Thomas Hellstrom 496eb6fd2c drm/vmwgfx: Replace the hw mutex with a hw spinlock ... Fixes a case where we call vmw_fifo_idle() from within a wait function with task state !TASK_RUNNING, which is illegal. In addition, make the locking fine-grained, so that it is performed once for every read- and write operation. This is of course more costly, but we don't perform much register access in the timing critical paths anyway. Instead we have the extra benefit of being sure that we don't forget the hw lock around register accesses. I think currently the kms code was quite buggy w r t this.
