Side note: it wasn't entirely obvious what restricted the ghes driver
to only x86 and arm64. I had to look up the whole HAVE_ACPI_APEI
dependency.

So it might be worth mentioning in the commit message why it's ok to
only add the fixmap entries for those two architectures and why it's
not an issue for anything else.
