Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86/urgent branch from Ingo Molnar: "These are the fixes left over from the very end of the v3.4 stabilization cycle, plus one more fix." Ugh. Those KERN_CONT additions are just pointless. I think they came as a reaction to some of the early (broken) printk() work - but that was fixed before it was merged. * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, relocs: Build clean fix x86, printk: Add missing KERN_CONT to NMI selftest x86: Fix boot on Twinhead H12Y
