fcfe2f1539 Implement a set of `atomic' (using load-locked and store-conditional) 
operations.  Initial set includes:

alpha_atomic_setbits_q()	set bits in a quad
alpha_atomic_clearbits_q()	clear bits in a quad

6e3073d769 More tty dialin/dialout changes (t_wopen). 
NB: dtop is a keyboard/mouse bus and doesn't support dialout.

a10657ae4f Set the PID before setting up the wired TLB entries for proc0. The 
mips3_HitFlushDCache() fails with a TLB miss otherwise.

9db8ae93c8 - The pmap now includes support for ASNs. We no longer need to flush 
the TLB and I-cache in the SWITCH_CONTEXT macro.
- Right after switching to proc0's newly-created context at startup time,
  flush the TLB and I-cache; this is the only place where it's not done
  automatically.
- Fix a nasty bug in a critical section of cpu_switch(); change the
  pmap_activate -> SWITCH_CONTEXT -> pmap_deactivate sequence to
  pmap_deactivate -> pmap_activate -> SWITCH_CONTEXT.  This prevents
  erroneously marking a pmap inactive if switching to a process that
  shares it's address space (and thus its pmap) with the oldproc!  Noticed
  by Chris Demetriou.

c0cc1ed476 Implement support for Address Space Numbers, greatly reducing the number 
of TLB and I-cache flushes, significantly speeding up context switches.

Once again, many thanks to Chris Demetriou and Ross Harvey for code
review and debugging assistance!

019508faee Well, I don't have a Cyclades board, but I needed the alpha kernels 
to compile. I made the changes that seemed to make sense tracking the
shift from TS_WOPEN  to tp->t_wopen- but they may be wrong. I wasn't
subscribed to tech-kern so I missed the discussion, and C. Hannum
was not particularly enlightening. Sorry if this isn't quite right.

- device attachment arguments contain bus-specific
	  address and interrupt levels.

	- devices must call back on bus map functions to get their
	  addresses and interrupt levels translated properly.

	- sun4m's obio bus is treated like an Sbus slot.

	- the sun4-style obio bus has its own attach arguments
	  and map functions.
