   PS: Should PT_READ_U  and  PT_WRITE_U be in <sys/ptrace.h>? Could somebody
   explain why or why not?

PT_READ_U and PT_WRITE_U are outdated, slow interfaces used to read
and write a process's registers from a debugger.  Implementing them
is annoying and hardly worthwhile.  Our GDB was changed some time ago
to use PT_READREGS and PT_WRITEREGS, which are simpler, faster to
use, and don't break every time the kernel is changed.
