As the confusing naming indicates, this test has some overlap with
pre-existing tests. Would be nice to merge them eventually. But since it
is only test code, cleanliness is much less important than mere existence.Signed-off-by: Joern Engel

On platforms with C8-C10 support, the additional C-states cause
turbostat to overrun its output buffer of 128 bytes per CPU. Increase
this to 256 bytes per CPU.[ As a bugfix, this should go into 3.10; however, since the C8-C10
support didn't go in until after 3.9, this need not go into any stable
kernel. ]Signed-off-by: Josh Triplett

We have a one of the event open fallback case in __perf_evsel__open
where we zero exclude_guest|exclude_host fields.This means there's no way for attr tests to find out what's the right
value for those fields, so we need to check for both 0 and 1. Luckily we
still have other event parsing tests for those fields.Signed-off-by: Jiri Olsa
