Note that only option names are printed, not values.

Drop USB mass storage devices support from ata(4). It is out of the build as
long as I remember, and completely superseded by better maintained umass(4).
It's main idea was to optionally avoid CAM dependency for such devices, but
with move ATA to CAM, it is not actual any more.

- Extend XPT-SIM transfer settings control API. Now it allows to report to
SATA SIM number of tags supported by each device, implement ATA mode and
SATA revision negotiation for both SATA and PATA SIMs.
- Make ahci(4) and siis(4) to use submitted maximum tag number, when
scheduling requests. It allows to support NCQ on devices with lower tags
count then controller supports.
- Make PMP driver to report attached devices connection speeds.
- Implement ATA mode negotiation between user settings, device and
controller capabilities.
- Improve ATA mode/SATA revision control.
- Fix several device freeze counting bugs.
- Remove code that years ago was closing race between request submission
to SIM and device/SIM freeze. That race become impossible after moving from
spl to mutex locking, while this workaround causes some unexpected effects.
Eliminate dead stores.
In __mbsconv(), if prec was zero, nconv could have been used
uninitialized. Initialize it to a safe value so that there's no
chance of returning an error if stack garbage happens to be equal to
(size_t)-1 or (size_t)-2.
In svc_raw_reply(), don't leave stat uninitialized if the MSG_ACCEPTED
&& SUCCESS case succeeds. The stack garbage might be zero.
In clnt_raw_create(), avoid minor race condition initializing the
file-scope variable clntraw_private.

- fix a LOR between process lock and pmc thread mutex
- fix a system deadlock on process exit when the sample buffer
is full (pmclog_loop blocked in fo_write) and pmcstat exit.
It seems generation of link state change of e1000phy(4) is not
reliable on some Marvell PHYs. If msk(4) know it still does not
have established link check whether msk(4) missed the link state
change by looking into polled link state.

r198996:
Remove unnecessary header file.
r198997:
It's normal to see Rx FIFO overruns under high network load and
showing the message creates other side-effects. Remove the Rx
FIFO overrun message in interrupt handler. msk(4) should recover
from the FIFO overruns without any user intervention. Users can
still check the Rx FIFO overrun counter from MAC MIB statistics
maintained in driver(dev.msk.0.stats.rx.overflows).
Add a check to know whether driver is still running after
reacquiring driver lock in Rx handler. re(4) drops a driver lock
before passing received frame to upper stack and reacquire the
lock. During the time window ioctl calls could be executed and if
the ioctl was interface down request, driver will stop the
controller and free allocated mbufs. After that when driver comes
back to Rx handler again it does not know what was happend so it
could access free mbufs which in turn cause panic.

For AR8132 fast ethernet controller, do not report 1000baseT
capability to mii(4). Even though AR8132 uses the same model/
revision number of F1 gigabit PHY, the PHY has no ability to
establish 1000baseT link. I have no idea why Atheros use the same
device/model id for this PHY.
With this change atphy(4) does not report 1000baseT media
capability and manual 1000baseT configuration is also disabled
which is more desirable behavior for 10/100Mbps PHY.
Add DGE-560SX(Yukon XL) to the supported device list. Many thanks
to "Eugene Perevyazko <john <> dnepro dot net>" who kindly gave
remote access to system with DGE-560SX.
Add hack to pass controller specific information to phy driver.
Unlike most other PHYs there is no easy way to know which media
type the PHY supports on Marvell PHYs. MIIF_HAVEFIBER flags is now
passed via bus-specific instance variable of a device. While I'm
here add 88E1112 specific work around to set SIGDET polarity low.

Provide a real fix to the too-many-translations problem when booting
from CD on 64-bit hardware to replace existing band-aids. This occurred
when the preloaded mdroot required too many mappings for the static
buffer.
Since we only use the translations buffer once, allocate a dynamic
buffer on the stack. This early in the boot process, the call chain
is quite short and we can be assured of having sufficient stack space.
SMP support for PowerPC G5 systems.
r198724:
Fix a race in casuword() exposed by csup. casuword() non-atomically
read the current value of its argument before atomically replacing it,
which could occasionally return the wrong value on an SMP system. This
resulted in user mutex operations hanging when using threaded applications.
r198723,198725,198731:
Loop on blocked threads when using ULE scheduler, removing an
XXX MP comment.
r198427:
Add some more paranoia to setting HID registers, and update the AIM
clock routines to work better with SMP.
r198378:
Add SMP support on U3-based G5 systems. While here, correct the
64-bit tlbie function to set the CPU to 64-bit mode correctly.
r198212:
Don't assume that physical addresses are identity mapped. This
allows the second processor on G5 systems to start.
Do not map the trap vectors into the kernel's address space. They are
only used in real mode and keeping them mapped only serves to make NULL
a valid address, which results in silent NULL pointer deferences.

Add sysctls in ahd(4) in order to keep track of different classes of
errors. So far 3 different classes are present (correctable,
uncorrectable and fatal) but more can be added easilly.

Add the possibility for vfs.root.mountfrom tunable to accept a list of
items rather than a single one.
While there fix also a nit in a comment.
