We already have the helper, we can convert the rest of the kernel
mechanically using:
git grep -l 'atomic_inc_not_zero.*mm_users' | xargs sed -i 's/atomic_inc_not_zero(&\(.*\)->mm_users)/mmget_not_zero\(\1\)/'
This is needed for a later patch that hooks into the helper, but might be
a worthwhile cleanup on its own.

Apart from adding the helper function itself, the rest of the kernel is
converted mechanically using:
git grep -l 'atomic_inc.*mm_count' | xargs sed -i 's/atomic_inc(&\(.*\)->mm_count);/mmgrab\(\1\);/'
git grep -l 'atomic_inc.*mm_count' | xargs sed -i 's/atomic_inc(&\(.*\)\.mm_count);/mmgrab\(\&\1\);/'
This is needed for a later patch that hooks into the helper, but might be
a worthwhile cleanup on its own.

Now that %z is standartised in C99 there is no reason to support %Z.
Unlike %L it doesn't even make format strings smaller.
Use BUILD_BUG_ON in a couple ATM drivers.
In case anyone didn't notice lib/vsprintf.o is about half of SLUB which is
in my opinion is quite an achievement. Hopefully this patch inspires
someone else to trim vsprintf.c more.

I did not touch the "N_BYTE_ALIGMENT" macro in

I fixed "_aligment_handler" in arch/openrisc/kernel/entry.S because

Until recently vlv_steal_power_sequencer() wasn't being called for
normal DP ports, and hence it could assert that it should only be
called for pipe A and B (since pipe C doesn't support eDP). However
that changed when we started to consider normal DP ports as well when
choosing a PPS. So we will now get spurious warnings when
vlv_steal_power_sequencer() does get called for pipe C. Avoid this by
moving the WARN down into vlv_detach_power_sequencer() where this
assertion should still hold.

Following a reset, the context and page directory registers are lost.
However, the queue of requests that we resubmit after the reset may
depend upon them - the registers are restored from a context image, but
that restore may be inhibited and may simply be absent from the request
if it was in the middle of a sequence using the same context. If we
prime the CCID/PD registers with the first request in the queue (even
for the hung request), we prevent invalid memory access for the
following requests (and continually hung engines).

For LSPCON resume time initialization we need to sample the
corresponding pin's HPD level, but this is only available when HPD
detection is enabled. Currently we enable detection only when enabling
HPD interrupts which is too late, so bring the enabling of detection
earlier.
This is needed by the next patch.

In commit 957870f93412 ("drm/i915: Split out i915_gem_object_set_tiling()"),
I swapped an alignment check for IS_ALIGNED and in the process removed
the less-than check. That check turns out to be important as it was the
only rejection for stride == 0. Tvrtko did spot it, but I was
overconfident in the IS_ALIGNED() conversion.

100% reproducible issue found on SKL SkullCanyon NUC with two external
DP daisy-chained monitors in DP/MST mode. When turning off or changing
the input of the second monitor the machine stops with a kernel
oops. This issue happened with 4.8.8 as well as drm/drm-intel-nightly.
This issue is traced to an inconsistent control flow in
drm_dp_update_payload_part1(): the 'port' pointer is set to NULL at the
same time as 'req_payload.num_slots' is set to zero, but the pointer is
dereferenced even when req_payload.num_slot is zero.
The problematic dereference was introduced in commit dfda0df34
("drm/mst: rework payload table allocation to conform better") and may
impact all versions since v3.18
The fix suggested by Chris Wilson removes the kernel oops and was found to
work well after 10mn of monkey-testing with the second monitor power and
input buttons

Like ttm_bo_validate(), ttm_bo_init() might need to move BO and
the number of bytes moved by TTM should be reported. This can help
the throttle buffer migration mechanism to make a better decision.

When ttm_bo_init() fails, the reservation mutex should be unlocked.
In debug build, the kernel reported "possible recursive locking
detected" in this codepath. For debugging purposes, I also added
a "WARN_ON(ww_mutex_is_locked())" when ttm_bo_init() fails and the
mutex was locked as expected.
This should fix (random) GPU hangs. The easy way to reproduce the
issue is to change the "Super Sampling" option from 1.0 to 2.0 in
Hitman. It will create a huge buffer, evict a bunch of buffers
(around ~5k) and deadlock.
This regression has been introduced pretty recently.

The fault wrappers drm_vm_fault(), drm_vm_shm_fault(), drm_vm_dma_fault()
and drm_vm_sg_fault() used to provide extra logic beyond what was in the
"drm_do_*" versions of these functions, but as of this commit:
commit ca0b07d9a969 ("drm: convert drm from nopage to fault.")
They are just unnecessary wrappers that do nothing. Remove them, and
rename the the drm_do_* fault handlers to remove the "do_" since they no
longer have corresponding wrappers.
