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.
