Subject: [PATCH 08/10] perf tools: Move syscall and arch specific defines from perf.h
Date: Mon, 5 May 2014 14:33:37 +0200 [thread overview]
Message-ID: <1399293219-8732-9-git-send-email-jolsa@kernel.org> (raw)
In-Reply-To: <1399293219-8732-1-git-send-email-jolsa@kernel.org>
Into new perf-sys.h header.
The main reason is to separate system specific perf data
from perf tool stuff, so it could be used in small test
programs, as requested Peter:
http://lkml.kernel.org/r/20140502115201.GI30445@twins.programming.kicks-ass.net
This separation makes the perf.h header more clear.
