As above, this is a run against plain -rc4 in preparation for testing the
5.14 queue on top to detect any regressions.

The two tests failing here are 'statx04' and 'hugeshmat04':

(grep for FAIL). I've not had a chance to dig into them yet.

This explodes pretty badly. Some CPUs detect RCU stalls when trying to use
the EFI "efi_read_time" service, which eventually fails but soon after we
explode trying to access memory which I think is mapped by
acpi_os_ioremap(), so it looks like the f/w might be the culprit here. Is
the "HPE Apollo 70" machine known to have bad EFI firmware?

(scroll to the end for the fireworks)
