Subject: [PATCH 2/2] process: change from __backtrace to dump_stack_regs in show_regs
Date: Wed, 24 Aug 2011 10:21:47 -0700	[thread overview]
Message-ID: <1314206507-6487-3-git-send-email-lauraa@codeaurora.org> (raw)
In-Reply-To: <1314206507-6487-1-git-send-email-lauraa@codeaurora.org>

Currently, show_regs calls __backtrace which does
nothing if CONIFG_FRAME_POINTER is not set. Switch to
dump_stack_regs to show the backtrace from a given
set of registers.
