      drm/radeon: Inline drm_get_pci_dev · eb12c957
      Daniel Vetter authored 
      It's the last user, and more importantly, it's the last non-legacy
user of anything in drm_pci.c.

The only tricky bit is the agp initialization. But a close look shows
that radeon does not use the drm_agp midlayer (the main use of that is
drm_bufs for legacy drivers), and instead could use the agp subsystem
directly (like nouveau does already). Hence we can just pull this in
too.

A further step would be to entirely drop the use of drm_device->agp,
but feels like too much churn just for this patch.

    drm/amdgpu: drop deprecated drm_get_pci_dev and drm_put_dev

No idea whether this was intentional or accidental breakage, but I
guess anyone who manages to boot a this modern gpu behind an agp
bridge deserves a price. A price I never expect anyone to ever collect
:-)

      drm/i915/gt: Avoid resetting ring->head outside of its timeline mutex · 15de9cb5
      Chris Wilson authored 
      We manipulate ring->head while active in i915_request_retire underneath
the timeline manipulation. We cannot rely on a stable ring->head outside
of the timeline->mutex, in particular while setting up the context for
resume and reset.

      drm/i915/execlists: Always force a context reload when rewinding RING_TAIL · b1339eca
      Chris Wilson authored 
      If we rewind the RING_TAIL on a context, due to a preemption event, we
must force the context restore for the RING_TAIL update to be properly
handled. Rather than note which preemption events may cause us to rewind
the tail, compare the new request's tail with the previously submitted
RING_TAIL, as it turns out that timeslicing was causing unexpected
rewinds.

    page-flags: define PG_reserved behavior on compound pages

    As far as I can see there's no users of PG_reserved on compound pages.
    Let's use PF_NO_COMPOUND here.

drm_pci_alloc has been declared broken since it mixes GFP_COMP and
SetPageReserved. Avoid this conflict by weaning ourselves off using the
abstraction and using the dma functions directly.

      Pull scheduler fixes from Ingo Molnar:
 "Misc fixes all over the place:

   - Fix NUMA over-balancing between lightly loaded nodes. This is
     fallout of the big load-balancer rewrite.

   - Fix the NOHZ remote loadavg update logic, which fixes anomalies
     like reported 150 loadavg on mostly idle CPUs.

   - Fix XFS performance/scalability

   - Fix throttled groups unbound task-execution bug

   - Fix PSI procfs boundary condition

   - Fix the cpu.uclamp.{min,max} cgroup configuration write checks

   - Fix DocBook annotations

   - Fix RCU annotations

   - Fix overly CPU-intensive housekeeper CPU logic loop on large CPU
     counts"

  sched/fair: Fix kernel-doc warning in attach_entity_load_avg()
  sched/core: Annotate curr pointer in rq with __rcu
  sched/psi: Fix OOB write when writing 0 bytes to PSI files
  sched/fair: Allow a per-CPU kthread waking a task to stack on the same CPU, to fix XFS performance regression
  sched/fair: Prevent unlimited runtime on throttled group
  sched/nohz: Optimize get_nohz_timer_target()
  sched/uclamp: Reject negative values in cpu_uclamp_write()
  sched/fair: Allow a small load imbalance between low utilisation SD_NUMA domains
  timers/nohz: Update NOHZ load in remote tick

 "Fixes and HW enablement patches:

   - Tooling fixes, most of which are tooling header synchronization
     with v5.6 changes

   - Fix kprobes fallout on ARM

   - Add Intel Elkhart Lake support and extend Tremont support, these
     are relatively simple and should only affect those models

   - Fix the AMD family 17h generic event table"
