It's fairly obvious that this doesn't work out correctly when a PID has
more than one child task, which is quite often the case.

[PATCH] Deprecate synchronize_kernel, GPL replacement
The synchronize_kernel() primitive is used for quite a few different
purposes:
waiting for RCU readers, waiting for NMIs, waiting for interrupts, and so
on.
This makes RCU code harder to read, since synchronize_kernel() might or
might
not have matching rcu_read_lock()s. This patch creates a new
synchronize_rcu() that is to be used for RCU readers and a new
synchronize_sched() that is used for the rest. These two new primitives
currently have the same implementation, but this is might well change with
additional real-time support. Both new primitives are GPL-only, the old
primitive is deprecated.

It's trivial for the resize option to auto-get the underlying device size,

Since of the different reiserfs option parser (which does not use the
superior match_token used by almost every other filesystem), I've had to
use the "resize=auto" and not "resize" option to specify this behaviour.
Changing the option parser to the kernel one wouldn't be bad but I've no

[PATCH] vgacon: set vc_hi_font_mask correctly
When allocating a new VC with vgacon_init(), the font is shared across all
the VGA consoles. However, the font mask was always set to the default
value of zero in visual_init(), even if we were using 512 character fonts
at the time.
Moreover, code in vgacon.c:vga_do_font_op() didn't reset the mask if the
console driver thinks it's already in 512 character mode. This means that
to *fix* it, you'd actually have to take the console out of 512 character
mode and then set it back.
The attached sets vc_hi_font_mask in vgacon_init() for any new consoles
opened if the vgacon driver is already in 512 character mode, solving
this.
This bug goes back to 2.4.18 at least, probably earlier.

[PATCH] ext3: remove unnecessary race then retry in ext3_get_block
The extra race-with-truncate-then-retry logic around
ext3_get_block_handle(), which was inherited from ext2, becomes unecessary
for ext3, since we have already obtained the ei->truncate_sem in
ext3_get_block_handle() before calling ext3_alloc_branch(). The
ei->truncate_sem is already there to block concurrent truncate and block
allocation on the same inode. So the inode's indirect addressing tree
won't be changed after we grab that semaphore.
We could, after get the semaphore, re-verify the branch is up-to-date or
not. If it has been changed, then get the updated branch. If we still
need block allocation, we will have a safe version of the branch to work

[PATCH] ppc64: fix gcc 4.0 vs CONFIG_ALTIVEC
gcc-4.0 generates altivec code implicitly when -mcpu indicates an
altivec capable CPU which is not suitable for the kernel. However, we
used to set -mcpu=970 when CONFIG_ALTIVEC was set because a gcc-3.x bug
prevented from using -maltivec along with -mcpu=power4, thus prevented
building the RAID6 altivec code.
This patch fixes all of this by testing for the gcc version. If 4.0 or
later, just normally use -mcpu=power4 and let the RAID6 code add
-maltivec to the few files it needs to be compiled with altivec support.
For 3.x, we still use -mcpu=970 to work around the above problem, which
is fine as 3.x will never implicitly generate altivec code.

Here is a little optimisation for the cb_lock used by netlink_dump.
While fixing that race earlier, I noticed that the reference count

to obtain the protection of the reference count, you have to take
the cb_lock. But the only way to take the cb_lock is through
dereferencing the socket.
That is, you must already possess a reference count on the socket
before you can take advantage of the reference count held by cb_lock.
As a corollary, we can remve the reference count held by the cb_lock.

Proposed solutions:
a) Synchronous processing.
b) Stream mode socket.
c) Restrict/prohibit binding.
2) Starvation: Because various netlink rcv functions were written
to not return until all messages have been processed on a socket,
it is possible for these functions to execute for an arbitrarily

[PATCH] USB cypress_m8: update kernel driver with current source
Fixed problem where setting or retreiving the serial config would fail
with EPIPE. Removed CRTS toggling so the driver behaves more like other
usbserial adapters. Issued new interval of 1ms instead of the default
bInterval. As a result, transfer speed has been substantially
increased. From avg. 850bps to avg. 3300bps. Also added new module
parameter 'interval' to tweak the interval in case this change causes
problems for someone. Cleaned up code and formatting issues so source
is more readable. Replaced the C++ style comments. Various other code
cleanups.

[PATCH] ISA DMA Kconfig fixes - part 1
A bunch of drivers use ISA DMA helpers or their equivalents for
platforms that have ISA with different DMA controller (a lot of ARM

CONFIG_ISA is not it (e.g. it is not set on platforms that have no ISA
slots, but have on-board devices that pretend to be ISA ones).
New symbol added - ISA_DMA_API. Set when we have functional
enable_dma()/set_dma_mode()/etc. set of helpers. Next patches in the
series will add missing dependencies for drivers that need them.
I'm very carefully staying the hell out of the recurring flamefest on
what exactly CONFIG_ISA would mean in ideal world - added symbol has a

With 2.6.11 and 2.6.12-rc2 (and perhaps a few versions before) usb

It turns out to be due to a bug in drivers/base/bus.c:driver_detach(),

It also moves _PATCHKEY into a new file, patchkey.h, in order to remove a
duplicate definition of it from awe_voice.h.

