I applied the original patch from Bagas. I'm looking at
arch/x86/boot.html. It shows me:

1.16. PE/COFF entry point

  When compiled with CONFIG_EFI_STUB=y, the kernel can be executed as a regular PE/COFF binary. See The EFI Boot Stub for implementation details.

where "The EFI Boot Stub" is (in my browser) in blue and underlined and is a link to
admin-guide/efi-stub.html


Is this what you are saying will not happen or am I
completely confused?  Kernel documentation automarkup handles
Documentation/.../*.rst file links automatically.
