Right, "settle down" being the key here.
Matt just mentioned on IRC that we might not need boot services mappings
by the time we have to start the kexec kernel, which would mean, you
don't have to do anything in efi_reserve_boot_services().
The question which needs answering first though is, how the whole efi
thing is going to handle any functionality like calling into efi boot
regions from runtime functions and such. Which hasn't really been tested
and fw vendors don't really want to support that. But this is all bits
and pieces I heard yesterday so it is all pretty wet and I'll let efi
guys, i.e. the Matts and a couple of others :-), figure out this whole
issue.
