+O-Subject: [RHEL8 BZ1518076 PATCH] ACPI: APEI: arm64: Ignore broken HPE moonshot APEI support
+Bugzilla: 1518076

+Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1518076
+Brew: https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=15417197
+Tested: compile-only; several other patches are required for full booting
+ QE has tested limited boot (see comment#12 of BZ)
+
+This is a re-post of a RHEL-ALT-7.5 patch specific to aarch64 moonshots
+that we use in beaker. It is required for these machines to boot.

+ [acpi] APEI: arm64: Ignore broken HPE moonshot APEI support
+
+ From: Mark Salter <msalter@redhat.com>
+ Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1344237
+ Brew: https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=13768971
+ Tested: Booted on moonshot with patched 4.11.0-20 kernel
+ Upstream: RHEL-only
+
+ The aarch64 HP moonshot platforms we have in beaker and elsewhere have
+ a firmware bug which causes a spurious fatal memory error via APEI at
+ boot time. This platform is no longer supported and no further firmware
+ updates are expected. This is a downstream-only hack to avoid the problem
+ by bailing out of HEST table probing if we detect a moonshot HEST table.
