This reverts commit a6f97617.

Remove this commit as it is no longer necessary. The relevant bugs
were fixed properly in:
drm/radeon/kms: hopefully fix pll issues for real (v3)
5b40ddf8
drm/radeon/kms: add missing frac fb div flag for dce4+
9f4283f4

This commit also broke certain ~5 Mhz modes on old arcade monitors,
so reverting this commit fixes:

The fixed ref/post dividers are set by the AdjustPll table
rather than the ss info table on dce4+.  Make sure we enable
the fractional feedback dividers when using a fixed post

The problematic boards have a recommended reference divider
to be used when spread spectrum is enabled on the laptop panel.
Enable the use of the recommended reference divider along with
the new pll algo.

v2: testing options

v3: When using the fixed reference divider with LVDS, prefer
min m to max p and use fractional feedback dividers.

My evergreen has been in a remote PC for week and reset has never once
saved me from certain doom, I finally relocated to the box with a

delayed delete thread tries to remove something from the GTT.

This stops the delayed delete thread from executing across the GPU
reset handler, and woot I can GPU reset now.

The colorbuffer, zbuffer, and texture states are checked only once when
they get changed. This improves performance in the apps which emit
lots of draw packets and few state changes.

This drops performance in glxgears by a 1% or so, but glxgears is not
a benchmark we care about.
The time spent in the kernel when running Torcs dropped from 33% to 23%
and the frame rate is higher, which is a good thing.

r600 might need something like this as well.

drivers/gpu/drm/radeon/mkregtable.c:parser_auth() almost always remembers
to fclose(file) before returning, but it misses two spots.

This is not really important since the process will exit shortly after and
thus close the file for us, but being explicit prevents static analysis
tools from complaining about leaked memory and missing fclose() calls and
it also seems to be the prefered style of the existing code to explicitly
close the file.

So, here's a patch to add the two missing fclose() calls.

- set scaler table clears the interleave bit, need to
reset it in encoder quirks, this was already done for
pre-dce4.
- remove the interleave settings from set_base() functions
this is now handled in the encoder quirks functions, and
isn't technically part of the display base setup.
- rename evergreen_do_set_base() to dce4_do_set_base() since
it's used on both evergreen and NI asics.

The -rt patches change the console_semaphore to console_mutex.  As a
result, a quite large chunk of the patches changes all
acquire/release_console_sem() to acquire/release_console_mutex()

This commit makes things use more neutral function names which dont make
implications about the underlying lock.

The only real change is the return value of console_trylock which is
inverted from try_acquire_console_sem()

This patch also paves the way to switching console_sem from a semaphore to
a mutex.
