Fix the SELinux netlink_send hook to properly handle multiple netlink
messages in a single sk_buff; each message is parsed and subject to
SELinux access control. Prior to this patch, SELinux only inspected
the first message in the sk_buff.

As it was done in commit 8f659a03a0ba ("net: ipv4: fix for a race
condition in raw_sendmsg") and commit 20b50d79974e ("net: ipv4: emulate
READ_ONCE() on ->hdrincl bit-field in raw_sendmsg()") for ipv4, copy the
value of inet->hdrincl in a local variable, to avoid introducing a race
condition in the next commit.

When registering a ASoC card the driver data of the parent device is set to
point to the card. This driver data is used in the
snd_soc_suspend()/resume() callbacks.
The imx-spdif driver overwrites the driver data with custom data which
causes snd_soc_suspend() to crash. Since the custom driver is not used
anywhere simply deleting the line which sets the custom driver data fixes
the issue.

Ironically, 7d4020c3c400 ("[media] exynos4-is: fix some warnings when
compiling on arm64") fixed some format string bugs but introduced a
new one. buf_index is a simple int, so it should be printed with %d,
not %pad (which is correctly used for dma_addr_t).

When calling intel_alt_er() with .idx != EXTRA_REG_RSP_* we will not
initialize alt_idx and then use this uninitialized value to index an
array.
When that is not fatal, it can result in an infinite loop in its
caller __intel_shared_reg_get_constraints(), with IRQs disabled.
Alternative error modes are random memory corruption due to the
cpuc->shared_regs->regs[] array overrun, which manifest in either
get_constraints or put_constraints doing weird stuff.
Only took 6 hours of painful debugging to find this. Neither GCC nor
Smatch warnings flagged this bug.

Commit 7a7868326d77 ("powerpc/perf: Add an explict flag indicating
presence of SLOT field") introduced the PPMU_HAS_SSLOT flag to remove
the assumption that MMCRA[SLOT] was present when PPMU_ALT_SIPR was not
set.
That commit's changelog also mentions that Power8 does not support
MMCRA[SLOT]. However when the Power8 PMU support was merged, it
errnoeously included the PPMU_HAS_SSLOT flag.
So remove PPMU_HAS_SSLOT from the Power8 flags.
mpe: On systems where MMCRA[SLOT] exists, the field occupies bits 37:39
(IBM numbering). On Power8 bit 37 is reserved, and 38:39 overlap with
the high bits of the Threshold Event Counter Mantissa. I am not aware of
any published events which use the threshold counting mechanism, which
would cause the mantissa bits to be set. So in practice this bug is
unlikely to trigger.

This is effectively reapplies the commit b0898fdaffb2 ("i2c: designware-pci: use
IRQF_COND_SUSPEND flag") after the commit d80d134182ba ("i2c: designware: Move
common probe code into i2c_dw_probe()"). Original message as follows.
The mentioned flag fixes a warning on Intel Edison board since one of the I2C
controller shares IRQ line with watchdog timer.
