Hi,
The commit:
commit d72da4a4d973d8a0a0d3c97e7cdebf287fbe3a99
Author: Peter Zijlstra <pet...@infradead.org>

rbtree: Make lockless searches non-fatal
Adds <linux/rcupdate.h> to rbtree.h, which in turn is included from perf
userspace
headers. Now building tools/perf will fail with hundreds of lines of gcc
complaining
about kernel defines not available. Reverting the patch makes perf build again.
This is with gcc-4.9 from debian but I don't think it's compiler specific.
Beginning of build error:
$ make -C tools/perf
make: Entering directory '/build/linux/tools/perf'
BUILD: Doing 'make -j4' parallel build
