Commit 63d63cbf "NFSv4.1: Don't recheck delegations that
have already been checked" introduced a regression where when a
client received BAD_STATEID error it would not send any TEST_STATEID
and instead go into an infinite loop of resending the IO that caused
the BAD_STATEID.

On this Dell AIO machine, the lineout jack does not work.

We found the pin 0x1a is assigned to lineout on this machine, and in
the past, we applied ALC298_FIXUP_DELL1_MIC_NO_PRESENCE to fix the
heaset-set mic problem for this machine, this fixup will redefine
the pin 0x1a to headphone-mic, as a result the lineout doesn't
work anymore.

After consulting with Dell, they told us this machine doesn't support
microphone via headset jack, so we add a new fixup which only defines
the pin 0x18 as the headset-mic.

[rearranged the fixup insertion position by tiwai in order to make the
 merge with other branches easier -- tiwai]

As reported in STAR 9001165532, an SLC control reg read (for checking
busy state) right after SLC invalidate command may incorrectly return
NOT busy causing software to NOT spin-wait while operation is underway.
(and for some reason this only happens if L1 cache is also disabled - as
required by IOC programming model)

Suggested workaround is to do an additional Control Reg read, which
ensures the 2nd read gets the right status.

ASoC: Fixes for v4.11

A relatively large pile of fixes for mainline, the first since the merge
window.  The biggest block of changes here by volume is the sun8i-codec
set, the driver was newly added in the merge window but it was realized
that renaming some of the user visible controls was required so these
are being pushed for v4.11 to avoid the original code appearing in a
release.  Otherwise it's all fairly standard bugfix stuff.

Upong receiving some errors (EACCES) on commit to the DS the code
doesn't fallback to MDS and intead retrieds to the same DS again.

Commit 5c492c3f ("arm64: smp: Add function to determine if cpus are
stuck in the kernel") added a helper function to determine if die() is
supported in cpu_ops. This function assumes a cpu will have a valid
cpu_ops entry, but that may not be the case for cpu0 is spin-table or
parking protocol is used to boot secondary cpus. In that case, there
is a NULL dereference if have_cpu_die() is called by cpu0. So add a
check for a valid cpu_ops before dereferencing it.

Commit a544c619 ("HID: wacom: do not attempt to switch mode
while in probe") introduces delayed work for querying (setting the
mode) on all tablets. Bamboo Touch (056a:00d0) has a ghost
interface which claims to be a pen device. Though this device can
be removed, we have to set the mode on the ghost pen interface
before we remove it. After the aforementioned delay was introduced
the device was being removed before the mode setting could be
executed.

A previous commit (below) adds a check for already probed interfaces to
Wacom's matching heuristic. Unfortunately this causes the Bamboo Pen
(CTL-460) to match itself to its 'ghost' touch interface. After
subsequent changes to the driver this match to the ghost causes the
kernel to crash. This patch avoids calling wacom_add_shared_data()
for the BAMBOO_PEN's ghost touch interface.

Merge PTRACE_SETREGSET leakage fixes from Dave Martin:
 "This series is the collection of fixes I proposed on this topic, that
  have not yet appeared upstream or in the stable branches,

  The issue can leak kernel stack, but doesn't appear to allow userspace
  to attack the kernel directly.  The affected architectures are c6x,
  h8300, metag, mips and sparc.

  [ Mark Salter points out that c6x has no MMU or other mechanism to
    prevent userspace access to kernel code or data on c6x, but it
    doesn't hurt to clean that case up too. ]

  The bugs arise from use of user_regset_copyin(). Users of
  user_regset_copyin() can work in one of two ways:

   1) Copy directly to thread_struct or equivalent. (This seems to be
      the design assumption of the regset API, and is the most common
      approach.)

   2) Copy to a local variable and then transfer to thread_struct. (A
      significant minority of cases.)

  Buggy code typically involves approach 2"

It's not clear what behaviour is sensible when doing partial write of
NT_METAG_RPIPE, so just don't bother.

This patch assumes that userspace will never rely on a partial SETREGSET
in this case, since it's not clear what should happen anyway.
