Toshi Kani 6fcb523eaf x86/mm: Fix vmalloc_fault to use pXd_large 
commit 18a955219b upstream.

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.  ioremap() does not depend on CONFIG_HUGETLBFS.

Fix vmalloc_fault() to call pXd_large() instead.
