[PATCH V2] arm64: kconfig: allow support for memory failure handling

From: Tyler Baicar
Date: Tue Feb 21 2017 - 18:45:39 EST


From: "Jonathan (Zhixiong) Zhang" <zjzhang@xxxxxxxxxxxxxx>

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.

APEI allows to report errors (for example from the chipset)
