[PATCH 0/2] refactor shmem_get_unmapped_area()

[Toshi Kani]

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.
