numbers and handle types in rational way. This will better protect from
(unwittingly) dealing with stale handles/commands.
Fix the watchdog timeout code to better protect itself from mistakes.
If we run an abort on a putatively timed out command, the command
may in fact get completed, so check to make sure the command we're
timing it out is still around. If the abort succeeds, btw, the command
should get returned via a different path.
Add Power Up In Stand-by feature support. Device with PUIS enabled
require explicit command to do initial spin-up. Mark that command
with CAM_HIGH_POWER flag, to allow CAM manage staggered spin-up.
Make CAM to stop all attached devices on system shutdown.
It allows devices to park heads, reducing stress on power loss.
Add `kern.cam.power_down` tunable and sysctl to controll it.
successfully. Continue to do this before the empty path check so that the
ENOENT returned in that case gets an empty string token in the BSM record.

these cases the loopback route is not installed for the local

TNT5004 IC. This involved a major rewrite of a number of things, as
this chip no longer supports the NAT7210 legacy mode but requires the
host to use the (more modern) FIFO mode.
In theory, this also ought to work on the older TNT4882C chip. I'll
probably add this as optional support (perhaps by a device.hints flag)
later on. By now, FIFO mode is *only* activates iff a TNT5004 chip
has been detected (where the old code didn't work at all), while
everything else is supposed to use the old code.

1. checking whether there's a link before initializing devices
on the bus. When there's no link any access onto the bus
will wedge the CPU.
2. synthesizing the class & subclass so that the host controller
appears as a standard PCI bridge, rather than a PowerPC CPU.
PCI Express, rather than a bit-field (boolean). Saving the capability
pointer this way makes access to capability-specific configuration
registers easy and efficient.
For our compiler the two constructs are completely equivalent, but
some compilers (including MSC and tcc) use the base type for alignment,
which in the cases touched here result in aligning the bitfields
to 32 bit instead of the 8 bit that is meant here.
Note that almost all other headers where small bitfields
are used have u_int8_t instead of u_int.

- Remove the BUS_HANDLE_MIN checking in the __BUS_DEBUG_ACCESS macro;
for UPA it should have fulfilled its purpose by now and Fireplane-
and JBus-based machines are way to messy in organization to implement
something equivalent.
- Fix a bunch of style(9) bugs.
- Const'ify the bus_stream_asi and bus_type_asi arrays.
- Replace hard-coded functions names missed in bus_machdep.c with __func__.
- Break some long lines.
for negative name cache entries in a manner analogous to
r202767 for the regular NFS client. Also, make the code in
nfs_lookup() compatible with that of the regular client
and replace the sysctl variable that enabled negative name
caching with the mount point option.

While there, perform some clean-up fixes. Update some stale comments on
struct cdev * instead of dev_t and devfs_random(). Also add some missing
whitespace.

This may not be entirely correct either, but the existing check is
bogus. I have both a C3 and a C7 that fail this check, but work fine.
