- Move the command timeout check from a separate repeating timeout to the
kthread since the kthread is already running periodically.
- Move printing the hardware print buffer to the kthread.
- Properly shut down the kernel thread on detach.
- Detach the child array devices on detach.
- Don't issue a controller halt command on detach. Doing so requires a PCI
reset to wake the controller back up. The driver can now be unloaded as
long as CAM support is not enabled.
similar patch has been in 4.x for a while, but is more hacky there.)
For this to work, vinum has to be loaded early (e. g. from
boot/loader), for obvious reasons. If the kernel env variable
(aka. loader variable) "vinum.autostart" is set, vinum then asks the
sysctl kern.disks for all available disks in the system, and scans
them for possible vinum headers.
For statically compiled kernels, this behaviour can be obtained even
without boot/loader by using "options VINUM_AUTOSTART" (though this is
not the recommended way).
Alternatively, the 4.x way to specify "vinum.drives" is also supported.
No further hacks (like the 4.x "vinum.root" variable) are needed,
since in 5.x, mountroot() asks back at the drivers to have them
resolve the name of the root FS into a dev_t (using the dev_clone
eventhandler).
(The MFC reminder below is for a partial MFC for vinum.autostart, the
rest is already there in 4.x.)

we have the rc4 code already in the kernel (via wlan stuff or awi).
Add a dependency on the rc4 module so if it doesn't exist then load it.

NOTE: This undoes some changes I'd made to prefix the processor name defines
with PVR_. This was due to my original decision to use MPC750 as a cpu name.
With this changed, the PVR_ change is no longer required.
* Give back one line of ws when showing a diff.
This was requested by several.
* Un-quote DIFF_FLAG, and add DIFF_OPTIONS. This will allow the user to
do more creative things in a mergemaster rc file. Un-quoting is necessary
in order to handle things like CVS Id tags that look like shell variables.
* Simplify terminal width determination.
Suggestions related to ignoring the CVS Id's were taken from several, with
dillon and gad providing particularly helpful feedback.
Remove all the stuff that does not relate to the TSC.
Change the calibration to use DELAY(1000000) rather than trying to check
it against the CMOS RTC, this drastically increases precision:
Using 25 samples on a Athlon 700MHz UP machine I find:
stddev min max average
CMOS 22200 Hz -74980 Hz 34301 Hz 704928721 Hz
DELAY 1805 Hz -1984 Hz 2678 Hz 704937583 Hz
(The difference between the two averages is not statistically significant.)
expressed in PPM of the frequency:
stddev min max
CMOS 31.49 PPM -106.37 PPM 48.66 PPM
DELAY 2.56 PPM 2.81 PPM 3.80 PPM
This code will not be used until a followup commit to sys/isa/clock.c
and sys/pc98/pc98/clock.c which will only happen after some field testing.
