[PATCH] shrink struct page
Reduce the size of the pageframe for NR_CPUS>4, CONFIG_PREEMPT back to the minimal size by unionising both ->private and ->mapping with the pagetable lock. It uses an anonymous struct and hence requires gcc-3.x. Cc: Hugh Dickins <hugh@veritas.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
