mm/FRV: use free_highmem_page() to free highmem pages into buddy system
Jiang Liu [Mon, 29 Apr 2013 22:07:04 +0000 (15:07 -0700)]
Use helper function free_highmem_page() to free highmem pages into
the buddy system.

Also fix a bug that totalhigh_pages should be increased when freeing
a highmem page into the buddy system.
