512) bytes; ffs is inextricably tied to using b_blkno and disklabel
always uses sectorsize units.
Thus use DEV_BSIZE units for all fields describing ffs filesystems
and convert to/from sectors where required. This enables the creation
and use of ffs filesystems on non-512 byte sectorsize devices.
This diff allows i386 and sgi (the two test platforms) to find
disklabels that are not on a sectorsize boundary. Same change to
further archs coming.
This is a no-op on 512-byte sectorsize devices.
This work triggered by jsing@'s need to create ffs filesystems on
sgi cdroms so we can create cdrom install media for sgi.

Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.

file copies to nfsv2 causes the system to eventually peg the console.
On the console ^T indicates that the load is increasing rapidly, ddb
indicates many calls to getbuf, there is some very slow nfs traffic
making none (or extremely slow) progress. Eventually some machines
seize up entirely.

biowait() reads that do *not* come from the buffer cache - we use the
B_RAW flag to identify these at art's suggestion - since it makes sense
and the flag was not being used. this just flags all these buffers with
B_RAW - biodone already ignores returned buffers marked B_RAW.

contiguous 64MB DIMMs in a single 128MB one) are not reported as memory at
offset zero, but actually as duplicates of the first entry (which always
matches real memory).
If the DIMMs are set up in decreasing sizes, as recommanded by SGI, the
first entry will be configured at offset zero, so the existing code would
run fine.
If, however, you order your DIMMs in a different order, the first entry
might not be at offset zero, so the kernel will mess up its memory
information, which will cause random effects from simply misreported memory
sizes, to the inability to boot.
Fix this by strengthening the check for an empty bank.
Problem reported by Jason Bergstrom (bergie, bergie dot net), analysis
and fix by me.

If it exists assume that the boot loader has provided a pointer to the end
of the symbol table. If it does not exist fall back to the previous
behaviour and expect that pointers to the symbol table have been provided
directly after the kernel.

Specify the serial configuration from within the MD code, rather than
passing things via macros. This will allow other platforms to more readily
change the serial console configuration.

HUB driver (for IP27) is a stub, and interrupt support is a shoot in the dark
and will need some serious debugging until it is sane, but I want to reduce
the weight of these diffs first.
