Subject: [PATCH v5 02/16] ARM: move shared uprobe/kprobe definitions into new include file
Date: Thu, 23 Jan 2014 15:05:45 -0500 [thread overview]
Message-ID: <1390507559-4697-3-git-send-email-dave.long@linaro.org> (raw)
In-Reply-To: <1390507559-4697-1-git-send-email-dave.long@linaro.org>
From: "David A. Long" <dave.long@linaro.org>
Separate the kprobe-only definitions from the definitions needed by
both kprobes and uprobes.
Signed-off-by: David A. Long <dave.long@linaro.org>
