[ARM] 3762/1: Fix ptrace cache coherency bug for ARM1136 VIPT nonaliasing Harvard caches
Patch from George G. Davis
Resolve ARM1136 VIPT non-aliasing cache coherency issues observed when
using ptrace to set breakpoints and cleanup copy_{to,from}_user_page()
while we're here as requested by Russell King because "it's also far
too heavy on non-v6 CPUs".
NOTES:
1. Only access_process_vm() calls copy_{to,from}_user_page().
2. access_process_vm() calls get_user_pages() to pin down the "page".
3. get_user_pages() calls flush_dcache_page(page) which ensures cache
coherency between kernel and userspace mappings of "page". However
flush_dcache_page(page) may not invalidate I-Cache over this range
for all cases, specifically, I-Cache is not invalidated for the VIPT
non-aliasing case. So memory is consistent between kernel and user
space mappings of "page" but I-Cache may still be hot over this
range. IOW, we don't have to worry about flush_cache_page() before
memcpy().
4. Now, for the copy_to_user_page() case, after memcpy(), we must flush
the caches so memory is consistent with kernel cache entries and
invalidate the I-Cache if this mm region is executable. We don't
need to do anything after memcpy() for the copy_from_user_page()
case since kernel cache entries will be invalidated via the same
process above if we access "page" again. The flush_ptrace_access()
function (borrowed from SPARC64 implementation) is added to handle
cache flushing after memcpy() for the copy_to_user_page() case.

[PATCH] fix NUMA interleaving for huge pages
Since vma->vm_pgoff is in units of smallpages, VMAs for huge pages have the
lower HPAGE_SHIFT - PAGE_SHIFT bits always cleared, which results in badd
offsets to the interleave functions. Take this difference from small pages
into account when calculating the offset. This does add a 0-bit shift into
the small-page path (via alloc_page_vma()), but I think that is negligible.
Also add a BUG_ON to prevent the offset from growing due to a negative
right-shift, which probably shouldn't be allowed anyways.
Tested on an 8-memory node ppc64 NUMA box and got the interleaving I
expected.

[PATCH] sgiioc4: fixup use of mmio ops
Fix some bugs in the patch that converted the IOC4 driver from port IO ops to
memio ops.
http://marc.theaimsgroup.com/?l=linux-ide&m=114895892...
Problems fixed are:
- Call to default_hwif_mmiops() was not being done until _after_
first IO operation, resulting in the first IO operation being
done as a port IO op, instead of memio.
- request_region() calls needed to be request_mem_region()
- Incomplete error case handling.
- Non-usage of ioremap() and __iomem.

[PATCH] powerpc: More via-pmu backlight fixes
The via-pmu backlight code (introduced in 2.6.18) has various design issues
causing crashes on machines using it like the old Wallstreet powerbook
(Michael, the author, never managed to test on these and I just got my hand
on one of those old beasts).
This fixes them by no longer trying to hijack the backlight device of the
frontmost framebuffer (causing that framebuffer to crash) but having it's
own local bits instead. Might look weird but it's better that way on those
old machines, at least as a last-minute fix for 2.6.18. We might rework
the whole thing later. This patch also changes the way it gets notified of
sleep and wakeup in order to properly shut the backlight down on sleep and
bring it back on wakeup.

[PATCH] dm: work around mempool_alloc, bio_alloc_bioset deadlocks
This patch works around a complex dm-related deadlock/livelock down in the
mempool allocator.
Alasdair said:
Several dm targets suffer from this.
Mempools are not yet used correctly everywhere in device-mapper: they can
get shared when devices are stacked, and some targets share them across
multiple instances. I made fixing this one of the prerequisites for this
patch:
md-dm-reduce-stack-usage-with-stacked-block-devices.patch
which in some cases makes people more likely to hit the problem.
There's been some progress on this recently with (unfinished) dm-crypt
patches at:
http://www.kernel.org/pub/linux/kernel/people/agk/patches...
(dm-crypt-move-io-to-workqueue.patch plus dependencies)
and:
I've no problems with a temporary workaround like that, but Milan Broz (a
new Redhat developer in the Czech Republic) has started reviewing all the
mempool usage in device-mapper so I'm expecting we'll soon have a proper fix
for this associated problems. [He's back from holiday at the start of next
week.]
For now, this sad-but-safe little patch will allow the machine to recover.

