0c32b8ec02 [media] s5p-mfc: Fix race between interrupt routine and device functions
Interrupt routine must wake process waiting for given interrupt AFTER
updating driver's internal structures and contexts. Doing it in-between
is a serious bug. This patch moves all calls to the wake() function to
the end of the interrupt processing block to avoid potential and real
races, especially on multi-core platforms. This also fixes following issue
reported from clock core (clocks were disabled in interrupt after being
unprepared from the other place in the driver, the stack trace however
points to the different place than s5p_mfc driver because of the race):

7c96f59e0c [media] s5p-mfc: Fix initialization of internal structures
Initialize members of the internal device and context structures as early
as possible to avoid access to uninitialized objects on initialization
failures. If loading firmware or creating of the hardware instance fails,
driver will access device or context queue in error handling path, which
might not be initialized yet, what causes kernel panic. Fix this by moving
initialization of all static members as early as possible.

ba40be0fa2 [media] media: mtk-jpeg: fix continuous log "Context is NULL"
The symptom is continuous log "mtk-jpeg 18004000.jpegdec: Context is NULL"
in kernel log. It is because the error handling in irq doesn't clear
interrupt.

The calling flow like as below when issue happen
mtk_jpeg_device_run()
mtk_jpeg_job_abort()
  v4l2_m2m_job_finish() -> m2m_dev->curr_ctx = NULL;
mtk_jpeg_dec_irq()
  v4l2_m2m_get_curr_priv()
     -> m2m_dev->curr_ctx == NULL
     -> return NULL
log "Context is NULL"

There is race condition between job_abort() and irq. In order to simplify
code, don't want to add extra flag to maintain state, empty job_abort() and
clear interrupt before v4l2_m2m_get_curr_priv() in irq.

 "This update provides:

     was added in order to proveide better sched clock continuity

   - switching sched clock to unstable mode runs all clock related
     computations which affect the sched clock output itself from a work
     queue. In case of preemption sched clock uses half updated data and
     provides wrong timestamps. Keep the math in the protected context

346ce1d75c Merge branch 'parisc-4.11-3' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc fixes from Helge Deller:
 "Al Viro reported that - in case of read faults - our copy_from_user()
  implementation may claim to have copied more bytes than it actually
  did. In order to fix this bug and because of the way how gcc optimizes
  register usage for inline assembly in C code, we had to replace our
  pa_memcpy() function with a pure assembler implementation.

  While fixing the memcpy bug we noticed some other issues with our
  get_user() and put_user() functions, e.g. nested faults may return
  wrong data. This is now fixed by a common fixup handler for
  get_user/put_user in the exception handler which additionally makes
  generated code smaller and faster.

  The third patch is a trivial one-line fix for a patch which went in
  during 4.11-rc and which avoids stalled CPU warnings after power
  shutdown (for parisc machines which can't plug power off themselves).

  Due to the rewrite of pa_memcpy() into assembly this patch got bigger
  than what I wanted to have sent at this stage.

  Those patches have been running in production during the last few days
  on our debian build servers without any further issues"

Thirteen small fixes: The hopefully final effort to get the lpfc nvme
 kconfig problems sorted, there's one important sg fix (user can induce
 read after end of buffer) and one minor enhancement (adding an extra
 PCI ID to qedi). The rest are a set of minor fixes, which mostly occur
 as user visible in error legs or on specific devices.
