Subject: [PATCH 0/2] Add machine check recovery for instruction fetch

Part 1 fixes an oversight in the existing code that didn't show
up while I was testing the data recovery case (because I never tried
injecting an error into a clean LRU data page ... only to dirty pages
where "memory_failure()" says we have to SIGBUS the process).

Part simply adds the right entries to the severity table so that we
will recognise instruction fetch faults.

Tony Luck (2):
  x86/mce: Only restart instruction after machine check recovery if it
    is safe
  x86/mce: Add instruction recovery signatures to mce-severity table
