One more patch for Alpha console issues...

[Peter Grehan]

 > Any further thoughts?

  The problem is that make_dev() calls devlock(), which requires
curthread to be valid to take out a mutex.

  The fix is to put the hand-crafting of proc0, thread0 and pcpu
data and mutex_init to be *before* the call to cninit(). This
is why i386 works.

  I had the same problem on PPC, and fortunately had the psim simulator
to work out what was going on.

later,

Peter.
