Message-ID: <20120521185202.GA6486@merkur.ravnborg.org> Date: Mon, 21 May 2012 20:52:02 +0200 From: Sam Ravnborg <sam@...nborg.org> To: Linus Torvalds <torvalds@...ux-foundation.org>, netdev <netdev@...r.kernel.org>, "David S. Miller" <davem@...emloft.net> Cc: David Miller <davem@...emloft.net>, akpm@...ux-foundation.org, sparclinux@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH] net: drop NET dependency from HAVE_BPF_JIT >From 4976b8fc9fd9f876634d6d73e5b808c762e1352a Mon Sep 17 00:00:00 2001 From: Sam Ravnborg <sam@...nborg.org> Date: Mon, 21 May 2012 20:45:37 +0200 Subject: [PATCH] net: drop NET dependency from HAVE_BPF_JIT There is no point having the NET dependency on the select target, as it forces all users to depend on NET to tell they support BPF_JIT. Move the config option to the bottom of the file - this could be a nice place also for future "selectable" config symbols. Fix up all users to drop the dependency on NET now that it is not required to supress warnings for non-NET builds. Reported-by: Linus Torvalds <torvalds@...ux-foundation.org> Signed-off-by: Sam Ravnborg <sam@...nborg.org> --- Did a few "make ARCH=xxx allnoconfig" and no warning were triggered.
