| |
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
v1: https://lkml.kernel.org/r/20181207195223.23968-1-sean.j.christopherson@intel.com v2: https://lkml.kernel.org/r/20181207184423.1962-1-sean.j.christopherson@intel.com
