The devm_request_threaded_irq() and devm_request_irq() now automatically
log detailed error messages on failure. This eliminates the need for
driver-specific dev_err() and dev_err_probe() calls that previously
printed generic messages.

Fix a coccinelle warning about do_div() truncating a 64-bit divisor:
sound/soc/fsl/fsl_easrc.c:2061:2-8: WARNING: do_div() does a 64-by-32 division, please consider using div64_u64 instead.
In fsl_easrc_m2m_calc_out_len(), val1 is computed as:
val1 = (u64)in_rate << frac_bits; // frac_bits up to 39
do_div(val1, out_rate);
val1 += (s64)ctx_priv->ratio_mod << (frac_bits - 31);
val1 = val1 >> 12;
In the worst case (in_rate=384000, out_rate=8000, frac_bits=39):
val1 = 384000 << 39 / 8000 = 26,388,279,068,672
val1 >> 12 = 6,440,497,829 (33 bits, exceeds 32-bit range)
val1 is then used as the divisor in do_div(val2, val1), where
do_div() silently truncates it to 32 bits, producing incorrect
results. Use div64_u64() to perform a proper 64-by-64 division.

On Shikra, the DDR System Firmware (DSF) configures ECC interrupt
routing before the kernel driver probes — it enables Tag/Data RAM
interrupts and programs error thresholds in the LLCC interrupt-enable
registers.
Set irq_configured in shikra_cfg so that qcom_llcc_edac_probe() skips
calling qcom_llcc_core_setup(), which would otherwise overwrite the
firmware-managed register state with redundant writes.

With commit 98149f542530 ("selftests/cgroup: Add test for cpuset affinity
on controller disable"), sashiko [1] reported 3 different issues with
the new test_cpuset_affinity_on_controller_disable() test.
1) `cpu_set_equal` iterates over mask bytes instead of bits, ignoring
CPUs >= 8.
2) Thread synchronization logic allows the main thread to read
uninitialized stack memory, causing test flakiness.
3) Test fails instead of skipping gracefully on uniprocessor systems
or when CPU 1 is unavailable.
Fix the reported issues by:
1) Iterates over the bit size of the mask.
2) Test the new ready flag for each thread to end the wait
on the conditional variable and eliminate the now unneeded
AFFINITY_THREAD_A_READY and AFFINITY_THREADS_READY test phases.
3) Return KSFT_SKIP on "cpuset.cpus" setting failure.

Now that proper fixes have been found, let's revert this workaround.
This reverts commit a1fc7bf6677eb547167cb72b3bcafdc34b976692.

[Why]
After unifying DCN interrupt sources under VUPDATE_NO_LOCK, we have two
remaining issues to clean up:
1. On DCN, flip completion is now delivered from VUPDATE_NO_LOCK
(dm_crtc_high_irq_handler) instead of GRPH_PFLIP. But VUPDATE_NO_LOCK
fires every frame, regardless of whether a flip has latched.
2. There is a window during commit where a flip is armed (pflip_status =
SUBMITTED) but not yet programmed into HW. If the VUPDATE_NO_LOCK
fires in that window, its handler would deliver a flip event to
userspace before HW has latched to it. If userspace then renders to
what it believes is now the back buffer (but HW is still latched to
it!), it will cause display corruption. This issue seemed to have
been introduced by:
commit 1159898a88db ("drm/amd/display: Handle commit plane with no FB.")
Enabling replay or psr extended the duration of this window, and
hence made corruption more likely to be observed.
[How]
* Move acrtc->event/pflip_status arming to after
update_planes_and_stream_adapter() has programmed the flip into HW.
This closes the window where pflip_status is SUBMITTED but the flip is
not yet programmed.
* Add dc_get_flip_pending_on_otg(), which reads the HUBP flip-pending
status straight from HW for the pipe(s) bound to an OTG instance. It
is keyed only by otg_inst and does not take or mutate a
dc_plane_state, so it is safe to call from the OTG interrupt handler
without racing a concurrent commit that may be modifying plane state.
* Optimistically query for flip-pending after programming, in the event
that HW latched to the new fb between programming start and arming
event. If it latched, send the vblank event immediately, rather than
wait for the next vblank IRQ.
* In the VUPDATE_NO_LOCK handler, only deliver flip completion once
dc_get_flip_pending_on_otg() reports the flip is no longer pending.
Otherwise leave the flip armed and retry on the next vupdate.
* For DCE, maintain the existing behavior of arming flips before
programming, and relying on GRPH_FLIP to fire at HW latch.
v2:
* Drop flip_programmed completion object, instead move
event/pflip_status arming after programming.
* For DCN, optimistically query for flip pending immediately after
programming, and if it latched, send event right away.
v3:
* Fix event timestamps on optimistic flip latch detection, where it's
possible for it to run *before* the vupdate IRQ updates the timestamp.
* Add more docstrings for DCN vblank handling.
* Clean up if conditions in dm_arm_vblank_event().
* Code style cleanup on braces surrounding multi-line statements.

