3d83dee874 Use a global variable to hold the current speed of the internal serial port. 
This will be used by certain SCSI drivers to limit the length of DMA transfers
when the serial port is running at higher speeds.  GVP and Phase5 DMA
interfers significantly with CPU execution, and significantly increases
receive buffer overruns (silo overflow).  Reducing the DMA transfer length
can reduce the overruns.

f596be4ec4 Fix the problem described in PR port-i386/4177: scroll lock could cause 
tsleep() to be called from an interrupt handler.
The semantics of the scroll-lock key is changed now: it issues a ^S or
^Q, depending on the current state. (It should probably issue
tp->t_cc[VSTOP] or tp->t_cc[VSTART] instead, but this would require more
serious structural changes because there is not always a tty context
present.)
The "scroll lock" LED is now controlled by pcstart()/pcstop(), so it
will show the real state even if the start/stop characters are remapped
or the normal ^S/^Q are used.

NOTE: due to hardware requirement of the AGA chipset, the framebuffer width
has to be a multiple of 64 bits.  An 800x600 display will use a memory width
of 832 bits, which the current X server can't handle.  To get a usable
display, the width needs to be 832 or 768.

in the VM system putting pages back on the free list which are still
mapped.   This may cause a deadlock later trying to enter pages into

d1fbc82e28 From page 6-9 of "Alpha AXP Architecture Reference Manual, Second Edition": 
An IMB intruction must be executed after software or I/O devices
	write into the instruction stream or modify the instruction
	stream virtual address mapping, and before the new value is
	fetched as an instruction.

We were missing calls to IMB after mappings were changed, which caused
systems with large I-caches (e.g. my AlphaStation 500) to fail miserably
when mapping in new pages of program text, or when context switching
(I couldn't even get the shell from init!).

998d79d26a Add support for DDB (in-kernel debugger) to NetBSD/alpha, based on 
such code for Mach 3's Alpha port.  Initially reworked for NetBSD/alpha
by Chris Demetriou, and then heavily hacked on by me.  Works, but is still
a little rough around the edges.  Known problems:

- Error recovery could be improved a bit.
- Back traces don't work.
- Single-stepping can be flaky, at times.  (Alpha doesn't have hardware
  support for single-stepping, and I'm not entirely convinced the
  MI DDB software-emulated single-stepping logic is 100% correct.)
- Logic for when to drop into DDB needs some improvement.
