Hi Tomasz,

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.
