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.

aa05f00e7e don't map syscall pages into process space 
Request pages, response pages, and a doorbell page are mapped into
process space to enable user processes to delegate system calls
directly to mcctrl/mcexec.

This commit removes these mappings for the following reasons.
- These mappings cause a memory leak in current fork() implementation.
- These mappings are not used.
- These mappings do not function properly.
  And the fix which corrects function of these mappings is not easy.
