When a memory error, CPU error, PCIe error, or other type of hardware error
that's covered by RAS occurs, firmware should populate the shared GHES memory
location with the proper GHES structures to notify the OS of the error.
For example, platforms that implement firmware first handling may impleme
A RAS (Reliability, Availability, Serviceability) controller
may be a separate processor running in parallel with OS
execution, and may generate error records for consumption by
the OS. If the RAS controller produces multiple error records,
then they may be overwritten before the OS has consumed th
Add support for ARM Common Platform Error Record (CPER).
UEFI 2.6 specification adds support for ARM specific
processor error information to be reported as part of the
CPER records. This provides more detail on for processor error logs.

Currently external aborts are unsupported by the guest abort
handling. Add handling for SEAs so that the host kernel reports
SEAs which occur in the guest kernel.

Currently when a RAS error is reported it is not timestamped.
The ACPI 6.1 spec adds the timestamp field to the generic error
data entry v3 structure. The timestamp of when the firmware
generated the error is now being reported.

honor the severity level and panic.

SEA exceptions are often caused by an uncorrected hardware

When SEA occurs, before killing the process, report the error

On arm64 PCI systems, the entire PCI hierarchy is reconfigured from
scratch at boot.
