a90ace971a Workaround for the "xanim volume setting problem": 
We play mono samples on all 4 channels.
However, we get the volume settings for mono samples as a symmetic two-channel
setting... the other two channels used to stay at max volume...
I believe that something else is wrong here, but dont want to change MI
code (which in turn influences a couple of MD driver) thus late in the release
cycle.

46c5ad921d Add a workaround for buggy i486 PCI chipsets that have trouble with 
memory-mapped device access (manifested by an apparent wedging of the
PCI bus):
- If cpu_class == CPUCLASS_486, disable memory-mapped PCI device access,
  leaving only i/o-mapped access enabled.
- Provide a patchable kernel variable (i486_pci_mem_enabled) and a kernel
  option (I486_PCI_MEM_ENABLED) to re-enable it.

de106f6489 1. Implement a trick from Chris Torek: if an unhandled interrupt occurs 
during auto-configuration (`cold'), raise interrupt level to splhigh
   and return, instead of reporting a stray interrupt.

2. In cpu_switch(), start running a newly selected proces at splclock()
   instead of the saved IPL, allowing high-priority interrupts in
   ctx_alloc() which can take many cycles to install a new context
   (especially on the two-level sun4c MMU).

1adbb93466 * Disable parity checking on all devices until we find a better way to 
deal with cheap CD-ROMs and other devices that do not appear to have
  any way to enable parity generation.  In the future, it might be nice
  to have this configurable on a per-device basis with back-to-back
  parity errors automatically disabling parity for the device.  That
  would require some MI changes.
* Handle unaligned and odd-length transfers.
  This could probably be handled better in the future.

44c123573b Define PC_ADVANCE() to advance the PC around the break instruction only

the software single step in DDB not recognizing the temporary breakpoint
