2015-11-26drm/ttm: Fixed a read/write lock imbalanceThomas Hellstrom
In ttm_write_lock(), the uninterruptible path should call __ttm_write_lock() not __ttm_read_lock(). This fixes a vmwgfx hang on F23 start up. syeh: Extracted this from one of Thomas' internal patches.

2009-12-07drm/ttm: Add ttm lock functionality.Thomas Hellstrom
This is intended to be used by ttm-aware drivers to 1) Block clients to inactive masters when they try to validate buffers for GPU use. 2) Optionally block clients to the current master when there is thrashing due to GPU memory shortage. Used by the vmwgfx driver. Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
