Also this patchset doesn't seem to apply to tip/perf/core, v4.3-rc3,
v4.2. What is it based on? Do you have a git branch with these patches
as well?

The kernel space portion applied to v4.3-rc1.  I had to keep the user
space side on a private branch based on v4.2 since v4.3-rc1 didn't
have a few fix from Adrian.  V2 will be based on v4.3-rc4 and have all
the patches (user and kernel space) on the same tree.
