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.

Yap, looks ok to me: we're basically enabling
ghes_handle_memory_failure() to queue a memory address at fault for
possibly offlining on arm64. And since the arch supports it...
