Thanks Leo. However, I've now written a python script that given a
patch directory will run:

foreach patch in dir
     git am patch
     build

so that can work directly on patches before they are sent - or when
they are received in future.

perf/core and perf-tools-next are both on the same commit.
v9 tested against perf/core
