Merge tag 'amd_severity' of git://git.kernel.org/pub/scm/linux/kernel/git/ras/ras into x86/ras

Pull RAS update from Borislav Petkov:

  "This has been long in the making - an AMD-specific MCE-severity grading
   function. And it is actually readable at a quick glance. Further error
   recovery actions will be based on its output.

   Patches tested on every relevant AMD family out there."
