OK Dave, I've pulled patches 3-12 into the 'kexec' branch at,

  git://git.kernel.org/pub/scm/linux/kernel/git/mfleming/efi.git

I plan on sending this branch to the tip folks this week for further
testing.

Please have a look and make sure I haven't messed anything up when
dropping the first two patches (though they were very small and trival).

Toshi, if you could grab that branch and give it a test, that'd be
excellent.
