Subject: [PATCH] x86/tsc: remove the unused check_tsc_disabled()
Date: Fri, 15 Jul 2016 16:12:10 +0800 [thread overview]
Message-ID: <1468570330-25810-1-git-send-email-weijg.fnst@cn.fujitsu.com> (raw)
check_tsc_disabled() was introduced by commit c73deb6aecda ("perf/x86:
Add ability to calculate TSC from perf sample timestamps").
The only caller arch_perf_update_userpage() had been refactored
by commit fa9cbf320e99 ("perf/x86: Move perf_event.c ...............
=> x86/events/core.c").
so no need keep and export it any more.
