These look good to me; but at the same time Kan is sending me
Architectural LBR patches.

Kan, if I take these perf patches and stick them in a tip/perf/vlbr
topic branch, can you rebase the arch lbr stuff on top, or is there
anything in the arch-lbr series that badly conflicts with this work?

Yes, I can rebase the arch lbr patches on top of them.
Please push the tip/perf/vlbr branch, so I can pull and rebase my patches.
For now I have:

   git://git.kernel.org/pub/scm/linux/kernel/git/peterz/queue.git perf/vlbr

Once the 0day robot comes back all-green, I'll push it out to
tip/perf/vlbr and merge it into tip/perf/core.
tip/perf/vlbr now exists, thanks!
Hi Peter,

Thanks for your patience and professional support on this feature!

Thanks,
Like Xu
