- Replace vtophys() with MIPS_KSEG0_TO_PHYS() to convert a page table
page's virtual address to physical. We can safely do this because
page table pages are allocated out of KSEG0.
- Add an assertion to verify that when a page table page is freed it
contains all zeroes. We can now use it after allocation without
zeroing it.
DDB so that all the fields line up.
- Print out the tid of the per-CPU idlethread instead of the pid since
the idle process is now shared across all idle threads.

- Read the number of hard drive devices from the BIOS instead of hardcoding

where running ofwdump could cause hangs by forcing all secondary CPUs
into a busy wait with interrupts off during the call.
Following section 8.4 of the Open Firmware PowerPC processor binding,
the firmware is free to overwrite the system interrupt handlers during
OF calls, restoring the OS handlers on exit. On single CPU systems, this
process is invisible to the operating system. On multiple CPU systems,
taking any exception on a secondary CPU while an OF call is in progress
ends with that exception vectored into OF, resulting in a slow movement
of the entire system into firmware context and a machine hang.

priv->ctlsock is checked at the top of the function but without any
lock held, which means the control socket state may certainly change.
Add a similar protection to ngs_shutdown() even if a race is unlikely
to be experienced there.

loader(8)
In r193192 loader(8) has grown an ability to pass root mount options
from fstab via vfs.root.mountfrom.options. Unfortunately, some options
that can be present in fstab are for userland only and lead to root
mounting failure when seen by kernel.
Rather than teaching loader about FFS-specific options that should be
filtered out, ffs_mount recognizes those options as valid, but ignores
and deletes[1] them.
