cppi < "$f" > "$f".cppi; mv "$f".cppi "$f"

a struct ptrace_peeksiginfo_args.

right after printing addr argument if request is one of PTRACE_GETREGS,
PTRACE_SETREGS, PTRACE_GETFPREGS, or PTRACE_SETFPREGS.
As kernel ignores addr and data arguments of PTRACE_ATTACH,
PTRACE_INTERRUPT, PTRACE_KILL, and PTRACE_LISTEN request,
we do not print them either.
* process.c (SYS_FUNC(ptrace)): After printing pid argument, return
RVAL_DECODED if request is one of PTRACE_ATTACH, PTRACE_INTERRUPT,
PTRACE_KILL, or PTRACE_LISTEN.
As kernel ignores arguments of PTRACE_TRACEME request,
we do not print them either.
* process.c (SYS_FUNC(ptrace)): If request is PTRACE_TRACEME,
return early with RVAL_DECODED.
As first argument of ptrace syscall has a long integer type, print
it using printxval64 because printxval takes unsigned int argument.

from "long" to "unsigned long", print it using printxval64 instead
of printxval.
* process.c (print_user_offset_addr): New function for printing offset
address in the tracee's USER area.
(SYS_FUNC(ptrace)): Assign syscall arguments to local variables with
appropriate types. Print pid argument as int. Use switch statement

to print address in PTRACE_PEEKUSER and PTRACE_POKEUSER requests.
