All warnings (new ones prefixed by >>):
warning: (ACPI_APEI) selects EFI which has unmet direct dependencies (OF && !CPU_BIG_ENDIAN)
I think it's caused by CPU_BIG_ENDIAN, because ARM64 selects OF.
No, as I pointed out, it is caused by the fact that you 'select' EFI rather than 'depend on' it.
Any suggestion ?
replace
select EFI if ARM64
with
depends on EFI || !ARM64
but it would be even better to make ACPI_APEI depend on ACPI, since the above dependency will be implied then, although I am not sure how that affects other architectures.
