[PATCH] s390: core s390.

From: Martin Schwidefsky <schwidefsky@de.ibm.com>

s390 core changes:
 - Fix race in do_call_softirq in regard to kernel preemption.
 - Fix typo in compat mq system call wrappers.
 - Add s390 to Kconfig for AUDITSYSCALL.
 - Redefine TASK_SIZE to TASK31_SIZE for compilation of binfmt_elf32.
 - Use correct error value for sys32_ipc when called with an invalid number.
 - New default configuration.