[PATCH] task delay accounting fixes
Cleanup allocation and freeing of tsk->delays used by delay accounting.
This solves two problems reported for delay accounting:
1. oops in __delayacct_blkio_ticks
http://www.uwsg.indiana.edu/hypermail/linux/kernel/0608.2...
Currently tsk->delays is getting freed too early in task exit which can
cause a NULL tsk->delays to get accessed via reading of /proc/<tgid>/stats.
The patch fixes this problem by freeing tsk->delays closer to when
task_struct itself is freed up. As a result, it also eliminates the use of
tsk->delays_lock which was only being used (inadequately) to safeguard
access to tsk->delays while a task was exiting.
2. Possible memory leak in kernel/delayacct.c
http://www.uwsg.indiana.edu/hypermail/linux/kernel/0608.2...
The patch cleans up tsk->delays allocations after a bad fork which was
missing earlier.
The patch has been tested to fix the problems listed above and stress
tested with rapid calls to delay accounting's taskstats command interface
(which is the other path that can access the same data, besides the /proc
interface causing the oops above).

[PATCH] ZVC: Scale thresholds depending on the size of the system
The ZVC counter update threshold is currently set to a fixed value of 32.
This patch sets up the threshold depending on the number of processors and
the sizes of the zones in the system.
With the current threshold of 32, I was able to observe slight contention
when more than 130-140 processors concurrently updated the counters. The
contention vanished when I either increased the threshold to 64 or used
Andrew's idea of overstepping the interval (see ZVC overstep patch).
However, we saw contention again at 220-230 processors. So we need higher
values for larger systems.
But the current default is already a bit of an overkill for smaller
systems. Some systems have tiny zones where precision matters. For
example i386 and x86_64 have 16M DMA zones and either 900M ZONE_NORMAL or
ZONE_DMA32. These are even present on SMP and NUMA systems.
The patch here sets up a threshold based on the number of processors in the
system and the size of the zone that these counters are used for. The
threshold should grow logarithmically, so we use fls() as an easy
approximation.
Results of tests on a system with 1024 processors (4TB RAM)
The following output is from a test allocating 1GB of memory concurrently
on each processor (Forking the process. So contention on mmap_sem and the
pte locks is not a factor):
X MIN
TYPE: CPUS WALL WALL SYS USER TOTCPU
fork 1 0.552 0.552 0.540 0.012 0.552
fork 4 0.552 0.548 2.164 0.036 2.200
fork 16 0.564 0.548 8.812 0.164 8.976
fork 128 0.580 0.572 72.204 1.208 73.412
fork 256 1.300 0.660 310.400 2.160 312.560
fork 512 3.512 0.696 1526.836 4.816 1531.652
fork 1020 20.024 0.700 17243.176 6.688 17249.863
So a threshold of 32 is fine up to 128 processors. At 256 processors contention
becomes a factor.
Overstepping the counter (earlier patch) improves the numbers a bit:
fork 4 0.552 0.548 2.164 0.040 2.204
fork 16 0.552 0.548 8.640 0.148 8.788
fork 128 0.556 0.548 69.676 0.956 70.632
fork 256 0.876 0.636 212.468 2.108 214.576
fork 512 2.276 0.672 997.324 4.260 1001.584
fork 1020 13.564 0.680 11586.436 6.088 11592.523
Still contention at 512 and 1020. Contention at 1020 is down by a third.
256 still has a slight bit of contention.
After this patch the counter threshold will be set to 125 which reduces
contention significantly:
fork 128 0.560 0.548 69.776 0.932 70.708
fork 256 0.636 0.556 143.460 2.036 145.496
fork 512 0.640 0.548 284.244 4.236 288.480
fork 1020 1.500 0.588 1326.152 8.892 1335.044

[PATCH] ZVC: Overstep counters
Increments and decrements are usually grouped rather than mixed. We can
optimize the inc and dec functions for that case.
Increment and decrement the counters by 50% more than the threshold in
those cases and set the differential accordingly. This decreases the need
to update the atomic counters.
The idea came originally from Andrew Morton. The overstepping alone was
sufficient to address the contention issue found when updating the global
and the per zone counters from 160 processors.
Also remove some code in dec_zone_page_state.

