From b3f827cb0fe0660c2eacea2c2f9bdb1f225ff768 Mon Sep 17 00:00:00 2001 From: Ananth N Mavinakayanahalli Date: Mon, 2 Oct 2006 02:17:31 -0700 Subject: [PATCH] Add regs_return_value() helper Add the regs_return_value() macro to extract the return value in an architecture agnostic manner, given the pt_regs. Other architecture maintainers may want to add similar helpers.
