Tom, could you have a go at rebasing this patch on top of the 'chainsaw'
branch at,
git://git.kernel.org/pub/scm/linux/kernel/git/mfleming/linux.git
Though, instead of drivers/firmware/efisubsys.c just put the core stuff
in drivers/firmware/efi/efi.c. The efivar_entry() API code should
probably be moved to drivers/firmware/efi/variable.c or
drivers/firmware/efi/vars.c, etc. That way, we can finally delete
efivars.c and have all the EFI code under drivers/firmware/efi/.
Make sense?
P.s I ended up dropping your MODULE_ALIAS() patch on this branch because
I feel that moving the efivarfs code into fs/efivarfs is a better way to
fix up the confusion that efivars != efivarfs, plus building fs/efivarfs
as a module results in an efivarfs.ko file ;-)
