This series looks good to me and I tested:

  - Confirmed no any change for standard CTI;
  - Perf command;
  - Build bisection.

Mike may also want to take a look in case there is any overlap with his
claim tags init patch [1]. I don't have a strong preference on which
series goes in first, as the claim tag handling in this series looks
clean enough to me.

@Yingchao, just a small suggestion: rc1–rc4 is usually the best window
for getting patches merged. If you receive comments and are able to
address them quickly, it may be worth respin patches during that
period to try catching the next merge window. This is no guarantees,
just thought it might be useful to share as a general tip :)
