If a regmap has "fast_io" set then its lock function uses a spinlock.
That doesn't work so well with the functions:
* regmap_cache_only_write_file()
* regmap_cache_bypass_write_file()

Both of the above functions have the pattern:
1. Lock the regmap.
2. Call:
   debugfs_write_file_bool()
     copy_from_user()
       __might_fault()
         __might_sleep()

Let's reorder things a bit so that we do all of our sleepable
functions before we grab the lock.

Currently, when using _of_add_opp_table_v2 parsed_static_opps is
increased and this value is used in _opp_remove_all_static() to
check if there are static opp entries that need to be freed.
Unfortunately this does not happen when using _of_add_opp_table_v1(),
which leads to warnings.

This patch increases parsed_static_opps in _of_add_opp_table_v1() in a
similar way as in _of_add_opp_table_v2().

The afs filesystem driver allows unstarted operations to be cancelled by
signal, but most of these can easily be restarted (mkdir for example).  The
primary culprits for reproducing this are those applications that use
SIGALRM to display a progress counter.

File lock-extension operation is marked uninterruptible as we have a
limited time in which to do it, and the release op is marked
uninterruptible also as if we fail to unlock a file, we'll have to wait 20
mins before anyone can lock it again.

The store operation logs a warning if it gets interruption, e.g.:

	kAFS: Unexpected error from FS.StoreData -4

because it's run from the background - but it can also be run from
fdatasync()-type things.  However, store options aren't marked
interruptible at the moment.

Fix this in the following ways:

 (1) Mark store operations as uninterruptible.  It might make sense to
     relax this for certain situations, but I'm not sure how to make sure
     that background store ops aren't affected by signals to foreground
     processes that happen to trigger them.

 (2) In afs_get_io_locks(), where we're getting the serialisation lock for
     talking to the fileserver, return ERESTARTSYS rather than EINTR
     because a lot of the operations (e.g. mkdir) are restartable if we
     haven't yet started sending the op to the server.

This reverts commit eb9aecd9

The above patch is supposed to fix a register index error on mt2701. It
is not clear if the problem solved is a hang or just an invalid value
returned, my guess is the second. The patch introduces, though, a new
hang on MT8173 device making them unusable. So, seems reasonable, revert
the patch because introduces a worst issue.

The reason I send a revert instead of trying to fix the issue for MT8173
is because the information needed to fix the issue is in the datasheet
and is not public. So I am not really able to fix it.

Fixes the following bug when CONFIG_MTK_THERMAL is set on MT8173
devices.

"u64 *wptr" points to the the wptr value in write back buffer and
"*wptr = (*wptr) >> 2;" results in the value being overwritten each time
when ->get_wptr() is called.

umr uses /sys/kernel/debug/dri/0/amdgpu_ring_sdma0 to get rptr/wptr and
decode ring content and it is affected by this issue.

fix and simplify the logic similar as sdma_v4_0_ring_get_wptr().

v2: fix for sdma5.2 as well
v3: drop sdma 5.2 changes for 5.8 and stable

I consulted Cai Land(Chuntian.Cai@amd.com), he told me corresponding smc
message name to fSMC_MSG_SetWorkloadMask() is
"PPSMC_MSG_ActiveProcessNotify" in firmware code of Renoir.

Strange though it may seem, but it's a fact.

[Why]
amdgpu_dm->backlight_caps is for single eDP only. the caps are upddated
for very connector. Real eDP caps will be overwritten by other external
display. For OLED panel, caps->aux_support is set to 1 for OLED pnael.
after external connected, caps+.aux_support is set to 0. This causes
OLED backlight adjustment not work.

[How]
within update_conector_ext_caps, backlight caps will be updated only for
eDP connector.

Prevents a warning in the MST create connector case.

v2: create global fake encoders rather per connector fake encoders
to avoid running out of encoder indices.

v3: use the actual number of crtcs on the asic rather than the max
to conserve encoders.

v4: v3 plus missing hunk I forgot to git add.

Currently we're failing to recalculate the gen9 FBC w/a stride
unless something more drastic than just the modifier itself has
changed. This often leaves us with FBC enabled with the linear
fbdev framebuffer without the w/a stride enabled. That will cause
an immediate underrun and FBC will get promptly disabled.

Fix the problem by checking if the w/a stride is about to change,
and go through the full dance if so. This part of the FBC code
is still pretty much a disaster and will need lots more work.
But this should at least fix the immediate issue.

v2: Deactivate FBC when the modifier changes since that will
    likely require resetting the w/a CFB stride
