Currently APEI depends on x86 architecture. It is because of NMI hardware error notification of GHES which is currently supported by x86 only. However, many other APEI features can be still used perfectly by other architectures. This commit adds two symbols: 1. HAVE_ACPI_APEI for those archs which support APEI. 2. HAVE_ACPI_APEI_NMI which is used for NMI code isolation in ghes.c file. NMI related data and functions are grouped so they can be wrapped inside one #ifdef section. Appropriate function stubs are provided for !NMI case. Note there is no functional changes for x86 due to hard selected HAVE_ACPI_APEI and HAVE_ACPI_APEI_NMI symbols.

APEI allows to report errors (for example from the chipset)
|
|
to the operating system. This improves NMI handling
|
|
especially. In addition it supports error serialization and
|
|
error injection.

Generic Hardware Error Source provides a way to report
|
|
platform hardware errors (such as that from chipset). It
|
|
works in so called "Firmware First" mode, that is, hardware
|
|
errors are reported to firmware firstly, then reported to
|
|
Linux by firmware. This way, some non-standard hardware
|
|
error registers or non-standard hardware link can be checked
|
|
by firmware to produce more valuable hardware error
|
|
information for Linux.

ERST is a way provided by APEI to save and retrieve hardware

error information to and from a persistent store. Enable this

if you want to debugging and testing the ERST kernel support

and firmware implementation.
