[GIT PULL] EFI changes for v3.18

[Matt Fleming <matt-HNK1S37rvNbeXh+fF434Mdi2O/JbrIOy@public.gmane.org>]

Hi guys,

This pull request is coming later than I had intended, sorry about that.
It unfortunately got pushed out by a number of things, chasing bugs,
releases for other projects, etc.

Merging this tag into Linus' tree causes some conflicts, which I've
fixed up and pushed out as the efi-next-merge branch, in case you or
Linus want to take a look at it. The conflicts are fairly straight
forward to resolve.

The following changes since commit 99a5603e2a1f146ac0c6414d8a3669aa749ccff8:

  efi/arm64: Handle missing virtual mapping for UEFI System Table (2014-07-18 21:24:04 +0100)

  x86/efi: Adding efi_printks on memory allocationa and pci.reads (2014-09-28 17:43:21 +0100)

----------------------------------------------------------------
 * Implement new EFI runtime lock which is required by the UEFI
   specification - Ard Biesheuvel

 * Add new efi= x86 EFI boot stub parameter which mimics the way that
   the regular kernel parameter works - Matt Fleming

 * Improve error handling in efi-bgrt driver - Josh Triplett

 * Extend the "noefi" kernel parameter to arm64, add an efi=noruntime
   synonym - Dave Young

 * Beautify the EFI memory map logs - Laszlo Ersek

 * Fix compiler shadow warnings and improve variable names - Mark Rustad

 * Remove unused efi_call() macros, update comments, tag initialization
   functions with __init - Mathias Krause

 * Add more informative efi_printk()s to the x86 EFI boot stub at the
   firmware call-sites - Andre Müller
