From: Ira Weiny <ira.weiny at intel.com>

This series starts by converting the last easy kmap() uses to
kmap_local_page().

There is one more call to kmap() wrapped in ttm_bo_kmap_ttm().  Unfortunately,
ttm_bo_kmap_ttm() is called in a number of different ways including some which
are not thread local.  I have a patch to convert that call.  However, it is not
straight forward so it is not included in this series.

The final 2 patches fix bugs found while working on the ttm_bo_kmap_ttm()
conversion.


Ira Weiny (7):
drm/i915: Replace kmap() with kmap_local_page()
drm/amd: Replace kmap() with kmap_local_page()
drm/gma: Remove calls to kmap()
drm/radeon: Replace kmap() with kmap_local_page()
drm/msm: Alter comment to use kmap_local_page()
drm/amdgpu: Ensure kunmap is called on error
drm/radeon: Ensure kunmap is called on error
