In the Linux kernel, the following vulnerability has been resolved:

drm/v3d: Disable preemption while updating GPU stats

We forgot to disable preemption around the write_seqcount_begin/end() pair
while updating GPU stats:

  [ ] WARNING: CPU: 2 PID: 12 at include/linux/seqlock.h:221 __seqprop_assert.isra.0+0x128/0x150 [v3d]

Fix it.
