Hi,
Function efi_memory_present_wrapper parameter start/end is physical address,
but function memory_present parameter is PFN, this patch converts physical
address to PFN.

It doesn't _seem_ like a "minor error". How come people's machines haven't
been crashing all over the place?
This patch is only efi bios relative, most machines in the market are
legacy bios. System only crashes when booting from EFI bios.
thanks
