Subject: [GIT PULL] EFI fix

Linus,

Please pull the latest efi-urgent-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git efi-urgent-for-linus

   # HEAD: b12f5440d8ca02e8f9ab4f1461f9214295cc4f66 Merge branch 'linus' into efi/urgent, to resolve conflict

A single fix that adds an annotation to resolve a kmemleak false 
positive.

 Thanks,

	Ingo
