s390/compat: remove superfluous compat wrappers 2015-09-18T09:16:52+00:00 Heiko Carstens heiko.carstens@de.ibm.com 2015-09-17T16:30:35+00:00 7681df456f97f21fb70f184702696d644e273d73 A couple of compat wrapper functions are simply trampolines to the real system call. This happened because the compat wrapper defines will only sign and zero extend system call parameters which are of different size on s390/s390x (longs and pointers). All other parameters will be correctly sign and zero extended by the normal system call wrappers.
