c3ade864d9 fix PTRACE_PEEKUSER, PTRACE_POKEUSER, PTRACE_GETREGS. 
support PTRACE_SETREGS.
  In struct process, add 'unsigned long *ptrace_debugreg', instead of 'struct user *userp'.
  debug registers are read/written from/to ptrace_debugreg, save/restore in schedule().
  most general registers are proc->uctx.
  fs_base is proc->thread.tlsblock_base.
  gs_base,ds,es,fs,gs and orig_rax are uncompleted.
  other members in 'struct user' are ignored, same as Linux implementation.

0942bf0ce0 make dkprintf() evaluate its parameters always 
Parameters of dkprintf() should be evaluated even if dkprintf() is
disabled.  Because this enables to find expression of parameter obsolete
and to avoid unnecessary compiler warnings such as "unused variable".
