Subject: [PATCH v2 15/23] Oops: Pass regs to oops_exit()
Date: Mon, 08 Nov 2010 12:33:05 -0800	[thread overview]
Message-ID: <20101108203304.22479.93234.stgit@crlf.mtv.corp.google.com> (raw)
In-Reply-To: <20101108203120.22479.19708.stgit@crlf.mtv.corp.google.com>

Later commits in this series will want to see pt_regs if available when a
machine oopses.  Pass regs if available on to oops_exit().
