The guest recovery sequence is buggy in Fatal Error when both

FLR guest recovery sequence is out of order when PF/VF communication
breaks due to a GPU fatal error
As a temporary work around, perform a KFD style reset (Initiate reset

When the link BW is smaller than the request BW,

[Why]
Missing check for when there is new pipe configuration but both cur_pipe
and new_pipe are both populated causing update_state of DSC for that
instance not being updated correctly.
This causes some display mode changes to cause underflow since DSCCLK
is still gated when the display requires DSC.
[How]
Added another condition in the new pipe addition branch that checks if
there is a new pipe configuration and if it is not the same as cur_pipe.
cur_pipe does not necessarily have to be NULL to go in this branch.

V3D_PERFCNT_NUM represents the maximum number of performance counters
for V3D 4.2, but not for V3D 7.1. This means that, if we use
V3D_PERFCNT_NUM, we might go out-of-bounds on V3D 7.1.
Therefore, use the number of performance counters on V3D 7.1 as the
maximum number of counters. This will allow us to create arrays on the
stack with reasonable size. Note that userspace must use the value
provided by DRM_V3D_PARAM_MAX_PERF_COUNTERS.

Userspace usually needs some information about the performance counters
available. Although we could replicate this information in the kernel
and user-space, let's use the kernel as the "single source of truth" to
avoid issues in the future (e.g. list of performance counters is updated
in user-space, but not in the kernel, generating invalid requests).
Therefore, create a new IOCTL to expose the performance counters
information, that is name, category, and description.

Currently, even though V3D 7.1 has 93 performance counters, it is not
possible to create counters bigger than 87, as
`v3d_perfmon_create_ioctl()` understands that counters bigger than 87

Therefore, create a device variable to expose the maximum
number of counters for a given V3D version and make
`v3d_perfmon_create_ioctl()` check this variable.

The connector is created by either this ADV7511 bridge driver or
any DRM device driver/previous bridge driver, so this ADV7511
bridge driver should not let the next bridge driver create connector.
If the next bridge is a HDMI connector, the next bridge driver
would fail to attach bridge from display_connector_attach() without
the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag.
Add that flag to drm_bridge_attach() function call in
adv7511_bridge_attach() to fix the issue.
This fixes the issue where the HDMI connector bridge fails to attach

This is a simple first-cut implementation for now. The series is
"support multi-size THP numa balancing".
- Cleanups to vma handling helper functions from Matthew Wilcox in
the series "Unify vma_address and vma_pgoff_address".
- Some selftests maintenance work from Dev Jain in the series
"selftests/mm: mremap_test: Optimizations and style fixes".
- Improvements to the swapping of multi-size THPs from Ryan Roberts
in the series "Swap-out mTHP without splitting".
- Kefeng Wang has significantly optimized the handling of arm64's
permission page faults in the series
"arch/mm/fault: accelerate pagefault when badaccess"
"mm: remove arch's private VM_FAULT_BADMAP/BADACCESS"
- GUP cleanups from David Hildenbrand in "mm/gup: consistently call
it GUP-fast".
- hugetlb fault code cleanups from Vishal Moola in "Hugetlb fault
path to use struct vm_fault".
- selftests build fixes from John Hubbard in the series "Fix
selftests/mm build without requiring "make headers"".
- Memory tiering fixes/improvements from Ho-Ren (Jack) Chuang in the
series "Improved Memory Tier Creation for CPUless NUMA Nodes".
Fixes the initialization code so that migration between different
memory types works as intended.
- David Hildenbrand has improved follow_pte() and fixed an errant
driver in the series "mm: follow_pte() improvements and acrn
follow_pte() fixes".
- David also did some cleanup work on large folio mapcounts in his
series "mm: mapcount for large folios + page_mapcount() cleanups".
- Folio conversions in KSM in Alex Shi's series "transfer page to
folio in KSM".
- Barry Song has added some sysfs stats for monitoring multi-size
THP's in the series "mm: add per-order mTHP alloc and swpout
counters".
- Some zswap cleanups from Yosry Ahmed in the series "zswap
same-filled and limit checking cleanups".
- Matthew Wilcox has been looking at buffer_head code and found the
documentation to be lacking. The series is "Improve buffer head
documentation".
- Multi-size THPs get more work, this time from Lance Yang. His
series "mm/madvise: enhance lazyfreeing with mTHP in madvise_free"
optimizes the freeing of these things.
- Kemeng Shi has added more userspace-visible writeback
instrumentation in the series "Improve visibility of writeback".
- Kemeng Shi then sent some maintenance work on top in the series
"Fix and cleanups to page-writeback".
- Matthew Wilcox reduces mmap_lock traffic in the anon vma code in
the series "Improve anon_vma scalability for anon VMAs". Intel's
test bot reported an improbable 3x improvement in one test.
- SeongJae Park adds some DAMON feature work in the series
"mm/damon: add a DAMOS filter type for page granularity access recheck"
"selftests/damon: add DAMOS quota goal test"
- Also some maintenance work in the series
"mm/damon/paddr: simplify page level access re-check for pageout"
"mm/damon: misc fixes and improvements"
- David Hildenbrand has disabled some known-to-fail selftests ni the
series "selftests: mm: cow: flag vmsplice() hugetlb tests as
XFAIL".