USB: Add VIA quirk fixup for VT8235 usb2
Patch to add VIA PCI quirk for Enhanced/Extended USB on VT8235
southbridge. It is needed in order to use EHCI/USB 2.0 with ACPI.
Without it IRQs are not routed correctly, you get an "Unlink after

usb gadget: g_ether spinlock recursion fix
The new spinlock debug code turned up a spinlock recursion bug in the
Ethernet gadget driver on a disconnect path; it would show up with any
UDC driver where the cancellation of active requests was synchronous,
rather than e.g. delayed until a controller's completion IRQ.
That recursion is fixed here by creating and using a new spinlock to
protect the relevant lists.

IB/mthca: Use IRQ safe locks to protect allocation bitmaps
It is supposed to be OK to call mthca_create_ah() and mthca_destroy_ah()
from any context. However, for mem-full HCAs, these functions use the
mthca_alloc() and mthca_free() bitmap helpers, and those helpers use
non-IRQ-safe spin_lock() internally. Lockdep correctly warns that
this could lead to a deadlock. Fix this by changing mthca_alloc() and
mthca_free() to use spin_lock_irqsave().

[ARM] 3763/1: add both rtcs to csb337 defconfig
Patch from David Brownell
This adds RTC support to the csb337 default config. Both the AT91
and the ds1307 RTCs are enabled (rtc0 and rtc1 respectively).
The ds1307 is used to initialize the system time, since it's battery-backed.
From then on the AT91 RTC is used, since it's more capable (with both
alarm and update irqs, and system wakeup capability) even though it
needs manual initialization (symlink /dev/rtc to /dev/rtc0 for older
versions of hwclock, then "hwclock --systohc") in an rc script or
from inittab.

[PATCH] ppc32: fix last_jiffy time comparison
This fixes a hang on ppc32.
The problem was that I was comparing a 32-bit quantity with a 64-bit
quantity, and consequently time wasn't advancing. This makes us use a
64-bit quantity on all platforms, which ends up simplifying the code
since we can now get rid of the tb_last_stamp variable (which actually
fixes another bug that Ben H and I noticed while going carefully through
the code).
This works fine on my G4 tibook. Let me know how it goes on your

[PATCH] Missing PCI id update for VIA IDE
The following change from -mm is important to 2.6.18 (actually to 2.6.17
but its too late for that). This was contributed over three months ago
by VIA to Bartlomiej and nothing happened. As a result the new chipset
is now out and Linux won't run on it. By the time 2.6.18 is finalised
this will be the defacto standard VIA chipset so support would be a good
plan.
Tested in -mm for a while, its essentially a PCI ident update but for
the bridge chip because VIA do things in weird ways.

[PATCH] x86: Make backtracer fallback logic more bullet-proof
The unwinder fallback logic still had potential for falling through to
the legacy stack trace code without printing an indication (at once
serving as a separator) of this.
Further, the stack pointer retrieval for the fallback should be as
restrictive as possible (in order to avoid having the legacy stack
tracer try to access invalid memory). The patch tightens that, but
this could certainly be further improved.
Also making the call_trace command line option now conditional upon
CONFIG_STACK_UNWIND (as it's meaningless otherwise).

[PATCH] x86: Revert e820 MCFG heuristics
The check for the MCFG table being reserved in the e820 map was originally
added to detect a broken BIOS in a preproduction Intel SDV. However it also
breaks the Apple x86 Macs, which can't supply this properly, but need
a working MCFG. With this patch they wouldn't use the MCFG and not work.
After some discussion I think it's best to remove the heuristic again.
It also failed on some other boxes (although it didn't cause much
problems there because old style port access for PCI config space
still works as fallback), but the preproduction SDVs can just use
pci=nommcfg. Supporting production machines properly is more
important.
Edgar Hucek did all the debugging work.

[POWERPC] Fix irq enable/disable in smp_generic_take_timebase
Eran Ben-Avi <eranpublic@yahoo.com> pointed out that the arch/ppc version
of smp_generic_take_timebase disables interrupts on entry but exits without
restoring them. However, both it and the arch/powerpc version have another
problem, which is that they use local_irq_disable/enable rather than
local_irq_save/restore, and they are called with interrupts disabled.
This fixes both problems; it changes a return to a break in the arch/ppc
version, and changes both versions to use local_irq_save/restore.

[POWERPC] Fix problem with time not advancing on 32-bit platforms
This fixes a problem introduced in 5db9fa9593e2ff69f2b95f9d59229dc4faaa564d.
The last_jiffy per-cpu variable is only 32 bits on 32-bit machines, but it
was being compared with a 64-bit quantity (tb_next_jiffy), which resulted in
time not advancing.
This fixes it by changing last_jiffy to be 64 bits on all platforms. With
this, we no longer need tb_last_stamp as a 32-bit version of tb_last_jiffy,
so this gets rid of tb_last_stamp and we just use tb_last_jiffy instead.
This also fixes a bug when the boot cpu is not online, because using
tb_last_stamp could have caused the wrong timebase origin value to be used
when calculating the time of day.

