Sounds great. I'll hold off with sending my RFT series and wait for your
test results. I think we'll also need d367cef0a7f0c6 ("x86/mm/pat: Fix
boot crash when 1GB pages are not supported by the CPU").

Sure, makes sense - I don't have any EFI systems with CPUs old enough
not to support 1G pages but that looks reasonable.  I'll pull that
into my tree as well.

kernelci reported a crash on a CPU which doesn't support 1G pages.
See https://kernelci.org/boot/id/5b7d39ea59b514c03796ba9c/
