ARM: 6201/1: RealView: Do not use outer_sync() on ARM11MPCore boards with L220
RealView boards with certain revisions of the L220 cache controller (ARM11*
processors only) may have issues (hardware deadlock) with the recent changes to
the mb() barrier implementation (DSB followed by an L2 cache sync). The patch
redefines the RealView ARM11MPCore mandatory barriers without the outer_sync()
call.

CPU performance event counters on v7 cores will only operate
if either the NIDEN or DBGEN signals are driven high.
For the OMAP3 platform, these signals are driven low by default
but DBGEN can be asserted by selecting the OMAP3_EMU Kconfig option,

ARM: 6194/1: change definition of cpu_relax() for ARM11MPCore
Linux expects that if a CPU modifies a memory location, then that
modification will eventually become visible to other CPUs in the system.
On an ARM11MPCore processor, loads are prioritised over stores so it is
possible for a store operation to be postponed if a polling loop immediately
follows it. If the variable being polled indirectly depends on the outstanding
store [for example, another CPU may be polling the variable that is pending
modification] then there is the potential for deadlock if interrupts are
disabled. This deadlock occurs in the KGDB testsuire when executing on an
SMP ARM11MPCore configuration.
This patch changes the definition of cpu_relax() to smp_mb() for ARMv6 cores,
forcing a flushing of the write buffer on SMP systems before the next load
takes place. If the Kernel is not compiled for SMP support, this will expand
to a barrier() as before.

ARM: 6188/1: Add a config option for the ARM11MPCore DMA cache maintenance workaround
Commit
f4d6477f introduced a workaround for the lack of hardware
broadcasting of the cache maintenance operations on ARM11MPCore.
However, the workaround is only valid on CPUs that do not do speculative
loads into the D-cache.
This patch adds a Kconfig option with the corresponding help to make the
above clear. When the DMA_CACHE_RWFO option is disabled, the kernel
behaviour is that prior to the
f4d6477f commit. This also allows ARMv6
UP processors with speculative loads to work correctly.
For other processors, a different workaround may be needed.

futex: futex_find_get_task remove credentails check
futex_find_get_task is currently used (through lookup_pi_state) from two
contexts, futex_requeue and futex_lock_pi_atomic. None of the paths
looks it needs the credentials check, though. Different (e)uids
shouldn't matter at all because the only thing that is important for
shared futex is the accessibility of the shared memory.
The credentail check results in glibc assert failure or process hang (if
glibc is compiled without assert support) for shared robust pthread
mutex with priority inheritance if a process tries to lock already held
lock owned by a process with a different euid:
pthread_mutex_lock.c:312: __pthread_mutex_lock_full: Assertion `(-(e)) != 3 || !robust' failed.
The problem is that futex_lock_pi_atomic which is called when we try to
lock already held lock checks the current holder (tid is stored in the
futex value) to get the PI state. It uses lookup_pi_state which in turn
gets task struct from futex_find_get_task. ESRCH is returned either
when the task is not found or if credentials check fails.
futex_lock_pi_atomic simply returns if it gets ESRCH. glibc code,
however, doesn't expect that robust lock returns with ESRCH because it
should get either success or owner died.

sense to change it if both convert_src and scan_begin_src are set to
TRIG_TIMER.
Note: 'scan_delay' is the number of unwanted scans to discard after each
valid scan. The hardware does not support 'scan' timing as such, just a
regularly paced conversion timer (with automatic channel switching
between conversions). The driver simulates a scan period that is some
(>1) multiple of the conversion period times the scan length
(chanlist_len samples) by reading chanlist_len samples and discarding
the next scan_delay times chanlist_len samples.

On fsg_unbind the common->fsg pointer was not NULLed if the

which caused do_set_interface to reference an invalid region.
This commit fixes this by raising an exception in fsg_bind

an wait queue so that the thread in fsg_bind can wait till the
worker thread handles the exception.
This commit removes also a config and new_config fields of
fsg_common as they are no longer needed since fsg can be

Moreover, this commit removes possible race condition where
the fsg field was modified in both the worker thread and

prev_fsg with new_fsg. At this point, fsg is assigned only

USB: obey the sysfs power/wakeup setting
This patch (as1403) is a partial reversion of an earlier change
(commit
5f677f1d45b2bf08085bbba7394392dfa586fa8e "USB: fix remote
wakeup settings during system sleep"). After hearing from a user, I
realized that remote wakeup should be enabled during system sleep
whenever userspace allows it, and not only if a driver requests it
too.
Indeed, there could be a device with no driver, that does nothing but
generate a wakeup request when the user presses a button. Such a
device should be allowed to do its job.
The problem fixed by the earlier patch -- device generating a wakeup
request for no reason, causing system suspend to abort -- was also
addressed by a later patch ("USB: don't enable remote wakeup by
default", accepted but not yet merged into mainline). The device
won't be able to generate the bogus wakeup requests because it will be
disabled for remote wakeup by default. Hence this reversion will not
re-introduce any old problems.

