changes for example:
(From Craig Leres):
tip to a rocketport line
run "/etc/rc.d/devfs restart"
exit tip
(wait for the system to reboot)
Thanks to Robert Watson for poking me to fix this.

- Instead of bus_space_{read,write}*(rman_get_bustag(), rman_get_bushandle())
use bus_{read,write}*() for efficiency.

- Use BAR2 rather than BAR0 for the Rocketport UPCI 8O card. I suspect
that other UPCI cards might need to use BAR2 as well.

future:
rename ttyopen() -> tty_open() and ttyclose() -> tty_close().
We need the ttyopen() and ttyclose() for the new generic cdevsw
functions for tty devices in order to have consistent naming.
least the pci device unloadable
- Use ttymalloc() rather than a plain malloc to allocate the
rp->rp_tty ttys. This is now required due to the recent locking
changes to ttys and prevents a panic due to locking an unitialized
t_mtx.
- Allow the pci driver to be unloaded. This involved moving
the call rp_releaseresource() to the end of rp_pcireleaseresource(),
since rp_pcireleaseresource() uses ctlp->dev, which is freed
by rp_releaseresource().
- Allow the generic part of the driver to be unattached by providing
a hook to cancel timeouts.

Use this function from all the relevant drivers.
I belive no drivers finger linesw[] directly anymore, paving the way for
locking and refcounting.
Introduce d_version field in struct cdevsw, this must always be
initialized to D_VERSION.
Flip sense of D_NOGIANT flag to D_NEEDGIANT, this involves removing
four D_NOGIANT flags and adding 145 D_NEEDGIANT flags.
Add missing D_TTY flags to various drivers.
Complete asserts that dev_t's passed to ttyread(), ttywrite(),
ttypoll() and ttykqwrite() have (d_flags & D_TTY) and a struct tty
pointer.
Make ttyread(), ttywrite(), ttypoll() and ttykqwrite() the default
cdevsw methods for D_TTY drivers and remove the explicit initializations
in various drivers cdevsw structures.
Free approx 86 major numbers with a mostly automatically generated patch.
A number of strategic drivers have been left behind by caution, and a few
because they still (ab)use their major number.
branches:
Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.
This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

general cleanup of the API. The entire API now consists of two functions
similar to the pre-KSE API. The suser() function takes a thread pointer
as its only argument. The td_ucred member of this thread must be valid
so the only valid thread pointers are curthread and a few kernel threads
such as thread0. The suser_cred() function takes a pointer to a struct
ucred as its first argument and an integer flag as its second argument.
The flag is currently only used for the PRISON_ROOT flag.

least the following programs in the src tree:

make the kernel aware that there are smaller units of scheduling than the

This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Note:
- the old driver still lives in src/sys/i386/isa, so that you can
revert to it if something goes wrong.
- The module does not detach very well. Attaching works fine.
