Please disregard all these sha1's for the time being, as a regression has just been bisected back to:

Ok, should I just ignore all of these then? Don't you want the other patches before that one merged?

Yeah, so you can apply:

2f993cf09364 ("perf: Fix ring_buffer_attach() RCU sync, again") 4b36f1a4139c ("perf/x86: Add more Broadwell model numbers") 6b099d9b040b ("perf/x86/intel/bts: Fix DS area sharing with x86_pmu events")

And in fact you can apply these two too:

2c33645d366d ("perf/x86: Honor the architectural performance monitoring version") 75e84ab906ef ("perf tools: Fix build breakage if prefix= is specified")

as they are independent.

It's only 1b7b938f1817 that was borked.
