Revision 0a7c10df49eb69dd888ea8b8ddd29bde2aa2fd48 authored by Linus Torvalds on 14 March 2021, 19:48:10 UTC, committed by Linus Torvalds on 14 March 2021, 19:48:10 UTC
Pull x86 fixes from Borislav Petkov:

 - 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.
