ipc/compat_sys_msgrcv: change msgtyp type from long to compat_long_t
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. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
