From aa33c8cbbae2eb98489a3a363099b362146a8f4c Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Tue, 27 Dec 2011 11:27:18 +0100 Subject: [S390] cleanup trap handling Move the program interruption code and the translation exception identifier to the pt_regs structure as 'int_code' and 'int_parm_long' and make the first level interrupt handler in entry[64].S store the two values. That makes it possible to drop 'prot_addr' and 'trap_no' from the thread_struct and to reduce the number of arguments to a lot of functions. Finally un-inline do_trap. Overall this saves 5812 bytes in the .text section of the 64 bit kernel.
