Use the generic ptrace_resume code for PTRACE_SYSCALL, PTRACE_CONT, PTRACE_KILL and PTRACE_SINGLESTEP. This implies defining arch_has_single_step in <asm/ptrace.h> and implementing the user_enable_single_step and user_disable_single_step functions, which also causes the breakpoint information to be cleared on fork, which could be considered a bug fix. Also the TIF_SYSCALL_TRACE thread flag is now cleared on PTRACE_KILL which it previously wasn't, which is consistent with all architectures using the modern ptrace code. The old code only disables the breakpoints on PTRACE_KILL, while after this patch this also happens for PTRACE_CONT and PTRACE_SYSCALL which matches the behaviour of the other architetures. I think this is a bugfixes, but please double verify this is correct.
