Add /proc/kpagemap interface
This makes physical page flags and counts available to userspace.
Together with /proc/pid/pagemap and /proc/pid/clear_refs, this can be

Add /proc/pid/pagemap interface
This interface provides a mapping for each page in an address space to

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 m
