This patch series introduces /proc/pid/pagemap and /proc/kpagemap, which allow
detailed run-time examination of process memory usage at a page granularity.

The first several patches whip the page-walking code introduced for
/proc/pid/smaps and clear_refs into a more generic form, the next couple make
those interfaces optional, and the last two introduce the new interfaces, also
optional.

This respin adds simple, expandable headers to both pagemap and kpagemap as
suggested by Nikita.  I haven't moved pagewalk.c from lib/ to mm/ as suggested
by Nick as I still think lib is a better fit for its automatic conditional
linking.

This patch:

Uninline some functions in the page walker
