the sole purpose of which was to protect dirty on architectures which

Import the rest of HID improvements from the branch:
- improve report descriptor parser in libusbhid to handle several kinds of
reports same time;
- add to the libusbhid API two functions wrapping respective kernel IOCTLs
for reading and writing reports;
- tune uhid IOCTL interface to allow reading and writing arbitrary report,
when multiple supported by the device;
- teach usbhidctl to set output and feature reports;
- make usbhidaction support all the same item names as bhidctl.

Adjust raw_input() and split it into wrapper and a new function
taking an optional callback argument even though we only have one

rather than the whole beacon interval.
The reference driver and Linux ath9k both choose 80% of the
beacon interval and they do it in the driver rather than
the HAL (Ath reference) or ath9k_hw (ath9k.)
This quietens stuck beacon conditions on my AR9220/AR9280
based NICs when a lot of burst broadcast/multicast traffic
is going on. It doesn't seem to annoy the earlier MACs as
much as the AR9280 and later one.

local variable with a beacon interval of 100 TU. This never gets modified
if the beacon interval configuration changes.
This may have been correct in earlier times, but with the advent of
staggered beacons (which default to 1 / ATH_BCBUF beacon interval, so
25 TU here) this value is incorrect.
It is used to configure the default CABQ readytime. So here, the cabq
was being configured to be much greater than the target beacon timer
(TBTT.)
The driver should be configuring a cabq readytime value rather then
leaving it to the HAL to choose sensible defaults. This should be
done in the future - I'm simply trying to ensure sensible defaults
are chosen.
1. Allow the caller to select active mode.
2. Fix the envar logic so it *always* overrides the caller's flags.
3. Document the change from active to passive.
reads eating 100% CPU. Fix this by skipping select on STDIN after
reading EOF -- permanently if STDIN is not terminal and for one second
if it is.
Also after reading EOF from STDIN we have to pass it to the program
being scripted. The previous approach was to write zero bytes into the
pseudo-terminal. This does not work because zero-byte write does not
have any effect on read. Fix this by sending VEOF instead.

whle tracking down the system hang reported in kern/160662 and
corrected in revision 225806. The LOR is not the cause of the system
hang and indeed cannot cause an actual deadlock. However, it can
be easily eliminated by defering the acquisition of a buflock until
after all the vnode locks have been acquired.

When a status pointer is passed in mfi_dcmd_command does not return an
errno (if the ioctl is successful), so move the test for NO_HW_PRESENT
outside of the error case. This should fix incorrect reporting for
systems with a dead or no battery.
Additionally, handle error codes other than NO_HW_PRESENT by omitting
the battery capacity display. LSI's supercap-based parts (CV series)
report their data using the same interface as battery-based parts,
except that they do not include the capacity stats (state of charge,
cumulative charge cycles, etc.)

wdog_kern_pat() acquires eventhandler mutex, thus it cannot work in
kernel context (from where kdb_trap() runs).
The right way to fix this is both offering the
cpu-stop-on-panic-and-skip-locking logic and also a context for KDB
to officially run. We can re-enable this (or a similar) improvement
when these 2 patches hit the tree.
