Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fix from Thomas Gleixner:
"A single fix for vmalloc_fault() which uses p*d_huge() unconditionally
whether CONFIG_HUGETLBFS is set or not. In case of CONFIG_HUGETLBFS=n
this results in a crash as p*d_huge() returns 0 in that case"
