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
this patch allows "mixerctl" to work properly on a sparc

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).

Bug fixes and cleanup from Chris Demetriou <cgd@pa.dec.com>:
...
- fix _C_LABEL so that it actually works.
- make __RENAME use _C_LABEL.
- fix __RENAME so that it expects an unquoted argument.
- fix __indr_reference and __warn_references so that they
supply their own final semicolon.
- define __warn_references to nothing if not GNU C (required
by the way it's used).
The __warn_references semicolon change has to be made
so that __warn_references can be defined into nothing.
(A ; all by itself isn't a great idea.) The __indr_reference
change was made for consistency.
