Fixes for the 31 bit compatability layer:
 * add compat function for jiffies_to_timeval
 * convert parameters of clone system call
 * incorporate changes from setup_arg_pages to setup_arg_pages32
 * incorporate changes from do_execve to do_execve32
 * take care of nanosecond field in struct timespec
 * remove functions of old module system calls
 * add TIF_31BIT thread flag and replace S390_FLAG_31BIT with it
 * add arch_get_unmapped_area
 * add wrapper for sys_set_tid_address

s390 arch changes/bug fixes:
 * add sys_fadvise64 system call
 * add initialization of init_sighand
 * add support for clone option CLONE_SETTLS
 * make use of ptrace_notify
 * sig -> sighand rename
 * move ptrace_signal_deliver to the correct place
 * make eieio a memory barrier
 * fix race condition on cpu_vm_mask in __flush_tlb_mm
 * add missing KM_SOFTIRQ0, KM_SOFTIRQ1 in asm-s390x/kmap_types.h
 * add inline assmelby for _raw_write_trylock

Add additional parameter for do_fork.

Rewrite s390 ptrace code in a more readable and less buggy way. As a part of
this, all psw related definitions are moved into ptrace.h from a number of
different locations.

Cleanup load/store of fpu register on s390.

Remove bogus sanity checks and code cleanup.

s390 arch file changes for 2.5.39.

This first patch contains the changes to arch/{s390,s390x}

This changes do_fork() to return the task struct, rather than the PID.

Also changes CLONE_PID ("if my pid is 0, copy it") to CLONE_IDLETASK
("set child's pid to zero"), and disallows access to the flag from user
mode.
