Linus Torvalds 0a7c10df49 - A couple of SEV-ES fixes and robustifications: verify usermode stack 
pointer in NMI is not coming from the syscall gap, correctly track IRQ
 states in the #VC handler and access user insn bytes atomically in same
 handler as latter cannot sleep.
 
 - Balance 32-bit fast syscall exit path to do the proper work on exit
 and thus not confuse audit and ptrace frameworks.
 
 - Two fixes for the ORC unwinder going "off the rails" into KASAN
 redzones and when ORC data is missing.
