Linus Torvalds 8363e795eb A first set of urgent fixes to the FPU/XSTATE handling mess^W code.

(There's a lot more in the pipe):
 
 - Prevent corruption of the XSTATE buffer in signal handling by
   validating what is being copied from userspace first.
 
 - Invalidate other task's preserved FPU registers on XRSTOR failure
   (#PF) because latter can still modify some of them.
 
 - Restore the proper PKRU value in case userspace modified it
 
 - Reset FPU state when signal restoring fails
 
 Other:
 
 - Map EFI boot services data memory as encrypted in a SEV guest so that
   the guest can access it and actually boot properly
 
 - Two SGX correctness fixes: proper resources freeing and a NUMA fix
