From 4602761bac19ae3373f003bc3cabc4546c8e5207 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Tue, 4 Mar 2014 12:39:03 +0100 Subject: ipc/compat_sys_msgrcv: change msgtyp type from long to compat_long_t commit 291fdb0bcebd5e8db6af767c1fdc522167dad73d upstream. Change the type of compat_sys_msgrcv's msgtyp parameter from long to compat_long_t, since compat user space passes only a 32 bit signed value. Let the compat wrapper do proper sign extension to 64 bit of this parameter.
