[PATCH] remove show_buffers()

Remove show_buffers().  It really has nothing to show any more.  just
buffermem_pages() - move that out into the callers.

There's a lot of duplication in this code.  better approach would be to
remove all the duplicated code out in the architectures and implement
generic show_memory_state().  Later.
