1ecb38a365 Introduce two flags to control upcall behaviour: 
o KMF_NOUPCALL
	Ask kse_release to not return to userland upcall entry, but instead
	direct returns to userland by using current thread's stack and return
	address on stack. This flags is intended to be used by UTS in critical
	region to wait another UTS thread to leave critical region, by using
	kse_release with this flag to avoid spinnng and burning CPU. Also this
	flags can be used by UTS to poll completed context when there is nothing
	to do in userland and needn't restart from its entry like normal upcall.

o KMF_NOCOMPLETED
	Ask kernel to not bring completed thread contexts back to userland when
	doing upcall, this flags is intend to be used with above flag when an
	upcall thread is in critical region and can not process completed contexts
	at that time.

d647a0ed5a - Assert that the vm_object is locked in vm_object_clear_flag(), 
vm_object_pip_add() and vm_object_pip_wakeup().
 - Remove GIANT_REQUIRED from vm_object_pip_subtract() and
   vm_object_pip_subtract().
 - Lock the vm_object when performing vm_object_page_remove().

e22b0bf4b8 Fix /dev/devctl's implementation of poll. We should only be setting 
the poll bits when there's actually something in the queue.
Otherwise, select always returned '2' when there were no items to be
read, and '3' when there were.  This would preclude being able to read
in a threaded (libc_r) program, as well as checking to see if there
were pending events or not.

87b4a25958 Add device driver support for the ASIX Electronics AX88172 USB 2.0 
ethernet controller. The driver has been tested with the LinkSys
USB200M adapter. I know for a fact that there are other devices out
there with this chip but don't have all the USB vendor/device IDs.

Note: I'm not sure if this will force the driver to end up in the
install kernel image or not. Special magic needs to be done to exclude
it to keep the boot floppies from bloating again, someone please
advise.

3566dff0d9 - Enable interrupts only at the end of epic_attach() when all the 
other initializations succeeded.
- Initialize the TX and RX rings in epic_attach() rather than in
  epic_init() where we're not supposed to fail.  Similarly, free
  the TX and RX rings in epic_detach() rather than in epic_stop().
- Change epic_init() to be a void function now that it can't fail.
  Also change its parameter to a void * so that we have a correct
  prototype for if_init.
- Now that epic_init() has a correct prototype, don't cast the
  function pointer when initializing if_init.
- Fix nearby style bugs.

8a2ec7627f Various cleanups: 
- Don't initialize if_output, ether_ifattach() does this for us.
- Use pci_enable_busmaster() instead of using pci_read_config()
  and pci_write_config() directly.
- Don't try to enable I/O, bus_alloc_resource() does this for us.
