[PATCH] powerpc: fix CONFIG_SWAP=n builds for 64-bit

[Jeremy Kerr <jk@ozlabs.org>]

Currently, 64-bit won't build with CONFIG_SWAP=n, as asm-generic/tlb.h
needs page_cache_release() and release_pages(), which are defined in
linux/pagemap.h.

We can't include linux/pagemap.h in asm-generic/tlb.h, as (apparently)
this breaks sparc. So, include it in the necessary places in the
powerpc mm code.
