Commit 0108bc808107: "drm/nouveau: do not allow negative sizes for now" broke
older nvidia gpu's that lack a vm. Add an explicit check to handle this.

Commits 0a9e2b959 (drm/nvd0/disp: move HDA codec setup to core) and
a4feaf4ea (drm/nva3/disp: move hda codec handling to core) moved code
around but neglected to fill data up to 0x60 as before. This caused
/proc/asound/cardN/eld#3.0 to show eld_valid as 0. With this patch, that
file is again populated with the correct data.

Since the original merge of nouveau to upstream kernel, we were assuming
that nv90 (and later) cards have 32 lines.
Based on mmio traces of the binary driver, as well as PBUS error messages
during read/write of the e070/e074 registers, we can conclude that nv92
has only 16 lines whereas nv94 (and later) cards have 32.

Kernel panic caused by list corruption in ltcg seems to indicate a

Take mutex of pfb like nv50_ram_put() to eliminate concurrency.

The current logic is wrong since we send fw->size >> 8 to the
card. Rounding the size up by 0x100 and 0x1000 didn't seem to help,
the card still hung, so go back to what the blob does -- 0x40000.

The API allows up to 64-bits allocations, but size is handled as int
inside nouveau almost everywhere. Until this is fixed it's better to
prevent negative sizes.
The 256 kB before INT_MAX is paranoia, because of the large page
aligning below that could flip it above INT_MAX.

The moves themselves were generally async to graphics previously, with
the exception that if the "main" channel is used to synchronise a
page flip at the same time, it can end up blocked for a noticable amount
of time for large buffer moves.
Not really critical, and there's better ways of handling this, but they
are all rather invasive, so this is fine for now.
Based on a patch by Maarten Lankhorst addressing the same issue.

b580c9e2b7ba5030a795aa2fb73b796523d65a78 introduced additional problems
while trying to solve issues that became apparent while porting to the
new reservation stuff.
The major problem was that the the previously mentioned patch took the
client mutex earlier than previously, but the pinning of new_bo can
can potentially cause a buffer move, which would result in attempting to
acquire the same mutex again.
This commit attempts to fix that "fix".
Thanks to Maarten for the tips on keeping lockdep happy and cooking :)
