different meanings for read and write.
This fixes 48kHz playback to SPDIF.
- Fix the problem where the SPDIF output voltage setting (0.5V, 5V)
was swapped. The default value is changed from 0.5V to 5V, which
correctly selects 5V (so the default physical behavior is unchanged).
Should fix PRs kern/16047 and kern/16817
(but not tested since I don't have other SPDIF hardware to test with).

- tweak some attach messages
- establish interrupt after all dma resouces are successfully allocated
- wrap an assertion with #ifdef DIAGNOSTIC
- assume NCRCFG2_FE bit is always enabled
- call bus_dmamap_sync for mdldmap at POSTWRITE for consistency
- pass proper dmamapsize for mdldmap
Not tested on 795[56], but compiles and matches FreeBSD-tested diffs.

- factor out disksubr.c between sun3, sparc and sparc64. Keep the sun3
groveling code to find a NetBSD disklabel in the first sector (so that it
can find a label at the old sun3 LABELOFFSET) as a fallback is not
label at LABELOFFSET, or sun label is present.
- Fix the sun3 LABELOFFSET (was 64, but the kernel wrote the NetBSD label at
128)
- Make next68k disksubr.c always write a next-compatible disklabel.
- remove #ifdef __sparc__ hack from disklabel(8), and change it to issue
a DIOCWDINFO after writing the disklabel to the raw partition in the
-r/-I case (so that the kernel can convert the label if needed).
This reloads the entire EEPROM, not just the MAC address, which can
cause problems for the host PCI bus under certain circumstances. The
chip already loads the EEPROM at powerup/reset anyway.
XXX: This probably applies to the other Rhine variants too, but I don't
have a data sheet to confirm this behaviour.
copyin() or copyout().
uvm_useracc() tells us whether the mapping permissions allow access to
the desired part of an address space, and many callers assume that
this is the same as knowing whether an attempt to access that part of
the address space will succeed. however, access to user space can
fail for reasons other than insufficient permission, most notably that
paging in any non-resident data can fail due to i/o errors. most of
the callers of uvm_useracc() make the above incorrect assumption. the
rest are all misguided optimizations, which optimize for the case
where an operation will fail. we'd rather optimize for operations
succeeding, in which case we should just attempt the access and handle
failures due to insufficient permissions the same way we handle i/o
errors. since there appear to be no good uses of uvm_useracc(), we'll
just remove it.
- process pending queries in EcUnlock() to close a race window.
now there's no need to do polling for EcQuery().
- reorder inline functions and other prototypes so that
the formers can get needed prototypes.
- add missing prototypes.
* erratum: disable the nocrc RX bit, as it may cause problems on the 570{1-4}.
adjust the length of the incoming packet accordingly to trim it.
* the 5704 has a smaller MBUF_POOL, so set a smaller value
Local change:
* Pass the autoneg force flag to mii_attach. Some PHYs need to be kicked
out of their falsely autoneged 10baseT state with this.
