From 91854f9a077e18e43ed30ebe9c61f8089bec9166 Mon Sep 17 00:00:00 2001
From: Arnaldo Carvalho de Melo <acme@redhat.com>
Date: Thu, 29 Aug 2019 14:59:50 -0300
Subject: [PATCH] perf tools: Move everything related to sys_perf_event_open()
 to perf-sys.h

And remove unneeded include directives from perf-sys.h to prune the
header dependency tree.

Fixup the fallout in places where definitions were being used without
the needed include directives that were being satisfied because they
were in perf-sys.h.
