Subject: [PATCH] perf x86: Fix compile of util/tsc.c
Date: Fri, 26 Jul 2013 08:27:23 -0600	[thread overview]
Message-ID: <1374848843-43127-1-git-send-email-dsahern@gmail.com> (raw)

On Fedora 18, with gcc 4.6.4 compile fails with:

arch/x86/util/tsc.c: In function ‘perf_time_to_tsc’:
arch/x86/util/tsc.c:13:6: error: declaration of ‘time’ shadows a global declaration [-Werror=shadow]
cc1: all warnings being treated as errors
make: *** [/tmp/junk/arch/x86/util/tsc.o] Error 1
make: *** Waiting for unfinished jobs....

Fix by renaming the local variable.
