s390 needs to change some parts of arch/um/kernel/ptrace.c. Thus, the code regarding PEEKUSER and POKEUSER are shifted to arch/um/sys-<subarch>/ptrace.c. Also s390 debug registers need to be updated, when singlestepping is switched on / off. Thus, setting/resetting of singlestepping is centralized in the new function set_singlestep(), which also inserts the macro SUBARCH_SET_SINGLESTEP(mode), if defined. Finally, s390 has the "ieee_instruction_pointer" in its registers, which also is allowed to be read via ptrace( PTRACE_PEEKUSER, getpid(), PT_IEEE_IP, 0); To implement this feature, sys_ptrace inserts the macro SUBARCH_PTRACE_SPECIAL, if defined.
