Subject: [PATCH v11 1/7] ARM: probes: move all probe code to dedicate directory
Date: Mon, 1 Dec 2014 16:48:15 +0800 [thread overview]
Message-ID: <1417423695-47521-1-git-send-email-wangnan0@huawei.com> (raw)
In-Reply-To: <1417423513-47161-1-git-send-email-wangnan0@huawei.com>
In discussion on LKML (https://lkml.org/lkml/2014/11/28/158), Russell
King suggest to move all probe related code to arch/arm/probes. This
patch do the work. Due to dependency on 'arch/arm/kernel/patch.h', this
patch also move patch.h to 'arch/arm/include/asm/patch.h', and related
'#include' directive are also midified to '#include <asm/patch.h>'.
