We map the EFI regions needed for runtime services contiguously on
virtual addresses starting from -4G down for a total max space of 64G.
This way, we provide for stable runtime services addresses across

I can post the kexec related patches after your mapping patches settle
down
Right, settle down

It's incredibly difficult to diagnose early EFI boot issues without
special hardware because earlyprintk=vga doesn't work on EFI systems.
Add support for writing to the EFI framebuffer, via earlyprintk=efi,
which will actually give users a chance of

Also, the main question would be, what is the typical value for

on what graphics state the EFI bootloader passes us?
Microsoft require that it be 32, so in
