__sa1111_remove always frees its argument, so the subsequent reference to
sachip->saved_state represents a use after free.  __sa1111_remove does not
appear to use the saved_state field, so the patch simply frees it first.

831e8047eb ARM: 6279/1: highmem: fix SMP preemption bug in kmap_high_l1_vipt
smp_processor_id() must not be called from a preemptible context (this
is checked by CONFIG_DEBUG_PREEMPT).  kmap_high_l1_vipt() was doing so.
This lead to a problem where the wrong per_cpu kmap_high_l1_vipt_depth
could be incremented, causing a BUG_ON(*depth <= 0); in
kunmap_high_l1_vipt().

The solution is to move the call to smp_processor_id() after the call
to preempt_disable().

b92b361213 ARM: Add barriers to io{read,write}{8,16,32} accessors as well

place of readl/writel et.al. in portable drivers.  Create __iormb()

79f64dbf68 ARM: 6273/1: Add barriers to the I/O accessors if ARM_DMA_MEM_BUFFERABLE
When the coherent DMA buffers are mapped as Normal Non-cacheable
(ARM_DMA_MEM_BUFFERABLE enabled), buffer accesses are no longer ordered
with Device memory accesses causing failures in device drivers that do
not use the mandatory memory barriers before starting a DMA transfer.
LKML discussions led to the conclusion that such barriers have to be
added to the I/O accessors:

http://thread.gmane.org/gmane.linux.kernel/683509/focus=686153
http://thread.gmane.org/gmane.linux.ide/46414
http://thread.gmane.org/gmane.linux.kernel.cross-arch/5250

This patch introduces a wmb() barrier to the write*() I/O accessors to
handle the situations where Normal Non-cacheable writes are still in the
processor (or L2 cache controller) write buffer before a DMA transfer
command is issued. For the read*() accessors, a rmb() is introduced
after the I/O to avoid speculative loads where the driver polls for a
DMA transfer ready bit.

This patch is in preparation for a subsequent patch which adds barriers

sync, this patch avoids a recursive call into l2x0_cache_sync() via the

l2x0_lock held.

ba773f7c51 x86,kgdb: Fix hw breakpoint regression
HW breakpoints events stopped working correctly with kgdb
as a result of commit: 018cbffe68
(Merge commit 'v2.6.33' into perf/core).

The regression occurred because the behavior changed for setting
NOTIFY_STOP as the return value to the die notifier if the breakpoint
was known to the HW breakpoint API.  Because kgdb is using the HW
breakpoint API to register HW breakpoints slots, it must also now
implement the overflow_handler call back else kgdb does not get to see
the events from the die notifier.

The kgdb_ll_trap function will be changed to be general purpose code
which can allow an easy way to implement the hw_breakpoint API
overflow call back.

33fea794b9 [S390] etr: fix clock synchronization race
The etr events switch-to-local and sync-check disable the synchronous clock
and schedule a work queue that tries to get the clock back into sync.
If another switch-to-local or sync-check event occurs while the work queue
function etr_work_fn still runs the eacr.es bit and the clock_sync_word can
become inconsistent because check_sync_clock only uses the clock_sync_word
to determine if the clock is in sync or not. The second pass of the
etr_work_fn will reset the eacr.es bit but will leave the clock_sync_word
intact. Fix this race by moving the reset of the eacr.es bit into the
switch-to-local and sync-check functions and by checking the eacr.es bit
as well to decide if the clock needs to be synced.

6b95ed345b perf, powerpc: Use perf_sample_data_init() for the FSL code
We should use perf_sample_data_init() to initialize struct
perf_sample_data.  As explained in the description of commit dc1d628a
("perf: Provide generic perf_sample_data initialization"), it is
possible for userspace to get the kernel to dereference data.raw,
so if it is not initialized, that means that unprivileged userspace
can possibly oops the kernel.  Using perf_sample_data_init makes sure
it gets initialized to NULL.

This conversion should have been included in commit dc1d628a, but it
got missed.

The PCC cpufreq driver unmaps the mailbox address range if any CPUs fail to

cpufreq core resulting in failures further down the line. We're better off
simply returning a failure - the cpufreq core will unregister us cleanly if
we end up with no successfully registered CPUs. Tidy up the failure path
and also add a sanity check to ensure that the firmware gives us a realistic
frequency - the core deals badly with that being set to 0.

47f8bcf362 [CPUFREQ] pcc driver should check for pcch method before calling _OSC
The pcc specification documents an _OSC method that's incompatible with the
one defined as part of the ACPI spec. This shouldn't be a problem as both
are supposed to be guarded with a UUID. Unfortunately approximately nobody
(including HP, who wrote this spec) properly check the UUID on entry to the
_OSC call. Right now this could result in surprising behaviour if the pcc
driver performs an _OSC call on a machine that doesn't implement the pcc
specification. Check whether the PCCH method exists first in order to reduce
this probability.

patch the patch ARM: 6092/1: atmel_serial: support for RS485
communications (e8faff7330)

The build failure was caused by missing struct field and missing defines
for the avr32 board - the patch fixes this.

8faf2e6c20 MIPS: Set io_map_base for several PCI bridges lacking it
Several MIPS platforms don't set pci_controller::io_map_base for their
PCI bridges.  This results in a panic in pci_iomap().  (The panic is
conditional on CONFIG_PCI_DOMAINS, but that is now enabled for all PCI
MIPS systems.)

0d5977d652 MIPS: Alchemy: Define eth platform devices in the correct order
Currently, the eth devices are probed in the inverse order, first
au1xxx_eth1_device and then au1xxx_eth0_device. On the GPR board,
this makes trouble:

  # ifconfig|grep HWaddr
  eth0      Link encap:Ethernet  HWaddr 00:50:C2:0C:30:01
  eth1      Link encap:Ethernet  HWaddr 66:22:01:80:38:10

A bogous ethernet hwaddr is assigned to the first device and
au1xxx_eth0_device is mapped to eth1, which even does not work
properly. With this patch, the problems are gone:

  # ifconfig|grep HWaddr
  eth0      Link encap:Ethernet  HWaddr 66:22:11:32:38:10
  eth1      Link encap:Ethernet  HWaddr 66:22:11:32:38:11

31c984a5ac MIPS: N32: Define getdents64.
As a relativly new ABI N32 should only have received the getdents64(2) but
instead it only had getdents(2).  This was noticed as a performance anomaly
in glibc.

98a0f86a54 MIPS: MTX-1: Fix PCI on the MeshCube and related boards
This patch fixes a regression introduced by commit "MIPS: Alchemy: MTX-1:
Use linux gpio api." (bb706b28bb) which broke
PCI bus operation. The problem is caused by alchemy_gpio2_enable() which
resets the GPIO2 block. Two PCI signals (PCI_SERR and PCI_RST) are connected
to GPIO2 and they obviously do not to like the reset. Since GPIO2 is
correctly initialized by the boot monitor (YAMON) it is not necessary to
call this function, so just remove it.

Also replace gpio_set_value() with alchemy_gpio_set_value() to avoid
problems in case gpiolib gets initialized after PCI. And since alchemy
gpio_set_value() calls au_sync() we don't have to au_sync() again later.

1ed845375b MIPS: Make init_vdso a subsys_initcall.
Quoting from Jiri Slaby's patch of a similar nature for x86:

    When initrd is in use and a driver does request_module() in its
    module_init (i.e. __initcall or device_initcall), a modprobe
    process is created with VDSO mapping. But VDSO is inited even in
    __initcall, i.e. on the same level (at the same time), so it may
    not be inited yet (link order matters).

Move init_vdso up to subsys_initcall to avoid the issue.
