* Serialize access to acpi_pci_link_config(), acpi_pci_find_prt(),
acpi_pci_link_route(), and acpi_pci_link_resume().
* Add lock assertions to all functions called by them.
* Serialize notifying the user in acpi_lid_notify_status_changed(). This
way multiple lid events occur in order.
* Add an initialization pass to get the lid status at boot-time. This
pass does not notify any apps but gets the initial status.
* Use the common serialization macros instead of rolling our own.
* Increase the coverage of the lock in EcSpaceHandler() to cover the entire
loop to avoid dropping the lock when reading more than one byte.
* Serialize ops in acpi_cmbat_notify_handler(), acpi_cmbat_ioctl(),
acpi_cmbat_init_battery(), and acpi_cmbat_get_battinfo().
* Get the softc directly in acpi_cmbat_get_total_battinfo() rather than
build an array of them.
* Don't queue a _BIF query after receiving a notify. Since we clear the
timespec, a _BIF query will be done in the context of the next caller.
* Add asserts to leaf functions that operate on shared data.
* Remove the bst/bif updating flags now that we hold the lock over the
full query.
* Explain various comments in more detail.
* Serialize acpi_battery_get_battdesc(), acpi_battery_register(), and
acpi_battery_remove().
* Assert that the sx lock is held in acpi_batteries_init().
* Remove check for device_get_softc() returning NULL.
* Serialize notification of acline changes in acpi_acad_get_status().
* Remove the initializing flag. With the locking, we don't need to
push off requests for the acline before initialization is done.
* Don't check device_get_softc(), it can't return NULL.
* Serialize calls to acpi_alloc_resource(), acpi_release_resource(),
acpi_Enable(), acpi_Disable(), and acpi_debug_sysctl().
* Acquire the ACPI mutex in acpi_register_ioctl(), acpi_deregister_ioctl(),
and acpiioctl().
* Acquire the mutex while disabling subsequent requests to enter a
sleep state in acpi_SetSleepState().
* Be sure to re-enable sleep requests and don't run resume methods when
the current request fails.
* Don't check if sleep requests are disabled in the ACPIIO_SETSLPSTATE
ioctl. acpi_SetSleepState() does this for us.
* Remove the acquisition of Giant from the struct cdevsw.
* Remove the ACPI_USE_THREADS option.
* Add and comment our locking primitives. The mutex primitives use a
a static mutex and the serialization ones use a static sx lock. A global
acpi_mutex is used for access to global resources (i.e., writes to the
SMI_CMD register.)
* Remove 4.x compat defines.

changes, although one release note, about udav(4) promiscuous mode,
was deleted as it was redundant (the driver itself is new and this
fact has its own note).
Since the only thing truly unique about a prison is it's ID, I figured
this would be the most granular way of handling this.
This commit makes the following changes:
- Adds tokenizing and parsing for the ``jail'' command line option
to the ipfw(8) userspace utility.
- Append the ipfw opcode list with O_JAIL.
- While Iam here, add a comment informing others that if they
want to add additional opcodes, they should append them to the end
of the list to avoid ABI breakage.
- Add ``fw_prid'' to the ipfw ucred cache structure.
- When initializing ucred cache, if the process is jailed,
set fw_prid to the prison ID, otherwise set it to -1.
- Update man page to reflect these changes.
This change was a strong motivator behind the ucred caching
mechanism in ipfw.
A sample usage of this new functionality could be:
ipfw add count ip from any to any jail 2
It should be noted that because ucred based constraints
are only implemented for TCP and UDP packets, the same
applies for jail associations.

subset ("compatible", "device_type", "model" and "name") of the standard
properties in drivers for devices on Open Firmware supported busses. The
standard properties "reg", "interrupts" und "address" are not covered by
this interface because they are only of interest in the respective bridge
code. There's a remaining standard property "status" which is unclear how
to support properly but which also isn't used in FreeBSD at present.
This ofw_bus kobj-interface allows to replace the various (ebus_get_node(),
ofw_pci_get_node(), etc.) and partially inconsistent (central_get_type()
vs. sbus_get_device_type(), etc.) existing IVAR ones with a common one.
This in turn allows to simplify and remove code-duplication in drivers for
devices that can hang off of more than one OFW supported bus.
- Convert the sparc64 Central, EBus, FHC, PCI and SBus bus drivers and the
drivers for their children to use the ofw_bus kobj-interface. The IVAR-
interfaces of the Central, EBus and FHC are entirely replaced by this. The
PCI bus driver used its own kobj-interface and now also uses the ofw_bus
one. The IVARs special to the SBus, e.g. for retrieving the burst size,
remain.
Beware: this causes an ABI-breakage for modules of drivers which used the
IVAR-interfaces, i.e. esp(4), hme(4), isp(4) and uart(4), which need to be
recompiled.
The style-inconsistencies introduced in some of the bus drivers will be
fixed by tmm@ in a generic clean-up of the respective drivers later (he
requested to add the changes in the "new" style).
- Convert the powerpc MacIO bus driver and the drivers for its children to
use the ofw_bus kobj-interface. This invloves removing the IVARs related
to the "reg" property which were unused and a leftover from the NetBSD
origini of the code. There's no ABI-breakage caused by this because none
of these driver are currently built as modules.
There are other powerpc bus drivers which can be converted to the ofw_bus
kobj-interface, e.g. the PCI bus driver, which should be done together
with converting powerpc to use the OFW PCI code from sparc64.
- Make the SBus and FHC front-end of zs(4) and the sparc64 eeprom(4) take
advantage of the ofw_bus kobj-interface and simplify them a bit.
