[PATCH v3 0/7] x86: Pile o' FS/GS changes

Hi all- This whole mess is intended for x86/urgent. It fixes several bugs. It's probably a tiny performance regression on some workloads on Intel CPUs. It's probably varies between a less tiny regression and a small speedup on newer AMD CPUs. It's a bigger regression on AMD K8. The AMD code
