Subject: [PATCH] arm: show_regs dump stack when ARM_UNWIND enable
Date: Thu, 22 Jul 2010 01:24:28 +0800	[thread overview]
Message-ID: <20100721172428.GA5881@localhost.localdomain> (raw)
In-Reply-To: <1279704065.17464.1.camel@e102109-lin.cambridge.arm.com>

Is there any way for arm unwind to do user space backtrace like c_backtrace in arm_syscall?

Thanks
