From 5c7aa6ffae514bfeb7ec0f249dde949863d895ac Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Fri, 13 Apr 2007 13:27:08 -0700 Subject: [PATCH] [SPARC64]: Fix arg passing to compat_sys_ipc(). Do not sign extend args using the sys32_ipc stub, that is buggy and unnecessary. Based upon an excellent report by Mikael Pettersson. Signed-off-by: David S.
