Subject: [PATCH v3 0/8] Decode IA32/X64 CPER

From: Yazen Ghannam <yazen.ghannam@....com>

This series adds decoding for the IA32/X64 Common Platform Error Record.

Patch 1 fixes the IA32/X64 Processor Error Section definition to match
the UEFI spec.

Patches 2-8 add the new decoding. The patches incrementally add the
decoding starting from the top-level "Error Section". Hopefully, this
will make reviewing a bit easier compared to one large patch.

The formatting of the field names and options is taken from the UEFI
spec. I tried to keep everything the same to make searching easier.

The patches were written to the UEFI 2.7 spec though the definition of
the IA32/X64 CPER seems to be the same as when it was introduced in
the UEFI 2.1 spec.

Changes V2 to V3:
* Fix table numbers in commit messages.
* Don't print raw validation bits.
* Only print GUID for unknown error types.

Changes V1 to V2:
* Remove stable request for all patches.
* Address Ard's comments on formatting and other issues.
* In Patch 8, always print context info even if the type is not
  recognized.
