Unfortunately even the HPD based detection added in
commit cfe5bdfb ("drm/i915: Check HPD live state during eDP probe")
fails to detect that the VBT's eDP/DDI-A is a ghost on
Asus B360M-A (CFL+CNP). On that board eDP/DDI-A has its HPD
asserted despite nothing being actually connected there :(
The straps/fuses also indicate that the eDP port is present.

So if one boots with a VGA monitor connected the eDP probe will
mistake the DP->VGA converter hooked to DDI-E for an eDP panel
on DDI-A.

As a last resort check what kind of DP device we've detected,
and if it looks like a DP->VGA converter then conclude that
the eDP port should be ignored.

The GSC CS is not exposed to the user, so we skipped assigning a uabi
class number for it. However, the trace logs use the uabi class and
instance to identify the engine, so leaving uabi class unset makes the
GSC CS show up as the RCS in those logs.

Given that the engine is not exposed to the user, we can't add a new
case in the uabi enum, so we insted internally define a kernel
internal class as -1.

At the same time remove special handling for the name and complete
the uabi_classes array so internal class is automatically correctly
assigned.

Engine will show as 65535:0 other0 in the logs/traces which should
be unique enough.

Fake flexible arrays (zero-length and one-element arrays) are deprecated,
and should be replaced by flexible-array members. So, replace
zero-length array with a flexible-array member in `struct
PACKED_REGISTRY_TABLE`.

Also annotate array `entries` with `__counted_by()` to prepare for the
coming implementation by GCC and Clang of the `__counted_by` attribute.
Flexible array members annotated with `__counted_by` can have their
accesses bounds-checked at run-time via `CONFIG_UBSAN_BOUNDS` (for array
indexing) and `CONFIG_FORTIFY_SOURCE` (for strcpy/memcpy-family functions).

This fixes multiple -Warray-bounds warnings:
drivers/gpu/drm/nouveau/nvkm/subdev/gsp/r535.c:1069:29: warning: array subscript 0 is outside array bounds of 'PACKED_REGISTRY_ENTRY[0]' [-Warray-bounds=]

Pull tracing fixes from Steven Rostedt::
 "Eventfs fixes:

   - With the usage of simple_recursive_remove() recommended by Al Viro,
     the code should not be calling "d_invalidate()" itself. Doing so is
     causing crashes. The code was calling d_invalidate() on the race of
     trying to look up a file while the parent was being deleted. This
     was detected, and the added dentry was having d_invalidate() called
     on it, but the deletion of the directory was also calling
     d_invalidate() on that same dentry.

   - A fix to not free the eventfs_inode (ei) until the last dput() was
     called on its ei->dentry made the ei->dentry exist even after it
     was marked for free by setting the ei->is_freed. But code elsewhere
     still was checking if ei->dentry was NULL if ei->is_freed is set
     and would trigger WARN_ON if that was the case. That's no longer
     true and there should not be any warnings when it is true.

   - Use GFP_NOFS for allocations done under eventfs_mutex. The
     eventfs_mutex can be taken on file system reclaim, make sure that
     allocations done under that mutex do not trigger file system
     reclaim.

   - Clean up code by moving the taking of inode_lock out of the helper
     functions and into where they are needed, and not use the parameter
     to know to take it or not. It must always be held but some callers
     of the helper function have it taken when they were called.

   - Warn if the inode_lock is not held in the helper functions.

   - Warn if eventfs_start_creating() is called without a parent. As
     eventfs is underneath tracefs, all files created will have a parent
     (the top one will have a tracefs parent).

   - Add Mathieu Desnoyers as an official reviewer of the tracing subsystem"

Pull parisc architecture fixes from Helge Deller:
 "This patchset fixes and enforces correct section alignments for the
  ex_table, altinstructions, parisc_unwind, jump_table and bug_table
  which are created by inline assembly.

  Due to not being correctly aligned at link & load time they can
  trigger unnecessarily the kernel unaligned exception handler at
  runtime. While at it, I switched the bug table to use relative
  addresses which reduces the size of the table by half on 64-bit.

  We still had the ENOSYM and EREMOTERELEASE errno symbols as left-overs
  from HP-UX, which now trigger build-issues with glibc. We can simply
  remove them.

  Most of the patches are tagged for stable kernel series.

  Summary:

     build issues

the ancestor of those panel devices.  device_link_add() would fail by
returning a NULL pointer for those panel devices because of the existing
dependency.  So, check the dependency by calling device_is_dependent()
before adding or deleting device link between panel device and DRM device
so that the link is managed only for independent panel devices.

Pull s390 updates from Alexander Gordeev:

 - Remove unnecessary assignment of the performance event last_tag.

 - Create missing /sys/firmware/ipl/* attributes when kernel is booted
   in dump mode using List-directed ECKD IPL.

 - Remove odd comment.

 - Fix s390-specific part of scripts/checkstack.pl script that only
   matches three-digit numbers starting with 3 or any higher number and
   skips any stack sizes smaller than 304 bytes.

Pull ACPI fixes from Rafael Wysocki:
 "These add an ACPI IRQ override quirk for ASUS ExpertBook B1402CVA and
  fix an ACPI processor idle issue leading to triple-faults in Xen HVM
  guests and an ACPI backlight driver issue that causes GPUs to
  misbehave while their children power is being fixed up.

  Specifics:

   - Avoid powering up GPUs while attempting to fix up power for their
     children (Hans de Goede)

   - Use raw_safe_halt() instead of safe_halt() in acpi_idle_play_dead()
     so as to avoid triple-falts during CPU online in Xen HVM guests due
     to the setting of the hardirqs_enabled flag in safe_halt() (David
     Woodhouse)

   - Add an ACPI IRQ override quirk for ASUS ExpertBook B1402CVA (Hans
     de Goede)"
