Looks good to me, except you also want to nix PTRACE_KILL from your switch so the generic code handles it. Same goes for {PEEK,POKE}{DATA,TEXT} too. Also note that you have to define a PTRACE_SINGLEBLOCK value in asm/ptrace.h (new request code in your ptrace syscall ABI) to make user_enable_block_step() get used by anything.
