Active DP dongles return no EDID when dongle

Current driver behavior does not remove the

a gap between dongle DTP and dongle behavior.

For active DP dongles and non-DP scenario,
disconnect sink on detection when no EDID

 "The three SEV commits are not really urgent material. But we figured

  The idea is that the tip, kvm etc branches for 5.14 will all base

  changes are purely mechanical and defines movement so they should be
  fine to go now (famous last words).

Pull io_uring fixes from Jens Axboe:
 "Just a few minor fixes/changes:

   - Fix issue with double free race for linked timeout completions

   - Fix reference issue with timeouts

   - Remove last few places that make SQPOLL special, since it's just an
     io thread now.

   - Bump maximum allowed registered buffers, as we don't allocate as
     much anymore"

  io_uring: increase max number of reg buffers

Pull erofs fixes from Gao Xiang:
 "This mainly fixes 1 lcluster-sized pclusters for the big pcluster
  feature, which can be forcely generated by mkfs as a specific on-disk
  case for per-(sub)file compression strategies but missed to handle in
  runtime properly.

  Also, documentation updates are included to fix the broken
  illustration due to the ReST conversion by accident and complete the
  big pcluster introduction.

  Summary:

   - update documentation to fix the broken illustration due to ReST
     conversion by accident at that time and complete the big pcluster
     introduction

   - fix 1 lcluster-sized pclusters for the big pcluster feature"

 "A fix for a hang condition due to missed wakeups in the filesystem-dax
  core when exercised by virtiofs.

  This bug has been there from the beginning, but the condition has
  not triggered on other filesystems since they hold a lock over
  invalidation events"

Pull more drm fixes from Dave Airlie:
 "Looks like I wasn't the only one not fully switched on this week. The
  msm pull has a missing tag so I missed it, and i915 team were a bit
  late. In my defence I did have a day with the roof of my home office
  removed, so was sitting at my kids desk.

  msm:
   - dsi regression fix
   - dma-buf pinning fix
   - displayport fixes

iomap_max_page_shift is expected to contain a page shift, so it can't be a
'bool', has to be an 'unsigned int'

And fix the default values: P4D_SHIFT is when huge iomap is allowed.

However, on some architectures (eg: powerpc book3s/64), P4D_SHIFT is not a
constant so it can't be used to initialise a static variable.  So,
initialise iomap_max_page_shift with a maximum shift supported by the
architecture, it is gated by P4D_SHIFT in vmap_try_huge_p4d() anyway.
