AFAICT, you should simply do

/* Order of pages in page cache */
#define PAGE_CACHE_PAGE_ORDER 0

#define PAGE_CACHE_SHIFT (PAGE_SHIFT + PAGE_CACHE_PAGE_ORDER)
#define PAGE_CACHE_SIZE (1 << PAGE_CACHE_SHIFT)
#define PAGE_CACHE_MASK (~(PAGE_CACHE_SIZE-1))
#define PAGE_CACHE_ALIGN(addr) (((addr)+PAGE_CACHE_SIZE-1)&PAGE_CACHE_MASK)

*Then* fix up the misuses,
Rusty.
