774c389fae drm/radeon: don't check mipmap alignment if MIP_ADDRESS is FMASK
The MIP_ADDRESS state has 2 meanings. If the texture has one sample
per pixel, it's a pointer to the mipmap chain. If the texture has
multiple samples per pixel, it's a pointer to FMASK, a metadata buffer
needed for reading compressed MSAA textures. The mipmap
alignment rules do not apply to FMASK.

3314fdf8b4 Merge branch 'drm-fb-helper' of git://people.freedesktop.org/~danvet/drm into drm-next
This is the drm fb helper cleanup, mostly motivated by strange things I've
seen in my locking rework and the i915 modeset revamp. Compared to the
original submission I've reinstated the setup flexibility you'd like to
retain, kerneldoc has been reviewed by Laurent Pinchart and Rob Clark
reviewed the code changes.

Quick overview of the changes:
- Cleaned-up library interface for drivers using the fb helper, also
  simplified the fb allocation callback since no driver supported
  reallocating the fb on-the-fly. And the fbdev/fbcon code keeps pointers
  to the old mapping around anyway, so reallocating backing storage will
  be much more work.
- No longer call the crtc helper "disable everything" function at init
  time, but allow drivers to do so. Motivated by i915's fastboot effort
  and allows us to drop a bunch of noop dummy functions just to avoid
  calling NULL function pointers from i915.ko.
- Properly clear old state when doing modeset calls, the fb helper left
  some old modes in there and unconditionally set an fb (even when
  disabling a crtc). The crtc helpers didn't care, but i915 modeset code
  can now drop a few special cases.
- Full kerneldoc for the fb helper. Yay!
- My version of the "don't sleep in panic ->unblank calls". The patch is
  already in -mm, I guess Andrew can drop it as soon as this pull lands in
  drm-next.

* 'drm-fb-helper' of git://people.freedesktop.org/~danvet/drm:
  drm/fb-helper: remove unused members of struct drm_fb_helper

76a39dbfb2 drm/fb-helper: don't disable everything in initial_config
This should be done in the drivers for two reasons:
- it gets in the way of fastboot efforts
- it links the fb helpers with the crtc helpers instead of going
  through the real interface vfuncs, forcing i915 to fake all the
  ->disable callbacks used by the crtc helper to avoid ugly Oopsen

v2: Resolve conflicts since drivers still call
drm_fb_helper_single_add_all_connectors.

When ever parsing cmd buffer supplied by userspace we need to use
radeon_get_ib_value rather than directly accessing the ib as the user
cmd might not yet be copied into the ib thus the parser might read
value that does not correspond to what user is sending and possibly
allowing user to send malicious command undected.

- CS ioctl cleanup and unification.  Unification of a lot of functionality
that was duplicated across multiple generates of hardware.
- Add support for Oland GPUs
- Deprecate UMS support.  Mesa and the ddx dropped support for UMS and
apparently very few people still use it since the UMS CS ioctl was broken
for several kernels and no one reported it.  It was fixed in 3.8/stable.
- Rework GPU reset.  Use the status registers to determine what blocks
to reset.  This better matches the recommended reset programming model.
This also allows us to properly reset blocks besides GFX and DMA.
- Switch the VM set page code to use an IB rather than the ring.  This
fixes overflow issues when doing large page table updates using a small
ring like DMA.
