[GIT PULL] EFI runtime mapping work for v3.14

[GIT PULL] EFI runtime mapping work for v3.14

[Matt Fleming]

Folks, could you queue up the following for the v3.14 merge window? It
would be good to get these patches into linux-next for a full release
cycle of testing. They pass all of my tests.

The following changes since commit 72548e836b0c4abbb652e791dee9c91203a9a4c6:

  x86/efi: Add EFI framebuffer earlyprintk support (2013-10-28 18:09:58 +0000)

Pulled into tip:x86/efi, thanks a lot guys!

Just a side note, for future reference, this title lacks a verb and is 
thus not self-describing:

   x86/efi: Runtime services virtual mapping

It should probably have been something like:

   x86/efi: Implement and enable separate, stable virtual mapping for runtime services

?

Chances are that it will be a popular bisection target ;-)

My bad: it should've been "Reimplement runtime services virtual mapping"
or sth like that.

I *so* hope your clairvoyant skills fail you this time :-)

Mind resending this in about a week or so? The merge window has just 
started and we don't want to potentially destabilize -next with v3.14 
problems.

Thanks,
