It is possible for a TCP callout to be removed from the timing wheel,
but have a network interrupt arrive and deactivate the timeout before
the callout routine runs. Check for this case in the callout routine;
it should only run if the callout is active and not on the wheel.
- Add a new process flag P_NOLOAD that marks a process that should be
ignored during load average calcuations.
- Set this flag for the idle processes and the softinterrupt process.

Also coerce diff(1) into working the other way (from no-\n to \n).
Taking out the evil warning fixed it one way, but didn't make the
other way any better, so replace it with printing a single \n.
The boot-conf and boot code had various bugs, and some of it was big,
ugly, unwieldy, and, sometimes, plain incorrect. I'm just about
completely replaced these ugly parts with something much more manageable.
Minor changes were made to the well-factorized parts of it, to accomodate
the new code.
Of note:
* make sure boot-conf has the exact same behavior wrt boot order
as start.
* Correct both boot and boot-conf so they'll work correctly when
compiled in, as they both had some bugs, minor and major.
* Remove all the crud from loader.4th back into support.4th, for
the first time since boot-conf was first improved. Hurray!
I'm fairly satisfied with the code at this time. Time to see about those
man pages...
pkg_version(1) will now distinguish between the different cases where
the exact relationship between an installed package and its
corresponding entry in the index file can't be determined.
Check to see if we actually have an interrupt descriptor and an interrupt
thread for each interrupt that comes in. If we don't, log the event and
return immediately for a hardware interrupt. For a softinterrupt, panic
instead.
Add Timer device driver for power management events.
The code for suspend/resume is derived from APM device driver.
Some people suggested the original code is somewhat buggy, but I'd
like to just move it from apm.c without any major changes for the
initial version. This code should be refined later.
To use pmtimer to adjust time at resume time, add
device pmtimer
in your kernel config file, and add
hint.pmtimer.0.at="isa"
in your device.hints
Allow tftpd to run as a specified user, not just `nobody'.
Update documentation to reflect new option. Also fix documentation
style and add missing references.
Make the [u]random device's permissions match those in the matching
make_dev() call.
At the moment, it is an error for anyone but root to write to this
device (EPERM), and the permissions don't suggest that. Soon, however,
anyone will be able to write here, but only root will cause an implicit
reseed.

Another overhaul of the periodic stuff.
All periodic sub-scripts <larf> now have their return codes interpreted
by periodic(8). Output may be masked based on variable values in
periodic.conf.
It's also now possible to email periodic output to arbitrary addresses,
or to send it to a log file, examples of which can be found in
newsyslog.conf.
The upshot of it all should be no discernable changes to the default
behaviour of periodic(8).
There is no reason to clobber ${DESTDIR}/usr/include/{isofs,ufs,dev}
in SHARED=copies case since all symbolic links previously created by
SHARED=symlinks install have already been removed to that point.
- Newbus'ify and bus_space'ify.
- Separate bus dependent part and independent part.
- Moved source files to sys/dev/fe (repo copied).
- Fixed some comments by chi@bd.mbn.or.jp (Chiharu Shibata)
Tested by: bsd-nomads@clave.gr.jp and
FreeBSD98-testers@jp.freebsd.org
- Remove the inthand2_t type and use the equivalent driver_intr_t type from
newbus for referencing device interrupt handlers.
- Move the 'struct intrec' type which describes interrupt sources into
sys/interrupt.h instead of making it just be a x86 structure.
- Don't create 'ithd' and 'intrec' typedefs, instead, just use 'struct ithd'
and 'struct intrec'
- Move the code to translate new-bus interrupt flags into an interrupt thread
priority out of the x86 nexus code and into a MI ithread_priority()
function in sys/kern/kern_intr.c.
- Remove now-uneeded x86-specific headers from sys/dev/ata/ata-all.c and
sys/pci/pci_compat.c.
- Fix spinlock exiting to handle recursion properly and only enable
interrupts at the proper time.
- Remove an uneeded test and just always set the MTX_RECURSE bit when
recursing on a sleep lock.
- Fix spinlock exits to properly handle the recursion count and only
re-enable interrupts when actually releasing the lock.
- Bring across some fixes to propagate_priority from the x86 code.
(It still doesn't work properly, however.)
- Use the SMTX state when putting a process that blocks on a mutex to sleep.
- Use mi_switch instead of cpu_switch so that accounting works properly as
well as other things.
- Bring across DDB protection of the spinlock timeout panic which is useful
in a multiple CPU system when 1 CPU enters the debugger holding the
sched_lock so that the other CPU doesn't panic as well resulting in all
sorts of fun things.
- Bring across various other small changes in format strings and comments
to sync up with the x86 code.
Import the global sched_lock variable instead of using a private copy. This
fixes a problem where cpu_switch() wasn't properly saving and restoring
the recursion count for sched_lock.
Be more careful about cleaning up the stack after function calls early
in the boot. The cleanup must be done in one of the few ways that
db_numargs() understands, so that early backtraces in ddb don't underrun
the stack. The underruns caused reboots a few years ago when there
was an unmapped page above the stack (trapping to abort the command
doesn't work early).
Fixed hang on booting with -d. mtx_enter() was called on an uninitialized
lock. The quick fix in trap.c was not quite the version tested and had no
effect; back it out.

Unlock current directory when calling VFS_ROOT() because underlying
filesystem may hold the lock. Otherwise unavoidable deadlock will occur.
This shouldn't have any side effects as long as we hold vfs lock.
Add ID for 3C1. It is a etherlink iii in a CompactFlash form factor.
It doesn't seem to work, but at least is identified correctly. Minor
tree housekeeping on my part.
A new driver for PCI:SCSI RAID controllers based on the Adaptec FSA
design. This includes integrated Dell RAID controllers, the Dell
PERC 2/QC and the HP NetRAID-4M.
* Redo the cmpset inlines to use one less register. This incidentally
fixes a serious problem with the previous version where an input could
have been placed in the same register as an output which would stop
the inline from working properly.
* Redo atomic_{set,clear,add,subtract}_{32,64} as inlines since the code
sequence is shorter than the call sequence to the code in atomic.s.
I will remove the functions from atomic.s after a grace period to allow
people to rebuild kernel modules.
