From: David S. Miller Date: Fri, 13 Apr 2007 20:27:08 +0000 (-0700) Subject: [SPARC64]: Fix arg passing to compat_sys_ipc(). X-Git-Tag: v2.6.21-rc7~10^2~1 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5c7aa6ffae514bfeb7ec0f249dde949863d895ac;p=linux-2.6 [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.
