[S390] Convert sys_clone to function with parameters.
Use function parameters instead of accessing the pt_regs structure to get the parameters. Also merge the 31 and 64 bit versions since they are identical. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