[Why]
On DCN, vblank events were delivered from VSTARTUP/VUPDATE
(dm_crtc_high_irq/dm_vupdate_high_irq) and pageflip completion from
GRPH_PFLIP (dm_pflip_high_irq). These signals can be masked by hardware
by a few things:
* DPG - DCN can Dynamically Power Gate parts of the display pipe when a
self-refresh capable eDP is connected. DPG is engaged when there's
enough static frames (detected through drm_vblank_off). Once gated,
even though the OTG (output timing generator) is still enabled,
VSTARTUP and GRPH_FLIP are masked.
* GSL - Driver can use the Global Sync Lock to block HW from latching
onto double-buffered registers during programming, to prevent HW from
latching onto a partially programmed state. This will mask VSTARTUP,
GRPH_FLIP, and VUPDATE. See dcn20_pipe_control_lock().
* MALL - A DCN accessible cache introduced in DCN32+ DGPUs that can
store fb data to allow for longer DRAM sleep. When scanning out from
MALL, VSTARTUP is masked.
When masked, events are never delivered, which can show up as flip_done
timeouts in the wild.
However, there is an interrupt source on DCN that is never masked:
VUPDATE_NO_LOCK. It's simply an unmasked variant of VUPDATE, which fires
while the OTG is active, at the exact point hardware latches
double-buffered registers. It is therefore the natural single signal for
delivering both vblank and flip-completion events on DCN, and the
correct point to timestamp both VRR and non-VRR vblanks.
DCE's interrupt sources are different, it does not have an unmaskable
VUPDATE_NO_LOCK. The only unmaskable DCE interrupt is VLINE0, but it can
only be programmed as a vline offset from vsync_start, making it
unsuitable for VRR. Thus, we keep DCE untouched and use the existing mix
of interrupt sources.
[How]
For DCN1 and newer only:
* Factor the body of dm_crtc_high_irq() into dm_crtc_high_irq_handler()
and drive it from dm_vupdate_high_irq() (VUPDATE_NO_LOCK). DCE keeps
using dm_crtc_high_irq() (VSTARTUP) and dm_pflip_high_irq()
(GRPH_PFLIP) unchanged.
* Stop registering VSTARTUP (crtc_irq) and GRPH_PFLIP (pageflip_irq) on
DCN, and stop enabling them in amdgpu_dm_crtc_set_vblank() /
manage_dm_interrupts(). Enable VUPDATE whenever vblank is enabled on
DCN (previously only in VRR mode). The secure-display vline0 interrupt
is left untouched.
* VUPDATE_NO_LOCK does not early-fire on an immediate (tearing / async)
flip, since HW latches the new address right away. Deliver the flip
completion event immediately after programming such flips in
amdgpu_dm_commit_planes(), and clear pflip_status so the next vupdate
handler does not double-send.
v2: Do not gate VUPDATE_NO_LOCK on DCN in dm_handle_vrr_transition()
Also toggle VUPDATE_NO_LOCK on DCN in dm_gpureset_toggle_interrupts()
Re-cook vblank event count and timestamp for immediate flips
