the evergreen CS parser has allowed this for a while, just port
the code to the r600 one.
This is required before geom shaders can be made work.
v2: agd5f: minor cleanup and add additional 7xx reg.

Checking of the second colorbuffer was skipped on r700, because
CB_TARGET_MASK was 0xf. With r600, CB_TARGET_MASK is changed to 0xff,
so we must set the number of samples of the second colorbuffer to 1 in order
to pass the CS checker.
The DRM version is bumped, because RESOLVE_BOX is always rejected without this
fix on r600.

For 6xx+. Required for mesa to use htile support for HiZ/HiS.
Userspace will check radeon version 2.14 with is bumped either
by tiling patch or stream out patch. This patch only add support
for htile relocation which should be enough for any userspace
to implement the hyperz (using htile buffer) feature.
v2: Jerome: Fix size checking for htile buffer.
v3: Jerome: Adapt on top of r600/evergreen cs checker changes,
also check htile surface in case only stencil is
present.

evergreen and northern island gpu needs more informations for 2D tiling
than previous r6xx/r7xx. Add field to tiling ioctl to allow userspace
to provide those.
The v8 cs checking change to track color view on r6xx/r7xx doesn't
affect old userspace as old userspace always emited 0 for this register.
v2 fix r6xx/r7xx 2D tiling computation
v3 fix r6xx/r7xx height align for untiled surface & add support for
tile split on evergreen and newer
v4 improve tiling debugging output
v5 fix tile split code for evergreen and newer
v6 set proper tile split for crtc register
v7 fix tile split limit value
v8 add COLOR_VIEW checking to r6xx/r7xx checker, add evergreen cs
checking, update safe reg for r600, evergreen and cayman.
Evergreen checking need some work around for stencil alignment
issues
v9 fix tile split value range, fix compressed texture handling and
mipmap calculation, allow evergreen check to be silencious in
front of current broken userspace (depth/stencil alignment issue)
v10 fix eg 3d texture and compressed texture, fix r600 depth array,
fix r600 color view computation, add support for evergreen stencil
split
v11 more verbose debugging in some case

v2: agd5f: add strmout CS checking, copy_dw register checking
v3: agd5f: don't use cs_check_reg() for copy_dw checking as it
will incorrectly patch the command stream for certain regs.
v4: agd5f: add warning if safe reg check fails for copy_dw
v5: agd5f: add stricter checking for 6xx/7xx
v6: agd5f: add range checking for copy_dw on eg+,
add sx_surface_sync to safe reg list for 7xx.
v7: agd5f: add stricter checking for eg+

- Drop some more safe regs taht userspace shouldn't hit
- Constant base regs need relocs. This allows us to use
constant buffers rather than the constant register file.
Also we don't want userspace to be able to set arbitrary
mc base values for the const caches.
- Track SQ_CONFIG so we know whether userspace is using
the cfile or constant buffers.

This patch add cs checker to r600/r700 hw. Command stream checking
will rewrite some of the cs value in order to restrict GPU access
to BO size. This doesn't break old userspace but just enforce safe
value. It should break any things that was using the r600/r700 cs
ioctl to do forbidden things (malicious software), though we are
not aware of such things.
Here is the list of thing we check :
- enforcing resource size
- enforcing color buffer slice tile max, will restrict cb access
- enforcing db buffer slice tile max, will restrict db access
We don't check for shader bigger than the BO in which they are
supposed to be, such use would lead to GPU lockup and is harmless
from security POV, as far as we can tell (note that even checking
for this wouldn't prevent someone to write bogus shader that lead
to lockup).
This patch has received as much testing as humanly possible with
old userspace to check that it didn't break such configuration.
However not all the applications out there were tested, thus it
might broke some odd, rare applications.
