Some buggy firmware workarounds. Fix some endian bugs.
These reduce the diffs from NetBSD, but NetBSD does have more changes since
my last manual merge.
Link if only ATAPI device in kernel config
Remove unused #includes
Rearrange a bit in ata-raid to make diff against -stable smaller
Enable wc as default again, dunne how this happend...
This makes other power-management system (APM for now) to be able to
generate power profile change events (ie. AC-line status changes), and
other kernel components, not only the ACPI components, can be notified
the events.
- move subroutines in acpi_powerprofile.c (removed) to kern/subr_power.c
- call power_profile_set_state() also from APM driver when AC-line
status changes
- add call-back function for Crusoe LongRun controlling on power
profile changes for a example
Add code to properly detach/attach disks that are part of a RAID.
Mark a disk that is attached on an ATA channel belonging to a
RAID as a spare disk that can be used for rebuilding failed RAID1's.
Add support for rebuilding failed RAID1's.
Several fixes to the detach/attach code.
For replacing a disk in a failed RAID1 do the following:
Find the controller channel# of the failed disk.
Exec 'atacontrol detach <channel#>' to free the disk from the system.
Replace the failed disk with a new one of at least the same size.
If your have your disks in drawers/enclosures this can be done with
the system still running.
Exec 'atacontrol attach <channel#>' to add the disk to the system and
mark it as a valid spare for rebuild.
Exec 'atacontrol rebuild <array#>'
The system will rebuild the array on the fly, the array can still
be used during this, although with slower performance.
Please let me know of any problems with this!

MFC after: 2 weeks
in most machines of the Sun Ultra series. This is a port of the NetBSD
driver which I enhanced to make use of the gather functionality and the
configurable RX buffer offset to avoid copying all received/sent packet
(instead, packets will be directly DMAd from mbuf chains and into mbuf
clusters now).
device drivers for bus system with other endinesses than the CPU (using
interfaces compatible to NetBSD):
- bwap16() and bswap32(). These have optimized implementations on some
architectures; for those that don't, there exist generic implementations.
- macros to convert from a certain byte order to host byte order and vice
versa, using a naming scheme like le16toh(), htole16().
These are implemented using the bswap functions.
- stream bus space access functions, which do not perform a byte order
conversion (while the normal access functions would if the bus endianess
differs from the CPU endianess).
htons(), htonl(), ntohs() and ntohl() are implemented using the new
functions above for kernel usage. None of the above interfaces is currently
exported to user land.
Make use of the new functions in a few places where local implementations
of the same functionality existed.

functions that are now static.
This work is similar to work Justin posted to the mobile list about a
year or two ago, which I have neglected since then.
This is a subset of his current work with the multiple inheritance
newbus architecutre. When completed, that will eliminate the need for
pci/pci_private.h.
Similar work is needed for the cardbus_cis and pccard_cis code as well.
the inter-value histogram for 2000 samples. If the width is 3 or less
for 10 consequtive samples, we trust the counter to be good, otherwise
we use the *_safe() method.
This method may be too strict, but the worst which can happen is that
we take the performance hit of the *_safe() method when we should not.
Make the *_safe() method more discriminating by mandating that the three
samples do not span more than 15 ticks on the counter.
Disable the PCI-ident based probing as a means to recognize good
counters.
Inspiration from: dillon and msmith
latch the acpi timer, resulting in weird deltas. The problem is severe
enough to adversely effect the timecounter code.
Default to the 'safe' version of the get-timecount function. The probe
will override it if a known-good chipset is found. This is temporary
until a more complete solution is found.

AIOGCAP ioctl reports software-emulated formats. It defaults to on. People
who use performance-sensitive audio software and do not want it to pick a
software-emulated audio format instead of one supported by their hardware
should turn it off.
This unbreaks isdnphone(1) on systems with PCM-only sound cards.
