Subject: [PATCH 0/2] refactor shmem_get_unmapped_area()

shmem_get_unmapped_area() provides a functionality similar
to __thp_get_unmapped_area() as both allocate a pmd-aligned
address.  This patchset changes shmem_get_unmapped_area()
to call __thp_get_unmapped_area() to share the code.

Patch 1 fixes a bug in shmem_get_unmapped_area() first.
Patch 2 changes shmem_get_unmapped_area() to call
__thp_get_unmapped_area() for sharing the code.

This patch-set applies on top of my patchset below.

Toshi Kani (2):
 1/2 shmem: fix tmpfs to handle the huge= option properly
 2/2 shmem: call __thp_get_unmapped_area to alloc a pmd-aligned addr
