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
