Al Viro 6bcdd2972b powerpc/ptrace: Use copy_{from, to}_user() rather than open-coding 
In PPC_PTRACE_GETHWDBGINFO and PPC_PTRACE_SETHWDEBUG we do an
access_ok() check and then __copy_{from,to}_user().

Instead we should just use copy_{from,to}_user() which does all that
for us and is less error prone.