[POWERPC] Support for "weird" MPICs and fixup mpc7448_hpc2
This adds a new hardware information table for mpic. This enables
the mpic code to deal with mpic controllers with different register
layouts and hardware behaviours.
This introduces CONFIG_MPIC_WEIRD. For boards with non standard mpic
controllers, select CONFIG_MPIC_WEIRD and add its hardware information
in the mpic_infos[] array.
TSI108/109 PIC takes the first index of weird hardware information
table. :) The table can be extended. The Tsi108/109 PIC looks like
standard OpenPIC but, in fact, is different in register mapping and
behavior.
The patch does not affect the behavior of standard mpic. If
CONFIG_MPIC_WEIRD is not defined, the code is essentially identical to
the current code.
[benh@kernel.crashing.org:
This patch is a slightly cleaned up version of Zang Roy's support for
the TSI108 MPIC variant. It also fixes up MPC7448_hpc2 to use the new
version of the type macros and changes the way MPIC is selected in
Kconfig to better match what is done for other system devices.

[SPARC64]: Fix X server hangs due to large pages.
This problem was introduced by changeset
14778d9072e53d2171f66ffd9657daff41acfaed
Unlike the hugetlb code paths, the normal fault code is not setup to
propagate PTE changes for large page sizes correctly like the ones we
make for I/O mappings in io_remap_pfn_range().
It is absolutely necessary to update all sub-ptes of a largepage
mapping on a fault. Adding special handling for this would add
considerably complexity to tlb_batch_add(). So let's just side-step
the issue and forcefully dirty any writable PTEs created by
io_remap_pfn_range().
The only other real option would be to disable to large PTE code of
io_remap_pfn_range() and we really don't want to do that.
Much thanks to Mikael Pettersson for tracking down this problem and
testing debug patches.

[IPV6]: ipv6_add_addr should install dstentry earlier
ipv6_add_addr allocates a struct inet6_ifaddr and a dstentry, but it
doesn't install the dstentry in ifa->rt until after it releases the
addrconf_hash_lock. This means other CPUs will be able to see the new
address while it hasn't been initialized completely yet.
One possible fix would be to grab the ifp->lock spinlock when
creating the address struct; a simpler fix is to just move the
assignment.

[IA64] remove redundant local_irq_save() calls from sn_sal.h
sn_change_memprotect() does a local_irq_save() then calls
ia64_sal_oemcall_nolock() which calls SAL_CALL_NOLOCK()
which also does a local_irq_save().
This patch removes the redundant local_irq_save() and local_irq_restore()
calls in sn_change_memprotect() and sn_inject_error().

[ARM] 3761/1: fix armv4t breakage after adding thumb interworking to userspace helpers
Patch from Lennert Buytenhek
On armv4t systems, we have always compiled the kernel with -march=armv4
instead of -march=armv4t, which means that any use of bx will bomb out.
Commit ba9b5d76372dc290b6ca04dad93927a22c2ac49a introduced the use of
bx in the kernel, which means we need to compile with -march=armv4t on
armv4t systems now.

[IA64] panic if topology_init kzalloc fails
There really is no sense trying to continue if the kzalloc of sysfs_cpus[]
fails in ia64 topology_init. The code calling into here doesn't check
errors very well, and one ends up with a nonobvious boot failure that
wastes peoples time debugging.
See for example the lkml thread at:
http://lkml.org/lkml/2006/3/2/215
Since the system is totally dead when this kzalloc fails, not having yet
even booted, might as well announce one's death boldly and plainly.

[IA64-SGI] Silent data corruption caused by XPC V2.
Jack Steiner identified a problem where XPC can cause a silent
data corruption. On module load, the placement may cause the
xpc_remote_copy_buffer to span two physical pages. DMA transfers are
done to the start virtual address translated to physical.
This patch changes the buffer from a statically allocated buffer to a
kmalloc'd buffer. Dean Nelson reviewed this before posting. I have
tested it in the configuration that was showing the memory corruption
and verified it works. I also added a BUG_ON statement to help catch
this if a similar situation is encountered.
