So now I get:

[acme@...et perf]$ make -C tools/perf
make: Entering directory '/home/acme/git/perf/tools/perf'
  BUILD:   Doing 'make -j4' parallel build
Warning: Kernel ABI header at 'tools/include/linux/coresight-pmu.h' differs from latest version at 'include/linux/coresight-pmu.h'
  INSTALL  GTK UI
  INSTALL  trace_plugin
<SNIP>

You should either send the patch to both files or first send it to the
kernel, then to tools/, I just checked and this SPDX using
coresight-pmu.h file hasn't hit upstream, so we're in the future here,
i.e. tools/include has a _copy_ of what is in include/ :-)

I'm dropping this patch from my tree till this gets resolved.
