until UVM is no longer optional.

Back out previous change. Until the default VM system is UVM, these
...
"options" ARE required, and leaving them here doens't hurt anything in
the UVM case.

initial import of the new virtual memory system, UVM, into -current.
...
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code. i provided some help
getting swap and paging working, and other bug fixes/ideas. chuck
silvers <chuq@chuq.com> also provided some other fixes.
this is the sparc portion.
this will be KNF'd shortly. :-)

These drivers are now in dev/vme.

The `ie' driver has been split in a VME and OBIO front-end. The latter

VME device declaration changes:

- `vmes,vmel' => `vme'
- interrupt locator is the VME interrupt priority (`pri')

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..
