+Subject: arm64/acpi: Add fixup for HPE m400 quirks
+Forwarded: https://patchwork.codeaurora.org/patch/547277/
+
+Adds a new ACPI init routine acpi_fixup_m400_quirks that adds
+a work-around for HPE ProLiant m400 APEI firmware problems.
+
+The work-around disables APEI when CONFIG_ACPI_APEI is set and
+m400 firmware is detected.  Without this fixup m400 systems
+experience errors like these on startup:
+
+  [Hardware Error]: Hardware error from APEI Generic Hardware Error Source: 2
+  [Hardware Error]: event severity: fatal
+  [Hardware Error]:  Error 0, type: fatal
+  [Hardware Error]:   section_type: memory error
+  [Hardware Error]:   error_status: 0x0000000000001300
+  [Hardware Error]:   error_type: 10, invalid address
+  Kernel panic - not syncing: Fatal hardware error!
