Remove non-standard <sys/dkstat.h> header. It has not contained anything
related to disk stastics for almost 17 years, and the remaining
userland-visible defines duplicate those found in <sys/sched.h>.

Move the remaining _KERNEL defines to <sys/tty.h> where they belong, and
update all users to cope with this.

Currently pdc_scanbus() scans in reverse, which results in physical CPU0
attaching as cpu1 and physical CPU1 attaching as cpu0. Split the device
scan into two parts - the first pass scans forward and attaches memory
and CPUs, whilst the second pass scans in reverse attaching the
remaining devices, thus preserving current semantics.

Found the hard way whilst trying to spin up the secondary CPU on my j6750.

Print bootpath in the canonical place.

Subsequent address ranges start at index 1, not index 0.

Infrastructure to allow root on wd0.

some architectures called setroot() from cpu_configure(), *way* before some
subsystems were enabled. others used a *md_diskconf -> diskconf() method to
make sure init_main could "do late setroot".

rename scsibus_attach_args to scsi_attach_args. this can help avoid

for attaching scsi devices to scsibus.

Remove unused sw_nblks field of struct swdevt. Then, remove swapconf()
which duplicates work done by uvm_swap_init().

Use list and queue macros where applicable to make the code easier to read;
no functional change.

scan cpu bus manually for some machines do not support that in prom

print layers in hex
