[PATCH 0/8] Decode IA32/X64 CPER

[Yazen Ghannam]

From: Yazen Ghannam <yazen.ghannam@xxxxxxx>

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.

Without basic decoding, users will be confused about what these
"Hardware Errors" mean. So I'm requesting this set to be applied to the
stable branches. This set applies to the v4.16. However, patch 2 will
have a conflict on older branches, so I'll send this set again with the
conflict fixed.

Thanks,
Yazen
