This is all derived from Scott Bauer's x86 patches (https://lkml.org/lkml/2016/3/29/788). Have tested rc5 with these patches on: 
	- BE VM
	- BE bare metal
	- LE VM
	- LE bare metal

with the Linux Test Project runltp test script with all default configs. From rc5 to rc5 with these patches no new tests failed. 

Any comments/suggestions are welcome!
