| 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. |

| 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. |
