Add:
#include <linux/mempolicy.h>
to that file and it should build.

Yeah, that's a known trainwreck, some archs define u64 as unsigned long
others as unsigned long long, so whatever you write: %ul or %ull is
wrong and I can't be arsed to add an explict cast since its all debug
bits that won't ever make it in anyway.
