Descriptions

In the Linux kernel, the following vulnerability has been resolved: drm/i915: Fix potential bit_17 double-free A userspace with multiple threads racing I915_GEM_SET_TILING to set the
tiling to I915_TILING_NONE could trigger a double free of the bit_17
bitmask. (Or conversely leak memory on the transition to tiled.) Move
allocation/free'ing of the bitmask within the section protected by the
obj lock. [tursulin: Correct fixes tag and added cc stable.]
(cherry picked from commit 10e0cbaaf1104f449d695c80bcacf930dcd3c42e)
