As discussed in the long thread about vblank related timeouts, it turns out
GM45 has different frame count registers than previous chips.  This patch
adds support for them, which prevents us from waiting on really stale
sequence values in drm_wait_vblank (which rather than returning immediately
ends up timing out or getting interrupted).

Getting an unknown get/setparam used to be more significant back when they
didn't change much.  However, now that we're in the git world we're using
them instead of a monotonic version number to signal feature availability,
so clients ask about unknown params on older kernels more often.

Adds code to set up fence registers at execbuf time on pre-965 chips as
necessary.  Also fixes up a few bugs in the pre-965 tile register support
(get_order != ffs).  The number of fences available to the kernel defaults
to the hw limit minus 3 (for legacy X front/back/depth), but a new parameter
allows userspace to override that as needed.

Previously, the caller would continue along without knowing that the
function failed, resulting in potential mis-rendering.  Right now vm_fault
just returns SIGBUS in that case, and we may need to disable signal handling
to avoid that happening.

We'd love to just be using PAT, but even on chips with PAT it gets disabled
sometimes due to an errata.  It would probably be better to have pat_enabled

This is an initial patch to do support for objects which needs physical
contiguous main ram, cursors and overlay registers on older chipsets.

These objects are bound on cursor bin, like pinning, and we copy
the data to/from the backing store object into the real one on attach/detach.

notes:
possible over the top in attach/detach operations.
no overlay support yet.

This avoids a BUG_ON in the enter_vt path due to objects being in the GTT
when we shouldn't have ever let them be (as we're not supposed to touch the
device during that time).

This was triggered by a change in the 2D driver to use the GTT mapping of
objects after pinning them to improve software fallback performance.
