[PATCH] mm: use unsigned long constant for page flags

struct page->flags is unsigned long, so when shifting bits we should use UL suffix to match it. Found this problem after I added 64-bit CPU specific page flags and failed to compile the kernel: mm/page_alloc.c: In function '__free_one_page': mm/page_alloc.c:672:2: error: integer overflow in
