Subject: [RFC PATCH v2 0/4] acpi: apei: Improve error handling with firmware-first

Or "acpi: apei: Don't let puny firmware crash us with puny errors"

This is the improved implementation following feedback from James Morse
(thanks James!). This implementation, I think, is more modular, and easier to
follow, and just makes more sense.

I'm leaving this as RFC because the BIOS team is a bit scared of an OS
that won't crash when it's told to. However, if people like the idea, then
I have nothing against merging this.

Changes since v1:
 - Due to popular request, the panic() is left in the NMI handler
 - GHES AER handler is split into NMI and non-NMI portions
 - ghes_notify_nmi() does not panic on deferrable errors
 - The handlers are put in a mapping and given a common call signature

Alexandru Gagniuc (4):
  EDAC, GHES: Remove unused argument to ghes_edac_report_mem_error
  acpi: apei: Split GHES handlers outside of ghes_do_proc
  acpi: apei: Do not panic() when correctable errors are marked as
    fatal.
  acpi: apei: Warn when GHES marks correctable errors as "fatal"
