Why do not you define the flag above in this file (move it out of x86 -
that's what I was aiming at in my previous reply) and remove this ifdeffery
altogether (First firmware handling could apply to arm64 too according to
specs and ACPI on arm64 guidelines) ?
If I understand it correctly, CMC (Corrected Machine Check) is for IA32
only, see section 18.3.2.1 IA-32 Architecture Machine Check Exception
in ACPI 6.0. for ARM64, we can use other type of error source for
firmware first handling, such as Generic Hardware Error Source, did
I miss something?
Thanks
