9ba40dc0ff schedule(): hold runq lock for the entire duration of context switching 
releasing the runq lock after loading page tables but before the actual
context switch can leave execution in an inconsistent if the current
process is descheduled from an IRQ between these two steps.
this patch holds the runq lock with IRQs disabled and makes the context
switch a single atomic operation.

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.
