Public bug reported:
[Impact]
A hardware issue can lead to a kernel crash or unexpected behavior.
[Test Case]
The issue presents itself most commonly as a boot-time crash. It doesn't effect
all Falkor CPUs, and only rarely occurs on CPUs that are effected.
[Regression Risk]
The fix is entirely in arm64 code, mitigating the risk to other architectures.
The biggest regression risk is performance, as the workaround involves adding
an instruction barrier prior to disabling the MMU.
