From mboxrd@z Thu Jan 1 00:00:00 1970 From: Nicholas Krause Date: Fri, 18 Jul 2014 05:25:02 +0000 Subject: [PATCH] ia64: Fix me add register r8 Message-Id: <1405661102-11967-1-git-send-email-xerofoify@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: tony.luck@intel.com Cc: fenghua.yu@intel.com, linux-ia64@vger.kernel.org, linux-kernel@vger.kernel.org The function user_stack_pointer was not returning the correct value \ as stated by a Fix Me message before the function declaration. I fixed the return value to add register r8 as that register stores dirty pages.
