don't. Ignore timeout errors to keep old behavior when error there was
impossible.
For me this fixes timeout errors on the first command after channel attach
or reinit. Boot in my case is not affected, as there is much time passing
between reset and next command giving reset time to complete.

and partially r188903. Revert breaks new drives detection on reinit to the
state as it was before me, but fixes series of new bugs reported by some
people.
Unconditional queueing of ata_completed() calls can lead to deadlock if
due to timeout ata_reinit() was called at the same thread by previous
ata_completed(). Calling of ata_identify() on ata_reinit() in current
implementation opens numerous races and deadlocks.
Problems I was touching here are still exist and should be addresed, but
probably in different way.
drivers' probe routines. It allows not to sleep and so not drop Giant inside
ata_identify() critical section and so avoid crash if it reentered on
request timeout. Reentering of probe call checked inside of it.
Give device own knowledge about it's type (ata/atapi/atapicam). It is not
a good idea to ask channel status for device type inside ata_getparam().
Add softc memory deallocation on device destruction.
at irq install/uninstall time, but when we vt switch, we uninstall the
irq handler. When the irq handler is reinstalled, the modeset ioctl
happens first. The modeset ioctl is supposed to tell us that we can
disable vblank interrupts if there are no active consumers. This will
fail after a vt switch until another modeset ioctl is called via dpms
or xrandr. Leading to cases where either interrupts are on and can't
be disabled, or worse, no interrupts at all.

The /dev entries are layed out as follows,
/dev/usbctl = master device
/dev/usb/0.1.0.5 = usb device, (<bus>.<dev>.<iface>.<endpoint>)
/dev/ugen0.1 -> usb/0.1.0.0 = ugen link to ctrl endpoint
This also removes the custom permissions model from USB. Bump

net/route.h.
Remove the hidden include of opt_route.h and net/route.h from net/vnet.h.
We need to make sure that both opt_route.h and net/route.h are included
before net/vnet.h because of the way MRT figures out the number of FIBs
from the kernel option. If we do not, we end up with the default number
of 1 when including net/vnet.h and array sizes are wrong.
This does not change the list of files which depend on opt_route.h
but we can identify them now more easily.
kernel dumping case.
ata_completed() may initiate ata_reinit() on error, that may lead to drives
attach or detach. Attach and detach are sending requests to drives and sleep
waiting for results. But ata_finish() can be called directly from
interrupt handler where sleeping is prohibited, so we must break this chain
somewhere. This place seems to fit best.
Disable MSI for nVidia MCP51 controller. Enabling MSI there leads to
unexpected errors and timeouts, that should not happen even if interrupts
are not working completely.

- We don't need to exit the Giant mutex when sleeping. This is done
automatically. Replace Giant by NULL mutex for all control requests in the
enumeration path.
- Optimise away duplicate alternate interface selection requests in USB Host
mode.

Improvements to "usb2_transfer_setup()" and "usb2_transfer_unsetup()". Set
"ppxfer[n]" when the transfer setup is complete to prevent races. Remove
redundant NULL-checks from "usb2_transfer_unsetup()".

- The software computed HID size is not always correct, because the algoritm
does not handle unsorted HID descriptors.
- Change the way we obtain the report ID.
- Use the X/Y/Z+button locations instead for report ID source for ums.
- Add more range checks.
- Remove Microsoft Mouse quirks. If the positions are moduloed the report
length multiplied by 8, the values seem correct.
- Some minor style changes.
