Let's keep this function for now. This function is used in my version
11 of mmu enabled kexec patches; but not used in version 12 where we
changed to a linear map instead of contiguous map. However, until the
final solution for mmu-enabled kexec lands in the mainline, I think it
is better to keep it.

Thank you,
