Also introduce a macro to be called by persistent nodes to signal their
persistence during shutdown to hide this mechanism from the node author.
Make node flags have a consistent style in naming.
Document the change.
usbdi.c rev. 1.104, author: mycroft
ugen_isoc_rintr() may recycle the xfer immediately. Therefore, we
avoid touching the xfer after calling the callback in
usb_transfer_complete(). From PR 25960.
left around after the PCI probe, acpi_video stopped attaching because while
it was an acpi child device, it really is a PCI device. Fix this by making
it a PCI child.
* Remove non-handle ivars accesses since child busses only implement
acpi_get_handle().
* Access the acpi softc directly through the devclass instead of through
the implied parent.
* Clean up a potential panic on unload by freeing the sysctl context before
storing NULL in the OID.

- `sound'
The generic sound driver, always required.
- `snd_*'
Device-dependent drivers, named after the sound module names.
Configure accordingly to your hardware.
In addition, rename the `snd_pcm' module to `sound' in order to sync
with the driver names.

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.
rev. 1.67, author: mycroft
Fix a byte order error.
rev. 1.68, author: mycroft
Adjust some silliness that was causing us to do extra work for
"frame list rollover" interrupts, which we pretty much ignore.

hints-based probe to fdc_hints_probe().
Also:
* Fix some resource leaks when attach fails.
* Remove the FDC_ATTACHED flag. It was supposed to prevent multiple
unloads but this is not necessary.
allows a bus to re-enumerate its child handles and optionally replace
them with new children, arranged to the bus's liking. (The current device
space is flat with all devices immediately under acpi0). Add comments
for each interface.
for unknown events.
A number of modules return EINVAL in this instance, and I have left
those alone for now and instead taught MOD_QUIESCE to accept this
as "didn't do anything".
when the battery is fully charged. That breaks some of the arithmetic in
calculating the remaining capacity (ends up with more than 100%).
This commit makes sure the max is 100.

Add a MOD_QUIESCE event for modules. This should return error (EBUSY)
of the module is in use.
MOD_UNLOAD should now only fail if it is impossible (as opposed to
inconvenient) to unload the module. Valid reasons are memory references
into the module which cannot be tracked down and eliminated.
When kldunloading, we abandon if MOD_UNLOAD fails, and if -force is
not given, MOD_QUIESCE failing will also prevent the unload.
For backwards compatibility, we treat EOPNOTSUPP from MOD_QUIESCE as
success.
Document that modules should return EOPNOTSUPP for unknown events.
needed so that sysresource objects are created first to reserve all regions,
then other devices can allocate from them. Otherwise, acpi_timer (the only
ACPI device with an identify routine), would allocate its resources from
the nexus, causing the later sysresource reserve to fail.

* Add an fdtype ivar. This will be the equivalent of fd->type.
* Move enabling the FIFO to the end of attach.
* Unify reset code into fdc_initial_reset().
* Add fdc_write_ivar().
* Update isa and pccard attachments accordingly.
* Set the flags unconditionally in probe since they may be overridden by
other probe routines. Both before and now, we're depending on probe
being called a final time on the winning driver so the flags we get are
the ones we intended.
* Use the bus accessor macros instead of defining our own.
* Remove duplicate assigns of fd->type.
