Subject: [GIT PULL] x86/urgent fixes for v3.5

Linus,

Please pull the latest x86-urgent-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-urgent-for-linus

   HEAD: b2d668da9307c4c163dd603d2bb3cadb10f9fd37 x86, relocs: Build clean fix

These are the fixes left over from the very end of the v3.4 
stabilization cycle, plus one more fix.

 Thanks,

	Ingo
