It is there already:

⬢[acme@...lbox perf]$ git log --oneline torvalds/master | grep -m1 "Add new IBS register bits into header"
326ecc15c61c349c perf/x86/ibs: Add new IBS register bits into header
⬢[acme@...lbox perf]$

but not the other patches in this series:

⬢[acme@...lbox perf]$ git log --oneline torvalds/master | grep -m1 "amd: Support PERF_SAMPLE_PHY_ADDR"
⬢[acme@...lbox perf]$
