This fixes a bug where ``dumpon <device>'' will configure the dump
device at a random offset on the disk if <device> isn't a valid
partition.

(1) Use namei() and devfs to discover devices rather than a hard-coded
MAKEDEV implementation. Once rootfs is in place, this will allow
Vinum to be used for the root file system partition.
(2) Pass FREAD to device opens so that GEOM will return sector size
rather than an error on attempts to read label data.
(3) Avoid clobbering return values from close_drive() and masking this
failure, resulting in a later divide by zero due to not having
updated the Vinum-cached sector size.
(4) Ignore failures from DIOCWLABEL as that appears not to be required
in the GEOM environment.
We've done testing in simple Vinum environments, but those with more
complex environments might want to give this a spin in DP2 and make
sure everything is up to speed.

This allocate the best IRQ to boot-disable devices (have IRQ 0).
Allocated IRQ will be used for PCI interrupt routing when ACPI is

people can easily notice the strange behavior if it happened.
a consistent interface to h/w and s/w crypto algorithms for use by the
kernel and (for h/w at least) by user-mode apps. Access for user-level
code is through a /dev/crypto device that'll eventually be used by openssl
to (potentially) accelerate many applications. Coming soon is an IPsec
that makes use of this service to accelerate ESP, AH, and IPCOMP protocols.
Included here is the "core" crypto support, /dev/crypto driver, various
crypto algorithms that are not already present in the KAME crypto area,
and support routines used by crypto device drivers.

This will be removed when new versions of syscalls sigreturn()
and sigaction() are added (mini is working on this but is in
the middle of a move).
This should fix the problem of cvsupd dying.
SCSI disks are too square pegs for the round holes in both of these.
And since atapi-cd has clearly shown that there are better acccess
models for CD media than trying to pretend to be a classical disk,
we stop the masquerade rather than patch up the costume.
But do implement the DIOCGMEDIASIZE and DIOCGSECTORSIZE so it will
be possible to manually attach to GEOM, should some the need arise.
Ideally, this driver should do media-detection and call make_dev()
when a CD is inserted and destroy_dev() when it is removed, this
would allow our future devd(8) to automount etc etc but coding that
takes SCSI-clue beyond anything I posses.

preallocate a bunch of threads (and hence kstacks) while contigmalloc()
still works, and never free them back to the general memory pool. After
the system has been running for a while, contigmalloc() eventually fails
at a critical momemt and panics the system.
