[merged mm-stable] powerpc-hugetlb-pte_alloc_huge.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: powerpc/hugetlb: pte_alloc_huge()
has been removed from the -mm tree.  Its filename was
     powerpc-hugetlb-pte_alloc_huge.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

pte_alloc_map() expects to be followed by pte_unmap(), but hugetlb omits
that: to keep balance in future, use the recently added pte_alloc_huge()
instead.  huge_pte_offset() is using __find_linux_pte(), which is using
pte_offset_kernel() - don't rename that to _huge, it's more complicated.
