The asm-generic/bug.h __ASSEMBLY__ guarding is completely bogus, which
tripped up the powerpc build when the kernel.h include was added:
In file included from include/asm-generic/bug.h:5:0,
from arch/powerpc/include/asm/bug.h:127,
from arch/powerpc/kernel/head_64.S:31:
include/linux/kernel.h:44:0: warning: "ALIGN" redefined [enabled by default]
include/linux/linkage.h:57:0: note: this is the location of the previous definition
include/linux/sysinfo.h: Assembler messages:
include/linux/sysinfo.h:7: Error: Unrecognized opcode: `struct'
include/linux/sysinfo.h:8: Error: Unrecognized opcode: `__kernel_long_t'
Moving the __ASSEMBLY__ guard up and stashing the kernel.h include under
it fixes this up, as well as covering the case the original fix was
attempting to handle.

When the READABLE_ASM cc-option tests were added they were done so prior
to the arch Makefile include, resulting in cc-option being run on the
host cc instead of the factoring in the cross prefix set up by the
architecture.
This bumps the include back up so that cc-option actually runs on the
compiler that we're building with.

Commit 5963e317b1e9d2a ("ftrace/x86: Do not change stacks in DEBUG when
calling lockdep") prevented lockdep calls from the int3 breakpoint handler
from reseting the stack if a function that was called was in the process
of being converted for tracing and had a breakpoint on it. The idea is,
before calling the lockdep code, do a load_idt() to the special IDT that
kept the breakpoint stack from reseting. This worked well as a quick fix
for this kernel release, until a certain config caused a lockup in the
function tracer start up tests.
Investigating it, I found that the load_idt that was used to prevent
the int3 from changing stacks was itself being traced!
Even though the config had CONFIG_OPTIMIZE_INLINING disabled, and
all 'inline' tags were set to always inline, there were still cases that
it did not inline! This was caused by CONFIG_PARAVIRT_GUEST, where it
would add a pointer to the native_load_idt() which made that function
to be traced.
Commit 45959ee7aa645815a ("ftrace: Do not function trace inlined functions")
only touched the 'inline' tags when CONFIG_OPMITIZE_INLINING was enabled.
PARAVIRT_GUEST shows that this was not enough and we need to also
mark always_inline with notrace as well.

Currently there is a 'chicken and egg' issue when the DS is also the mounted
MDS. The nfs_match_client() reference from nfs4_set_ds_client bumps the
cl_count, the nfs_client is not freed at umount, and nfs4_deviceid_purge_client
is not called to dereference the MDS usage of a deviceid which holds a
reference to the DS nfs_client. The result is the umount program returns,
but the nfs_client is not freed, and the cl_session hearbeat continues.
The MDS (and all other nfs mounts) lose their last nfs_client reference in
nfs_free_server when the last nfs_server (fsid) is umounted.
The file layout DS lose their last nfs_client reference in destroy_ds
when the last deviceid referencing the data server is put and destroy_ds is
called. This is triggered by a call to nfs4_deviceid_purge_client which
removes references to a pNFS deviceid used by an MDS mount.
The fix is to track how many pnfs enabled filesystems are mounted from
this server, and then to purge the device id cache once that count reaches
zero.

Each file in the 'events' directory defines a event alias. Its contents

We want to reuse the event grammar for parsing aliased terms.
The obvious reason is we dont need to add new code when there's
already support for this in event grammar.
Doing this by adding terms and event start entries into event
parse grammar. The grammar forks on the begining based on the
starting token, which is supplied via bison interface into the
lexer. The lexer then returns the starting token as the first
token, thus making the grammar switch accordingly.
Currently 2 starting tokens/grammars are supported:
PE_START_TERMS, PE_START_EVENTS
The PE_START_TERMS related grammar uses 'event_config' part
of the grammar for term parsing.

This patch adds the generic Intel uncore PMU support, including helper
functions that add/delete uncore events, a hrtimer that periodically
polls the counters to avoid overflow and code that places all events
for a particular socket onto a single cpu.
The code design is based on the structure of Sandy Bridge-EP's uncore
subsystem, which consists of a variety of components, each component
contains one or more "boxes".
(Tooling support follows in the next patches.)

An rmdir pushes css's ref count to zero. However, if the associated
directory is open at the time, the dentry ref count is non-zero. If
the fd for this directory is then passed into perf_event_open, it
does a css_get(). This bounces the ref count back up from zero. This
is a problem by itself. But what makes it turn into a crash is the
fact that we end up doing an extra dput, since we perform a dput
when css_put sees the ref count go down to zero.
css_tryget() does not fall into that trap. So, we use that instead.

Commit 8637e38a ("x86/apic: Avoid useless scanning thru a
cpumask in assign_irq_vector()") modified
vector_allocation_domain() to return a boolean indicating if
cpumask is dynamic or static. Adjust vSMP's callback
implementation accordingly.

This addresses an issue encountered when a pcm is opened while
transitioning to low power state (codec->power_on == 1 &&
codec->power_transition == -1). Add snd_pcm_power_up_d3wait to
hda_codec. This function is used to power up from azx_open as opposed
to snd_hda_power_up used from codec_exec_verb. When powering up from
azx_open, wait for pending power downs to complete, avoiding the power
up continuing in parallel with the power down on the work queue.
The specific issue seen was with the CS4210 codec, it powers off the ADC
and DAC nid in its suspend handler. If it is re-opened before the
~100ms power down process completes, the ADC and DAC nid are initialized
while powered down and audio is lost until another suspend/resume cycle.

Fix a bogus sanity check for sync pipe in pcm.c. This flaw was
introduced during the streaming logic refactorization.
While at it, improve the error messages that are generated in such cases.

ASoC: Updates for 3.5
All driver specific and fairly small. The pxa-ssp changes are larger
than I'd like but they're build failures and are pretty clear to
inspection.

There are four link statuses of a bonding slave, the procfs
code shows a wrong status when using downdelay/updelay:
(slave->link == BOND_LINK_UP) ? "up" : "down"
It doesn't respect the rest two statuses. This patch fixes it.
