Pull scheduler fixes from Thomas Gleixner:
 "A set of scheduler fixes:

   - Plug a load average accounting race which was introduced with a
     recent optimization casing load average to show bogus numbers.

   - Fix the rseq CPU id initialization for new tasks. sched_fork() does
     not update the rseq CPU id so the id is the stale id of the parent
     task, which can cause user space data corruption.

   - Handle a 0 return value of task_h_load() correctly in the load
     balancer, which does not decrease imbalance and therefore pulls
     until the maximum number of loops is reached, which might be all
     tasks just created by a fork bomb"

Pull drm fixes from Dave Airlie:
 "Weekly fixes pull, big bigger than I'd normally like, but they are
  fairly scattered and small individually.

  The vmwgfx one is a black screen regression, otherwise the largest is
  an MST encoder fix for amdgpu which results in a WARN in some cases,
  and a scattering of i915 fixes.

  I'm tracking two regressions at the moment that hopefully we get
  nailed down this week for rc7.

  dma-buf:
   - sleeping atomic fix

  amdgpu:
   - Fix a race condition with KIQ
   - Preemption fix
   - Fix handling of fake MST encoders
   - OLED panel fix
   - Handle allocation failure in stream construction
   - Renoir SMC fix
   - SDMA 5.x fix

  i915:
   - FBC w/a stride fix
   - Fix use-after-free fix on module reload
   - Ignore irq enabling on the virtual engines to fix device sleep
   - Use GTT when saving/restoring engine GPR
   - Fix selftest sort function

Previous patch changed handling of remount/reconfigure to ignore all
options, including those that are unknown to the fuse kernel fs.  This was
done for backward compatibility, but this likely only affects the old
mount(2) API.

The new fsconfig(2) based reconfiguration could possibly be improved.  This
would make the new API less of a drop in replacement for the old, OTOH this
is a good chance to get rid of some weirdnesses in the old API.

Several other behaviors might make sense:

 1) unknown options are rejected, known options are ignored

 2) unknown options are rejected, known options are rejected if the value
 is changed, allowed otherwise

 3) all options are rejected

Prior to the backward compatibility fix to ignore all options all known
options were accepted (1), even if they change the value of a mount
parameter; fuse_reconfigure() does not look at the config values set by
fuse_parse_param().

To fix that we'd need to verify that the value provided is the same as set
in the initial configuration (2).  The major drawback is that this is much
more complex than just rejecting all attempts at changing options (3);
i.e. all options signify initial configuration values and don't make sense
on reconfigure.

This patch opts for (3) with the rationale that no mount options are
reconfigurable in fuse.
