[PATCH v3 0/2] x86/fault: Further improve #PF oops messages

[Sean Christopherson <sean.j.christopherson@intel.com>]

Rework the messages printed for #PF oopses to display more detailed
information about the fault in human readable form and to avoid
conflicting messages and/or statements that may not always be accurate.

v3:
  - Prepend a patch to reword the initial BUG message
  - Add sample output in the changelogs
  - Swap the order of the #PF lines.  For most cases the three main lines
    show up in reverse fir-tree ordering and the cause of the fault is
    easy to pick out since it's the last thing highlighted by pr_alert
    (excepting when dumping the IDT, GDT, etc...).

v2:
  - Explicitly call out protection keys violations
  - "Slightly" reword the changelog

v2: https://lkml.kernel.org/r/20181207184423.1962-1-sean.j.christopherson@intel.com
