[PATCH 0/2] x86/mm: vmalloc_fault fix for CONFIG_HUGETLBFS off

[Toshi Kani]

Gratian Crisan reported that vmalloc_fault() crashes when
CONFIG_HUGETLBFS is not set since the function inadvertently
uses pXn_huge(), which always return 0 in this case. [1]
ioremap() does not depend on CONFIG_HUGETLBFS.

Patch 01 fixes the issue in vmalloc_fault().
Patch 02 is a clean-up for vmalloc_fault().
