      perf script: Use the default lost event handler · 6d8afb56
      Arnaldo Carvalho de Melo authored 
      That already does what was being done here. The warning is now unconditionally
given by __perf_session__process_pipe_events, just like for non pipe processing.

      perf tools: Fix perf_event.h header usage · d030260a
      Stephane Eranian authored 
      This patch fixes the usage of the perf_event.h header file
between command modules and the supporting code in util.

It is necessary to ensure that ALL files use the SAME
perf_event.h header from the kernel source tree.

There were a couple of #include <linux/perf_event.h> mixed
with #include "../../perf_event.h".

This caused issues on some distros because of mismatch
in the layout of struct perf_event_attr. That eventually
led perf stat to segfault.

      perf test: Clarify some error reports in the open syscall test · 454a3bbe
      Arnaldo Carvalho de Melo authored 
      Rebooted my devel machine, first thing I ran was perf test, that expects
debugfs to be mounted, test fails. Be more clear about it.

Also add missing newlines and add more informative message when
sys_perf_event_open fails.
