This patch adds PE/COFF header fields to the start of the Image

stub is included to allow direct booting of the kernel Image. Due
to EFI firmware limitations, only little endian kernels with 4K
page sizes are supported at this time. Support in the COFF header
for signed images was provided by Ard Biesheuvel.

You got the ordering of the S-o-b lines wrong. Since you send the
patch, your name should come last.

Why not ARM64_64K_PAGES? I thought that it was going to be the
default for a lot of distros that would need to run on UEFI systems.

Hmm, this is pretty ugly. I notice the same has been done on MIPS
as well, but I'd hope we can find a proper way to do it.

It gets worse here.
