CVS commit: [jmcneill-usbmp] src/sys/dev

["matthew green" <mrg%netbsd.org@localhost>]

Module Name:    src
Committed By:   mrg
Date:           Fri Dec  9 01:53:00 UTC 2011

Modified Files:
        src/sys/dev/pci [jmcneill-usbmp]: ehci_pci.c ohci_pci.c uhci_pci.c
        src/sys/dev/usb [jmcneill-usbmp]: ehci.c ohci.c uaudio.c uhci.c umidi.c
            usb.c usb_subr.c usbdi.c usbdivar.h

Log Message:
- make pipe->close method take the thread lock

- convert usb_taskq to use mutex/cv

- convert needs_explore usage into a cv on the thread lock

- remove KERNEL_*LOCK from uaudio and umidi, since we're supposedly
  MPSAFE here now

- use IPL_SCHED instead of IPL_USB (aka biglocked) interrupts

- drop the audio thread lock when calling into usb when it may sleep,
  avoiding a deadlock between audiowrite and audioioctl.  this fixes
  mixerctl -a vs. playing hanging the system
  XXX probably need to check this in a bunch more places.
