handle_percpu_devid_irq() can do all that it was supposed to do. Get rid of
it.

handle_percpu_devid_fasteoi_ipi() states:

 * The biggest difference with the IRQ version is that the interrupt is
 * EOIed early, as the IPI could result in a context switch, and we need to
 * make sure the IPI can fire again

All that can actually happen scheduler-wise within the handling of an IPI
is the raising of TIF_NEED_RESCHED (and / or folding thereof into
preempt_count); see scheduler_ipi() or sched_ttwu_pending() for instance.

Said flag / preempt_count is evaluated some time later before returning to
whatever context was interrupted, and this gates a call to
preempt_schedule_irq() (arm64_preempt_schedule_irq() in arm64).

Per the above, SGI's do not need a different handler than PPI's, so make
them use the same (handle_percpu_devid_irq).

Pull virtual digital TV driver fixes from Mauro Carvalho Chehab:
 "A series of fixes for the new virtual digital TV driver (vidtv), which
  is meant to help doing tests with the digital TV core and media
  userspace apps and libraries.

  They cover a series of issues I found on it, together with a few new
  things in order to make it easier to detect problems at the DVB core"

Pull drm fixes from Dave Airlie:
 "Unfortunately this has a bit of thanksgiving stuffing in it, as it a
  bit larger (at least the vc4 patches) than I like at this point in
  time.

  The main thing is it has a bunch of regressions fixes for reports in
  the last couple of weeks, ast, nouveau and the amdgpu ttm init fix,
  along with the usual selection of amdgpu and i915 fixes.

  The vc4 fixes are a few but they are fixes and the nastiest one is a
  fix for when you have a 2.4Ghz Wifi and a HDMI signal with a clock in
  that range and there isn't enough shielding and interference happen
  between the two, the fix adjusts the mode clock to try and avoid the
  wifi channels in that case.

  Hopefully you can merge this between turkey slices, and next week
  should be quieter.

  ast:
   - LUT loading regression fix

  nouveau:
   - relocations regression fix

  amdgpu:
   - ttm init oops fix
   - Runtime pm fix
   - SI UVD suspend/resume fix
   - HDCP fix for headless cards
   - Sienna Cichlid golden register update

  i915:
   - Fix Perf/OA workaround register corruption (Lionel)
   - Correct a comment statement in GVT (Yan)
   - Fix GT enable/disable iterrupts, including a race condition that
     prevented GPU to go idle (Chris)
   - Free stale request on destroying the virtual engine (Chris)

  exynos:
   - config dependency fix

  mediatek:
   - unused var removal
   - horizonal front/back porch formula fix

  vc4:
   - wifi and hdmi interference fix
   - mode rejection fixes
   - use after free fix
   - cleanup some code"

Merge tag 'linux-can-fixes-for-5.10-20201127' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can

Marc Kleine-Budde says:

====================
pull-request: can 2020-11-27

The first patch is by me and target the gs_usb driver and fixes the endianess
problem with candleLight firmware.

Another patch by me for the mcp251xfd driver add sanity checking to bail out if
no IRQ is configured.

The next three patches target the m_can driver. A patch by me removes the
hardcoded IRQF_TRIGGER_FALLING from the request_threaded_irq() as this clashes
with the trigger level specified in the DT. Further a patch by me fixes the
nominal bitiming tseg2 min value for modern m_can cores. Pankaj Sharma's patch
add support for cores version 3.3.x.

The last patch by Oliver Hartkopp is for af_can and converts a WARN() into a
pr_warn(), which is triggered by the syzkaller. It was able to create a
situation where the closing of a socket runs simultaneously to the notifier
call chain for removing the CAN network device in use.
