It has been reported that this greatly improves (and possibly fixes
completely) the stability of NVA3+ chipsets.  In traces of my NVA8,
NVIDIA now appear to be doing this too.

The most recent traces of 0x50 and 0xac I could find don't show NVIDIA
checking PGRAPH status on these flushes, so for now, we won't either.

Avoid touching the flip setup regs while
acceleration is running.  Set them at modeset
rather than during pageflip.  Touching these
regs while acceleration is active caused hangs
on pre-avivo chips.  These chips do not seem
to be affected, but better safe than sorry,
plus it avoids repeatedly reprogramming the
regs every flip.

Once a NAK has been asserted by the slave, we need to reset the GMBUS
controller in order to continue. This is done by asserting the Software
Clear Interrupt bit and then clearing it again to restore operations.

If we don't clear the NAK, then all future GMBUS xfers will fail,
including DDC probes and EDID retrieval.

v2: Add some comments as suggested by Keith Packard.

During modesetting, we need to wait for the hardware to report
readiness by polling the registers. Normally, we call msleep() between
reads, because some state changes may take a whole vblank or more
to complete. However during a panic, we are in an atomic context and
cannot sleep. Instead, busy spin polling the termination condition.

Fix the incorrect use of igrab() inside the i_lock in NFS and Ceph‥

If we are already holding the i_lock, we have a reference to the
inode so we can safely use ihold() to gain an extra reference. This
avoids hangs due to lock recursion on the i_lock now that the
inode_lock is gone and igrab() uses the i_lock itself.
