This is a follow-on set to Yakir's original PSR set here: https://lkml.org/lkml/2016/7/24/34
There are a few issues with the code that needed to be shored up.
(1) The use of mutexes instead of spinlocks caused issues calling the psr functions from vblank_enable/disable.
(2) The proliferation of workers due to (1)
(3) vblank is not enabled unless an event is requested, this breaks a lot of things, but most noticeable was cursor.
