X-Git-Tag: upstream/snapshot3+hdmi~5281^2~83

mm/FRV: use free_highmem_page() to free highmem pages into buddy system

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.
