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.