USB: xHCI: Fix bug in link TRB activation change.
Commit
6c12db90f19727c76990e7f4801c67a148b30111 introduced a bug for
control transfers. The patch was supposed to change when the link TRBs at
the end of each ring segment were given to the hardware. If a transfer
descriptor (TD) ended just before the link TRB, the code wouldn't give
back the link TRB to the hardware; instead it would be given back in
prepare_ring() just before the next TD was enqueued at the top of the
ring.
Unfortunately, the code relied on checking the chain bit of the TRB to
determine whether the TD ended just before the link TRB. It assumed that
the ring enqueuing code would call prepare_ring() before enqueuing the
next TD. However, control transfers are made of multiple TDs, and
prepare_ring() is only called once before enqueuing two or three TDs.
If the first or second TD of the control transfer ended just before the
link TRB, then the code in inc_enq() would not move the enqueue pointer
past the link TRB, and the link TRB would get overwritten. This would
cause the xHCI driver to start writing to memory past the ring segment,
and eventually the system would crash or hang.
The fix is to add a flag to inc_enq() that says whether the caller will
enqueue more TDs before calling prepare_ring(). If the chain bit is
cleared (meaning this is the last TRB in a TD), and the caller will not
enqueue more TDs, then we defer giving back the link TRB.

mempolicy: fix dangling reference to tmpfs superblock mpol
My patch to "Factor out duplicate put/frees in mpol_shared_policy_init()
to a common return path"; and Dan Carpenter's fix thereto both left a
dangling reference to the incoming tmpfs superblock mempolicy structure.
A similar leak was introduced earlier when the nodemask was moved offstack
to the scratch area despite the note in the comment block regarding the
incoming ref.
Move the remaining 'put of the incoming "mpol" to the common exit path to
drop the reference.

ipmi: make sure drivers were registered before unregistering them
The ipmi code will never register a PCI or Open Firmware driver if a
hardcoded device is provided by the user by providing device addresses via
the module parameters. This can cause us to attempt to unregister a
driver that was never registered, resulting in an oops. Keep track of
registration in order to avoid this.

compiler-gcc.h: gcc-4.5 needs noclone and noinline on __naked functions
A __naked function is defined in C but with a body completely implemented
by asm(), including any prologue and epilogue. These asm() bodies expect
standard calling conventions for parameter passing. Older GCCs implement
that correctly, but 4.[56] currently do not, see GCC PR44290. In the
Linux kernel this breaks ARM, causing most arch/arm/mm/copypage-*.c
modules to get miscompiled, resulting in kernel crashes during bootup.
Part of the kernel fix is to augment the __naked function attribute to
also imply noinline and noclone. This patch implements that, and has been
verified to fix boot failures with gcc-4.5 compiled 2.6.34 and 2.6.35-rc1
kernels. The patch is a no-op with older GCCs.

flat: tweak default stack alignment
The recent commit
1f0ce8b3dd667dca7 ("mm: Move ARCH_SLAB_MINALIGN and
ARCH_KMALLOC_MINALIGN to <linux/slab_def.h>") which moved the
ARCH_SLAB_MINALIGN default into the global header inadvertently broke FLAT
for a bunch of systems. Blackfin systems now fail on any FLAT exec with:
Unable to read code+data+bss, errno 14 When your /init is a FLAT binary,
obviously this can be annoying ;).
This stems from the alignment usage in the FLAT loader. The behavior
before was that FLAT would default to ARCH_SLAB_MINALIGN only if it was
defined, and this was only defined by arches when they wanted a larger
alignment value. Otherwise it'd default to pointer alignment. Arguably,
this is kind of hokey that the FLAT is semi-abusing defines it shouldn't.
So let's merge the two alignment requirements so the floor is never 0.

OOM-waitqueue should be waken up when oom_disable is canceled. This is a

How to test:
Create a cgroup A...
1. set memory.limit and memory.memsw.limit to be small value
2. echo 1 > /cgroup/A/memory.oom_control, this disables oom-kill.
3. run a program which must cause OOM.
A program executed in 3 will sleep by oom_waiqueue in memcg. Then, how to
wake it up is problem.
1. echo 0 > /cgroup/A/memory.oom_control (enable OOM-killer)
2. echo big mem > /cgroup/A/memory.memsw.limit_in_bytes(allow more swap)
