Subject[PATCH 0/3] tracing/perf: perf_trace_buf/perf_xxx hacks.
Hello.

On top of "PATCH 0/3] tracing: more list_empty(perf_events) checks"
series I sent yesterday.

Compile tested only, not for inclusion yet.

But I'll appreciate if you can take a look. I'll try to test this
tomorrow somehow and let you know. Right now I am looking at asm code,
looks correct...

I also compiled the kernel with the additional patch below, everything
compiles except sched/core.o as expected.

Oleg.
