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

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.
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).

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.
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.
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).
Cleaned up some nearby code.
