From 8520a98dbab61e9e340cdfb72dd17ccc8a98961e Mon Sep 17 00:00:00 2001
From: Arnaldo Carvalho de Melo <acme@redhat.com>
Date: Thu, 29 Aug 2019 16:18:59 -0300
Subject: [PATCH] perf debug: Remove needless include directives from debug.h

All we need there is a forward declaration for 'union perf_event', so
remove it from there and add missing header directives in places using
things from this indirect include.
