Correct to what was intended.

accessed by the gpu or needing a flush). Since this implies that the object is
wanted, emit the flush then to save time.
Makes things a lot smoother than before in some GL applications, since
before we were claiming that object needing a flush were unbusy so the
next map stalled the gpu waiting on a flush.

conflicts.

If we just read access to some data that has been accessed by the gpu,
only sleep until the end of the gpus last write (which we track). So
instead of stalling the gpu until the last time accessed, both can read
at the same time (which is allowed and coherent as long as the right
invalidation happens).
Since we check offsets from userland before we exec a batchbuffer, this
helps 965 (with lots of read only relocations in the render path) quite
a lot.

Before, as well as being kinda nasty there was a very definite race, if
the last reference to an object was removed by uvm (a map going away),
then the free path happened unlocked, this could cause all kinds of
havoc.
In order to deal with this, move to fine-grained locking. Since uvm
object locks are spinlocks, and we need to sleep in operations that will
wait on the gpu, provide a DRM_BUSY flag that is set on a locked object
that then allows us to unlock and sleep (this is similar to several
things done in uvm on pages and some object types).
The rwlock stays around to ensure that execbuffer can have acces to the
whole gtt, so ioctls that bind to the gtt need a read lock, and
execuffer gets a write lock. otherwise most ioctls just need to busy the
object that they operate on. Lists also have their own locks.
Some cleanup could be done to make this a little prettier, but it is
much more correct than previously.
Tested very very vigorously on 855 (x40) and 965 (x61s), this found numerous
bugs. Also, the I can no longer crash the kernel at will.
A bunch of asserts hidden under DRMLOCKDEBUG have been left in the code for
debugging purposes.

these maps tend to be fairly long lived so it buys us nothing other than
code complexity.

|
Since this means the necessary gtt alignment may change. Nothing did
this already, so all it does it allows the code to be simpler.

Before this change whitespace wasn't escaped during completion which
caused the ftp command to see multiple arguments where a single path
was expected. Based on similar commit made to NetBSD's ftp in 1999.

4000 and 4300 will need more work, because they don't have as many distinct
software interrupt sources as required by this implementation, so a
different IPI scheme will be necessary.
Tested on dual-processor 4625 (AV530 family) and single processor 4300
(AV400 family).
