I went trying to clean up the spurious protection key checks. But, I got distracted by some other warts in the code. I hope this makes things more comprehendable with some improved structure, commenting and naming.
We come out the other side of it with a new warning in for pkey faults in the kernel portion of the address space, and removal of some dead pkeys code, but no other functional changes.
There is a potential impact from moving the vsyscall emulation. But, this does pass the x86 selftests without any fuss.
