Marek Olšák c18b117049 drm/radeon: allow FP16 color clear registers on r500
Probably not a candidate for stable kernels because of conflicts
in DRM versioning.

Marek Olšák fff1ce4dc6 drm/radeon/kms: check AA resolve registers on r300
This is an important security fix because we allowed arbitrary values
to be passed to AARESOLVE_OFFSET. This also puts the right buffer address
in the register.

Marek Olšák 48c36c8f9a drm/radeon/kms: allow r500 US_FORMAT regs in the CS checker
add to the 2.8 bump for pageflip

The purpose of these regs is to work around a TX hw bug in R520.

Dave Airlie ab9e1f5966 drm/radeon: add basic zmask/hiz support (v4)
This interface allows userspace to request hyperz support, it probably
needs more locking, and really reporting that you can have hyperz is racy
since someone else might get it before you do.

v2: modify so we pass 0 valued packets to let DDX/r300c keep working.
also fixed incorrect 0x4f1c reference.

v3: fixup zb_bw_cntl so older drivers keep working

v4: add locking, fixup SC_HYPERZ_EN - patch stream to disable hiz

Dave Airlie 50f153036c drm/radeon/kms: generate the safe register tables.
Previously we just made these offline and included them,
but no reason we can't generate them at build time.

TODO: add rs690 + r100/r200 when done.
should we do rs480/rs690 no tcl version?
