Tungsten Graphics, this is NOT the new memory manager, this is a replacement

When writeback isn't used, actually disable it in the hardware.

Not doing this might waste bus bandwidth or even cause memory corruption or
system crashes on systems that check bus transfers. No such incident has been
reported though.

This patch removes the pci_domain from the DRM device structure, and
gets it via a macro that either asks the platform or does the alpha special
case. jgarzik asked for this to just use the platform magic, but I've no
alpha experience and I'd rather not just break it and wait for someone to
give out.

locking init cleanups:

 - convert " = SPIN_LOCK_UNLOCKED" to spin_lock_init() or DEFINE_SPINLOCK()
 - convert rwlocks in a similar manner

this patch was generated automatically.

Motivation:

 - cleanliness
 - lockdep needs control of lock initialization, which the open-coded
   variants do not give
 - it's also useful for -rt and for lock debugging in general

Add support for r200 vertex programs (R200_EMIT_VAP_PVS_CNTL, and new
packet type for making it possible to address whole tcl vector space

From: Roland Scheidegger (DRM CVS)

Do a tcl state flush before accessing tcl vector space. This fixes some
more problems with flickering (bug #6637). drm may not be appropriate
place for this, since doing that flush there might both be overkill and
insufficient in some cases. However, it's hard to figure out when that
flush is needed, so this has to suffice. There does not seem to be a
performance penalty associated with it.
