Subject: perf/compat: Fill in new definitions for madvise()/mmap() flags
Date: Thu, 12 Sep 2013 15:29:00 +0200 [thread overview]
Message-ID: <20130912132900.GE23826@gmail.com> (raw)
In-Reply-To: <tip-w28d1o3uslden0k57653kda7@git.kernel.org>
builtin-trace.c started using various new syscall features not defined in
the header files of older distros - resulting in build failures.
Fill in the (ABI) constants if they are not defined.
(There might be a better place to put this than builtin-trace.c, into a
compat header or so.)
