From: Sukadev Bhattiprolu <suka...@linux.vnet.ibm.com>
We print several '__u64' quantities using '%llu'. On powerpc, we by
default include '<asm-generic/int-l64.h> which results in __u64 being an
unsigned long. This causes compile warnings which are treated as errors
due to '-Werror'.
By defining __SANE_USERSPACE_TYPES__ we include <asm-generic/int-ll64.h>
and define __u64 as unsigned long long.
Changelog[v2]:
[Michael Ellerman] Use __SANE_USERSPACE_TYPES__ and avoid PRIu64
format specifier - which as Jiri Olsa pointed out, breaks on x86-64.
