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 Hanjun
