Subject: Re: [GIT PULL 0/4] perf/urgent fixes
Hi Arnaldo,
I've set up some docker containers for build test, and found a couple
of failures.. It seems David's kmem build fix ("perf kmem: Fix
compiles on RHEL6/OL6") which is in your perf/core branch also needs
to be in perf/urgent. Sorry about the kmem breakages..
And I also found this..

Subject: [PATCH] tools lib traceevent: Fix build failure on 32-bit arch
In my i386 build, it failed like this:
CC event-parse.o
event-parse.c: In function 'print_str_arg':
event-parse.c:3868:5: warning: format '%lu' expects argument of type 'long unsigned int',
but argument 3 has type 'uint64_t' [-Wformat]