[PATCH] ppc64: pgtable.h and other header cleanups
This patch started as simply removing a few never-used macros from
asm-ppc64/pgtable.h, then kind of grew. It now makes a bunch of
cleanups to the ppc64 low-level header files (with corresponding
changes to .c files where necessary) such as:
- Abolishing never-used macros
- Eliminating multiple #defines with the same purpose
- Removing pointless macros (cases where just expanding the
macro everywhere turns out clearer and more sensible)
- Removing some cases where macros which could be defined in
terms of each other weren't
- Moving imalloc() related definitions from pgtable.h to their
own header file (imalloc.h)
- Re-arranging headers to group things more logically

potential problem is that I have to modify arch/x86_64/kernel/module.c, to

I can't use it verbatim because it depends on a special vmalloc-like area

not.

[PATCH] DAC960: add support for Mylex AcceleRAID 4/5/600
This patch adds support for a new class of DAC960 controllers. It's based
on the GPLed idac320 driver from IBM for Linux 2.4.18. That driver is a
fork of the 2.4.18 version of DAC960 that adds support for this new type
of
controllers (internally called "GEM Series"), that differ from other
DAC960
V2 firmware controllers only in the register offsets and removes support
for all others.
This patch instead integrates support for these controllers into the
DAC960
driver.
Thanks to Anders Norrbring for pointing me to the idac320 driver and
testing this patch.

[PATCH] bttv: fix dst i2c read/write timeout failure.
Attached is a patch to bttv which fixes the following problems.
Affected cards and problems:
~~~~~~~~~~~~~~~~~~~~~~~~
o VP-1020 (200103A) Tuning problems, device detection.
o VP-1020 (DST-MOT) Errors during tuning, device detection fails in a
while.
o VP-1030 (DST-CI) Tuning sometimes fails after CI commands.
o VP-2031 (DCT-CI) Tuning problems
The timeout happens before the actual timeout occured in the MCU
on the board, and hence the problems.
Changes: (bttv-i2c.diff)
~~~~~~~~~~~~~~~~~~~~~~~~
o Changed the custom wait queue to wait_event_interruptible_timeout()
- Suggestion by Johannes Stezenbach.
o Fixed the wait queue timeout problem

[PATCH] uml: S390 preparation, peekusr/pokeusr defined by subarch
s390 needs to change some parts of arch/um/kernel/ptrace.c. Thus, the
code
regarding PEEKUSER and POKEUSER are shifted to
arch/um/sys-<subarch>/ptrace.c.
Also s390 debug registers need to be updated, when singlestepping is
switched
on / off. Thus, setting/resetting of singlestepping is centralized in the
new
function set_singlestep(), which also inserts the macro
SUBARCH_SET_SINGLESTEP(mode), if defined.
Finally, s390 has the "ieee_instruction_pointer" in its
registers, which also is allowed to be read via
ptrace( PTRACE_PEEKUSER, getpid(), PT_IEEE_IP, 0);
To implement this feature, sys_ptrace inserts the macro

[PATCH] uml: Eliminate unusable function
Eliminate the non-inline version of switch_mm, which can't be used,
considering the inline version in asm/mmu_context.h

[PATCH] uml: Fix process exit race
tt-mode closes switch_pipes in exit_thread_tt and kills processes in
switch_to_tt, if the exit_state is EXIT_DEAD or EXIT_ZOMBIE.
In very rare cases the exiting process can be scheduled out after having
set
exit_state and closed switch_pipes (from release_task it calls
proc_pid_flush,
which might sleep). If this process is to be restarted, UML failes in
switch_to_tt with:
write of switch_pipe failed, err = 9
We fix this by closing switch_pipes not in exit_thread_tt, but later in
release_thread_tt. Additionally, we set switch_pipe[0] = 0 after closing.
switch_to_tt must not kill "from" process depending on its exit_state, but

[PATCH] uml: Use CONFIG variable for address space size
tt/mem.c still uses hardcoded TOP for i386 instead of CONFIG_TOP_ADDR
provided
by subarch's Kconfig_XXXX, which would be right.

[PATCH] uml: Makefile cleanup
This eliminates some stuff from arch/um/kernel/Makefile which refers to a

[PATCH] uml: Turn literal numbers into symbolic constants
So, there I was, looking at my own code, wondering what the magic setjmp
return values did. This patch turns the constants that are used to make
requests of the initial thread into meaningful symbols.

[PATCH] uml: S390 preparation, arch_align_stack
Only x86 and x86_64 use arch_align_stack(), all other subarches have:
#define arch_align_stack(x) (x)
So, if this definition is found, UML's own arch_align_stack() should be
skipped.

[PATCH] uml: x86_64 fixes
This fixes some x86_64 bugs -
- maybe_map returns -1 on error instead of 0, which is interpreted as
physical address 0
- removed an include of ipc.h, which isn't needed
- fixed the calculation of signal frame location
- the signal delivery code is now immune to the stack expansion check
- added a missing include
