drm/nouveau: fix required mode bandwidth calculation for DP
This should fix eDP on certain laptops with 18-bit panels, we were rejecting
the panel's native mode due to thinking there was insufficient bandwidth
for it.

This isn't correct everywhere yet, but since we don't use the data yet
it's perfectly safe to push in, and the information we gain from logs

v2 (Ben Skeggs <bskeggs@redhat.com>):
- fixed up formatting
- free parsed timing info on takedown
- switched timing table printout to debug loglevel

drm/nouveau: fix panels using straps-based mode detection
nouveau_bios_fp_mode() zeroes the mode struct before filling in relevant

drm/nouveau: Parse old style perf tables.
Used on nv17-nv28, they contain memory clocks and timings, only one of
the table entries can actually be used, depending on the RAMCFG
straps, and it's usually higher than the frequency programmed on boot
by the BIOS.
The memory timings listed in table version 0x1x are used to init the
0x12xx range but they aren't required for reclocking to work.

It doesn't seem to revert cleanly, but the problem lies in these
two config entries:
CONFIG_ACPI=y
CONFIG_ACPI_VIDEO=m
Adding a select for ACPI_VIDEO appears to be the best solution, and
is comparable to what is done in DRM_I915. Builds, boots, and appears to
work correctly.

drm/nouveau: handle fifo pusher errors better
The most important part of this change is that we now instruct PFIFO to
drop all pending fetches, rather than attempting to skip a single dword
and hope that things would magically sort themselves out - they usually
don't, and we end up with PFIFO being completely hung.
This commit also adds somewhat more useful logging when these exceptions
occur.

This doesn't actually happen now, but there's a test case for an earlier

On some boards the residual current DAC outputs can draw when they're

drm/nv20: Use the nv30 CRTC bandwidth calculation code.
nv2x CRTC FIFOs are as large as in nv3x (4kB it seems), and the FIFO
control registers have the same layout: we can make them share the
same implementation.
Previously we were using the nv1x code, but the calculated FIFO
watermarks are usually too low for nv2x and they cause horrible
scanout artifacts. They've gone unnoticed until now because we've been
leaving one of the bandwidth regs uninitialized (CRE 47, which
contains the most significant bits of FFLWM), so everything seemed to
work fine except in some cases after a cold boot, depending on the
memory bandwidth and pixel clocks used.

hugetlb, rmap: fix confusing page locking in hugetlb_cow()
The "if (!trylock_page)" block in the avoidcopy path of hugetlb_cow()
looks confusing and is buggy. Originally this trylock_page() was
intended to make sure that old_page is locked even when old_page !=
pagecache_page, because then only pagecache_page is locked.
This patch fixes it by moving page locking into hugetlb_fault().
Change the code so that it will use the correct size for keymap entries.
Do it in a way that makes it harder to screw it up in the future.
