member of 'struct scsi_xfer' has always been pointed at the 'struct scsi_generic
cmdstore' member of the same instance. So nuke 'cmdstore' and remove the '*'
from cmd. Take the address of cmd as required by the various casts.
No intentional functional change.

In sparc64 autoconf access 'luns' via sb_luns and 'adapter_buswidth'
via sb_adapter_buswidth.
Removes last post-config uses of the copies of bus related

the width of the bus it is providing, it should rely on info in its
softc. i.e. not on info in the prototype scsi_link that is passed out
for other bits of the kernel to fiddle with.
Most drivers already do this. Make it so for the laggards iha(4) and
siop(4). Actually use the existing softc value in wd33c93.c.
No intentional functional change.

time_second(9) and time_uptime(9) are widely used in the kernel to
quickly get the system UTC or system uptime as a time_t. However,
time_t is 64-bit everywhere, so it is not generally safe to use them
on 32-bit platforms: you have a split-read problem if your hardware
cannot perform atomic 64-bit reads.
This patch replaces time_second(9) with gettime(9), a safer successor
interface, throughout the kernel. Similarly, time_uptime(9) is replaced
with getuptime(9).
There is a performance cost on 32-bit platforms in exchange for
eliminating the split-read problem: instead of two register reads you
now have a lockless read loop to pull the values from the timehands.
This is really not *too* bad in the grand scheme of things, but
compared to what we were doing before it is several times slower.
There is no performance cost on 64-bit (__LP64__) platforms.
With input from visa@, dlg@, and tedu@.
Several bugs squashed by visa@.

Use a monotonic clock for timestamping LUNs to avoid problems when the
UTC clock jumps.

Using a name with the 'db_' prefix makes it invisible from the dynamic

the ioff argument to pool_init() is unused and has been for many
years, so this replaces it with an ipl argument. because the ipl
will be set on init we no longer need pool_setipl.
most of these changes have been done with coccinelle using the spatch
below. cocci sucks at formatting code though, so i fixed that by hand.
the manpage and subr_pool.c bits i did myself.

(we need to make them signed to spot controller overruns), and fix format
strings accordingly.
While there, make sure every runtime printf is prefixed by either the complete
target information, if available, or at least the driver name with the
proper instance number - supported systems with > 1 wdsc are quite common.

the nonexistent LUNs of the Insite Floptical probe (as non-existing)
correctly.
Step two of Floptical support, now if only the loading mechanism would unjam
I could try some real I/O with it...

if their size is not exactly six bytes, as the chip can't cope with this
situation.
Another situation all 33C93 do not cope with very well, is sending stop
commands to targets (such as all sd(4) devices when halting with poweroff) -
it takes a very long time to recover once all targets on the bus have been
powered down, so we need to raise timeouts to unholy values (one test case has
required more than 20 seconds to recover). Not surprising, as this command
is not documented as supported in the chip documentation.

(IP20, IP22, IP24) in 64-bit mode, adapated from NetBSD. Currently limited
to headless operation, input and video drivers will get ported soon.
Should work on all R4000, R4440 and R5000 based systems. L2 cache on R5000SC
Indy not supported yet (coming soon), R4600 not supported yet either (coming
soon as well).
Tested to boot multiuser on: Indigo2 R4000SC, Indy R4000PC, Indy R4000SC,
Indy R5000SC, Indigo2 R4400SC. There are still glitches in the Ethernet driver
which are being looked at.
Expansion support is limited to the GIO E++ board; GIO boards with PCI-GIO
bridges not ported yet due to the lack of hardware, and this kind of driver
does not port blindly.
Most of this work comes from NetBSD, polishing and integration work, as well
as putting as many ``R4x00 in 64-bit mode'' erratas as necessary, by yours
truly.
More work is coming, as well as trying to get some easy way to boot install
kernels (as older PROM can only boot ECOFF binaries, which won't do for the
kernel).
