These drivers are now in dev/vme.
...
The `ie' driver has been split in a VME and OBIO front-end. The latter
lives on in this directory as `if_ie_obio.c'

After writing to the IOMMU flush registers, read something back from
...
IOMMU control space to a flush register to drain internal write buffers (?).
This avoids utter lossage on some machines (SS4s & SS5s) where our caller
would see some of its local (`%lx') registers trashed. This is probably
caused by a silicon bug allowing interference on internal data paths..

add new version of non contiguous memory code, written by chuck cranor,
...
called "MACHINE_NEW_NONCONGIG". this is required for UVM, the new VM
system (also written by chuck) that is coming soon. adds new functions:
vm_page_physload() -- tell the VM system about an area of memory.
vm_physseg_find() -- returns index in vm_physmem array that this
address is in.
and several new versions of old functions/macros defined in vm_page.h.
this is the sparc portion.

fix mixer code that was clearly untested:
...
- allow get/set of enums SUNAUDIO_SOURCE and SUNAUDIO_OUTPUT rather
than returning EINVAL
- add missing SUNAUDIO_MONITOR_CLASS case in query_devinfo
- convert SUNAUDIO_MONITOR case from a MIXER_CLASS to a MIXER_VALUE
like it is supposed to be
- the labels for outputs/record class were swapped: fix it

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).
