For future reference you should really use a shorter first line in your
git commit message, which would produe a shorter subject when mailing
your patches.
I'll fix up the commit messages when I apply these patches, so don't
worry about it for now.

Hmm... I'm not necessarily convinced this is an improvement over using
some kind of a global pointer to the EFI System Table.
Parameterizing stuff like this is useful when the argument changes at
runtime from call to call, but that isn't the case for the boot stubs. I
don't think there's anything wrong with a global in this scenario, and
this patch is a fair amount of churn for no real improvement.
