If ACPI_APEI and MEMORY_FAILURE is configured, select
ACPI_APEI_MEMORY_FAILURE. This enables memory failure recovery
when such memory failure is reported through ACPI APEI. APEI
(ACPI Platform Error Interfaces) provides a means for the
platform to convey error information to the kernel.
Declare ARCH_SUPPORTS_MEMORY_FAILURE, as arm64 does support
memory failure recovery attempt.

Although enabling support for memory failure handling makes sense in the
architecture config, it feels out of place to select
ACPI_APEI_MEMORY_FAILURE here.
Maybe key it off of CONFIG_APEI?
Yes, I can move it there.
config ACPI_APEI
bool "ACPI Platform Error Interface (APEI)"
select MISC_FILESYSTEMS
select PSTORE
select UEFI_CPER
+ select ACPI_APEI_MEMORY_FAILURE if MEMORY_FAILURE
depends on HAVE_ACPI_APEI
The ARCH_SUPPORTS_MEMORY_FAILURE should remain in arch/arm64/Kconfig
though, correct?
Thanks,
Tyler
