Rearrange the allocation of the mm_struct registration to avoid
allocating underneath the i915->mm_lock, so that we avoid tainting the
lock (and in turn many other locks that may be held as i915->mm_lock is
taken, and those locks we may want on the free [shrinker] paths). In
doing so, we convert the lookup to be RCU protected by courtesy of
converting the free-worker to be an rcu_work.
v2: Remember to use hash_rcu variants to protect the list iteration from
concurrent add/del.

The default fbc1 compression interval we use is 500 frames. That
translates to over 8 seconds typically. That's rather excessive
so let's drop it to 1 second.
The hardware will not attempt recompression unless at least one
line has been modified, so a shorter compression interval should
not cause extra bandwidth use in the purely idle scenario. Of
course in the mostly idle case we are possibly going to recompress
a bit more.
Should really try to find some kind of sweet spot to minimize
the energy usage...

The current fence_y_offset calculation is broken. I think it more or
less used to do the right thing, but then I changed the plane code
to put the final x/y source offsets back into the src rectangle so
now it's just subtraacting the same value from itself. The code would
never have worked if we allowed the framebuffer to have a non-zero
offset.
Let's do this in a better way by just calculating the fence_y_offset
from the final plane surface offset. Note that we don't align the
plane surface address to fence rows so with horizontal panning there's
often a horizontal offset from the fence start to the surface address
as well. We have no way to tell the hardware about that so we just
ignore it. Based on some quick tests the invlidation still happens
correctly. I presume due to the invalidation nuking at least the full
line (or a segment of multiple lines).

As we close a handle GEM object, we update the drm_file's idr with an
error^W NULL pointer to indicate the in-progress closure, and finally
removing it. If we read the idr directly, we may then see an invalid
object pointer, and in our debugfs per_file_stats() we therefore need
to protect against the entry being invalid.

The linetime watermark is a 9 bit value, which gives us
a maximum linetime of just below 64 usec. If the linetime
exceeds that value we currently just discard the high bits
and program the rest into the register, which angers the
state checker.
To avoid that let's just clamp the value to the max. I believe
it should be perfectly fine to program a smaller linetime wm
than strictly required, just means the hardware may fetch data
sooner than strictly needed. We are further reassured by the
fact that with DRRS the spec tells us to program the smaller
of the two linetimes corresponding to the two refresh rates.

The helper uses the MIPI_DCS_SET_TEAR_SCANLINE, although it's currently
using the generic write. This does not look right.
Perhaps some platforms don't distinguish between the two writers?

A few of the new panels create a local macro wrapping around
mipi_dsi_dcs_write. At the same time, they don't really care about the
command/payload split.
mipi_dsi_dcs_write does a kmalloc/memcpy/kfree for payload > 7 bytes.
Avoid that all together by using the _buffer function.
Aside:
panel-xinpeng-xpp055c272.c calls its wrapper "generic" although it
should be "dcs". But that for another day/patch.

Currently the function heap allocates when we have any payload. Where in
many case the payload is 1 byte - ouch.
>From casual observation, vast majority of the payloads are smaller than
8 bytes - so use a stack array tx[8] to avoid the senseless kmalloc and
kfree dance.

This patch uses score to select a new drm scheduler for better
loadbalance between multiple drm schedulers instead of num_jobs.
Below are test results after running amdgpu_test for ~10 times.
Before this patch:

========= ==================================
sdma0 1463
sdma1 198
comp_1.0.1 280
After this patch:
