512824f8f7 - Implement selwakeuppri() which allows raising the priority of a
thread being waken up.  The thread waken up can run at a priority as
  high as after tsleep().

- Replace selwakeup()s with selwakeuppri()s and pass appropriate
  priorities.

- Add cv_broadcastpri() which raises the priority of the broadcast
  threads.  Used by selwakeuppri() if collision occurs.

ed692400eb I don't know from where the notion that device driver should or
even could call VOP_REVOKE() on vnodes associated with its dev_t's
has originated, but it stops right here.

If there are things people belive destroy_dev() needs to learn how to
do, please tell me about it, preferably with a reproducible test case.

Include <sys/uio.h> in bluetooth code rather than rely on <sys/vnode.h>
to do so.

The fact that some of the USB code needs to include <sys/vnode.h>
still disturbs me greatly, but I do not have time to chase that.

7ac40f5f59 Gigacommit to improve device-driver source compatibility between
branches:

Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.

This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

	Two major changes:

	  Make each xfer have its own intr_info.  This is necessary if we want

	  (mostly harmless) DIAGNOSTICs about intr_infos (not) being done.

	  Change (again!) how xfers are aborted.  Aborting a TD is a nightmare

85f190e4d1 Fixes to make select/poll mpsafe.
Problem:
  selwakeup required calling pfind which would cause lock order
  reversals with the allproc_lock and the per-process filedesc lock.
Solution:
  Instead of recording the pid of the select()'ing process into the
  selinfo structure, actually record a pointer to the thread.  To
  avoid dereferencing a bad address all the selinfo structures that
  are in use by a thread are kept in a list hung off the thread
  (protected by sellock).  When a selwakeup occurs the selinfo is
  removed from that threads list, it is also removed on the way out
  of select or poll where the thread will traverse its list removing
  all the selinfos from its own list.

Problem:
  Previously the PROC_LOCK was used to provide the mutual exclusion
  needed to ensure proper locking, this couldn't work because there
  was a single condvar used for select and poll and condvars can
  only be used with a single mutex.
Solution:
  Introduce a global mutex 'sellock' which is used to provide mutual
  exclusion when recording events to wait on as well as performing
  notification when an event occurs.

Interesting note:
  schedlock is required to manipulate the per-thread TDF_SELECT
  flag, however if given its own field it would not need schedlock,
  also because TDF_SELECT is only manipulated under sellock one
  doesn't actually use schedlock for syncronization, only to protect
  against corruption.

Proc locks are no longer used in select/poll.

a6d9a40e81 More USB ethernet tweaks:
- Sync ohci, uhci and usbdi modules with NetBSD in order to obtain the
  following improvements:
        o New USBD_NO_TSLEEP flag can be used in place of UQ_NO_TSLEEP
          quirk. This allows drivers to specify busy waiting only for
          certain transfers (namely control transfers for reading/writing
          registers and stuff).
        o New USBD_FORCE_SHORT_XFER flag can be used to deal with
          devices like the ADMtek Pegasus that sense the end of bulk OUT
          transfers in a special way (if a transfer is exactly a multiple
          of 64 bytes in size, you need to send an extra empty packet
          to terminate the transfer).
        o usbd_open_pipe_intr() now accepts an interval argument which
          can be used to change the rate at which the interrupt callback
          routine is invoked. Specifying USBD_DEFAULT_INTERVAL uses the
          value specified in the device's config data, but drivers can
          override it if needed.
- Change if_aue to use USBD_FORCE_SHORT_XFER for packet transmissions.
- Change if_aue, if_kue and if_cue to use USBD_NO_TSLEEP for all
  control transfers. We no longer force the non-tsleep hack for
  bulk transfers since these are done asynchronously anyway.
- Removed quirk entry fiddling from if_aue and if_kue since we don't
  need it anymore now that we have the USBD_NO_TSLEEP flag.
- Tweak ulpt, uhid, ums and ukbd drivers to use the new arg to
  usbd_open_pipe_intr().
- Add a flag to the softc struct in the ethernet drivers to indicate
  when a device has been detached, and use this flag to perform
  tests to prevent the drivers from trying to do control transfers
  if this is the case. This is necessary because calling if_detach()
  with INET6 enabled will eventually result in a call to the driver's
  ioctl() routine to delete the multicast groups on the interface,
  which will result in attempts to perform control transfers. (It's
  possible this also happens even without INET6 support enabled.) This
  is pointless since we know that if the detach method has been called,
  the hardware has been unplugged.
- Changed watchdog timeout routines to just call the driver init routines
  to initialize the device states without trying to close and re-open the
  pipes. This is partly because we don't want to frob things at interrupt
  context, but also because this doesn't seem to work right and I don't
  want to panic the system just because a USB device may have stopped
  responding.
- Fix aue_rxeof() to be a little smarter about detecting when a double
  transfer is needed. Unfortunately, the design of the chip makes it hard
  to get this exactly right. Hopefully, this will go away once either
  Nick or Lennart finds the bug in the uhci driver that makes this ugly
  hack necessary.
- Also sync usbdevs with NetBSD.

- Remove some unused code
- Other KNF changes

  account)

Add preliminary support for isochronous to the UHCI driver (not for OHCI
yet).

usb.c, uhci.c, ohci.c
- Initial attempt at detachable USB host controllers
- Handle the use_polling flag with a lttle more care and only set it if
we are cold booting.

usb.c, uhci.c ohci.c, usbdi.c usbdi_util.c usb_subr.c
- Make sure an aborted pipe is marked as not running.
- Start queued request in the right order.
- Insert some more DIAGNOSTIC sanity checks.
- Remove (almost) unused definitions USBD_XFER_OUT and USBD_XFER_IN.

usb.c, usb_subr.c
- Add an event mechanism so that a userland process can watch devices
  come and go.

ohci.c
- Handle the case when a USB transfer is so long that it crosses two
  page (4K) boundaries.  OHCI cannot do that with a single TD so we make
  a chain.

ulpt.c
- Use a bigger buffer when transferring data.
- Pre-allocate the DMA buffer.  This makes the driver slightly more
  efficient.
- Comment out the GET_DEVICE_ID code, because for some unknown reason it
  causes printing to fail sometimes.

usb.h
- Add a macro to extract the isoc type.
- Add a macro to check whether the routine has been entered after splusb
  and if not, complain.

usbdi.c
- Fix a glitch in dequeueing and aborting requests on interrupt pipes.
- Add a flag in the request to determine if the data copying is done by
  the driver or the usbdi layer.

0b0f3f6c3d The Qtronix keyboard has a built in PS/2 port for a mouse.
It however posts a bogus button up event once in a while. Whenever
we receive dx=dy=dz=buttons=0 we postpone adding it to the queue for
50msecs with a timeout. If in the meantime something else is posted
the event is ignored.

This avoids the problem Nik Sayer reported. He noticed that X windows
would drop and pick up a window once in a while.
