8abe76d2f0 Add offset and length parameters to bus_dmamap_sync(), used for specifiying 
partial syncs of a DMA mapping.

99cc8482d1 Change the last argument of bus_dmamap_sync() from bus_dmasync_op_t to int, 
and allow more than one synchronization operation to be specified in
a single call.  Dissallow mixing of PRE and POST operations.

8a5023e38c 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..

c599e7d439 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.

d76941843e 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
