[PATCH] spufs: fix local store page refcounting
With the new rules for reserved pages, the spufs now needs working page reference counting. I should probably look into converting to vm_insert_page, but for now this patch makes spufs work again. Signed-off-by: Arnd Bergmann <arndb@de.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
