Pull audit updates from Eric Paris:
"So this change across a whole bunch of arches really solves one basic
problem. We want to audit when seccomp is killing a process. seccomp
hooks in before the audit syscall entry code. audit_syscall_entry
took as an argument the arch of the given syscall. Since the arch is
part of what makes a syscall number meaningful it's an important part
of the record, but it isn't available when seccomp shoots the
syscall...

For most arch's we have a better way to get the arch (syscall_get_arch)
So the solution was two fold: Implement syscall_get_arch() everywhere
there is audit which didn't have it. Use syscall_get_arch() in the
seccomp audit code. Having syscall_get_arch() everywhere meant it was
a useless flag on the stack and we could get rid of it for the typical
syscall entry.

The other changes inside the audit system aren't grand, fixed some
records that had invalid spaces. Better locking around the task comm
field. Removing some dead functions and structs. Make some things
static. Really minor stuff"

The emu10k1 voice allocator takes voice_lock spinlock. When there is
no empty stream available, it tries to release a voice used by synth,
and calls get_synth_voice. The callback function,
snd_emu10k1_synth_get_voice(), however, also takes the voice_lock,
thus it deadlocks.

The fix is simply removing the voice_lock holds in
snd_emu10k1_synth_get_voice(), as this is always called in the
spinlock context.

The Exynos System-on-Chips have ~7 distinctive I2C IO ports (exact
number depends on chip). However some integrated circuits on board, also
using I2C protocol for communication, can be connected to the SoC by
other GPIO. Enabling the I2C GPIO driver allows using such additional
integrated circuits.

An example of such chip using I2C and connected over GPIO to SoC is

This fix is needed for decoupling suspend/resume and advanced
cpuidle support on Exynos platform (next patch fixes build for
config with CONFIG_PM_SLEEP=n and CONFIG_ARM_EXYNOS_CPUIDLE=y).

If this fix is not present then the following OOPS happens on
the first attempt to go into advanced cpuidle mode (AFTR):

Pull sparc fixes from David Miller:
"Here we have two bug fixes:

1) The current thread's fault_code is not setup properly upon entry to
do_sparc64_fault() in some paths, leading to spurious SIGBUS.

2) Don't use a zero length array at the end of thread_info on sparc64,
otherwise end_of_stack() isn't right"

In ib_uverbs_open_qp, the sharable xrc target qp is created as a
"pseudo" qp and added to a list of qp's sharing the same physical
QP. This is done before the "pseudo" qp is assigned a uobject.

There is a race condition here if an async event arrives at the
physical qp. If the event is handled after the pseudo qp is added to
the list, but before it is assigned a uobject, the kernel crashes in
ib_uverbs_qp_event_handler, due to trying to dereference a NULL
uobject pointer.

Note that simply checking for non-NULL is not enough, due to error
flows in ib_uverbs_open_qp. If the failure is after assigning the
uobject, but before the qp has fully been created, we still have a
problem.

Thus, in ib_uverbs_qp_event_handler, we test that the uobject is
present, and also that it is live.

Expose more signature setting parameters. We modify the signature API
to allow usage of some new execution parameters relevant to data
integrity feature.

This patch modifies ib_sig_domain structure by:

- Deprecate DIF type in signature API (operation will
be determined by the parameters alone, no DIF type awareness)
- Add APPTAG check bitmask (for input domain)
- Add REFTAG remap (increment) flag for each domain
- Add APPTAG/REFTAG escape options for each domain

The mlx5 driver is modified to follow the new parameters in HW
signature setup.

At the moment the callers (iser/isert) hard-code new parameters (by
DIF type). In the future, callers will retrieve them from the scsi
command structure.

This patch fixes a failure to open PCM device with -ENOSYS in
Terratec Phase 88.

Terratec Phase 88 has two Selector Function Blocks of AVC Audio subunit
to switch source of clock. One is to switch internal/external for the
source and another is to switch word/spdif for the external clock.

The IDs for these Selector Function Blocks are 9 and 8. But in current
implementation they're 0 and 0.
