Attach call without devclass set crashes the system.
On resume AHCI driver sometimes tries to create duplicate adX device.
It is surely his own problem, but IMHO it is not a reason to crash here.
Other reasons are also possible.
kernel one as the non-faulting flush address in the loader so
we can can change KERNBASE and VM_MIN_KERNEL_ADDRESS if we
ever want to without needing to worry about using a compatible
loader.
- Correctly check for LOADER_DEBUG.
- Add a missing const for page_sizes[].
result in errors for a format loading but subsequent correct recognizing
for another format.
File format loading functions should avoid printing any additional
informations but just returning appropriate (and different between each
other) error condition, characterizing different informations.
Additively, the linker should handle appropriately different format
loading errors.
While a general mechanism is desired, fix a simple and common case on
amd64: file type is not recognized for link elf and confuses the linker.
Printout an error if all the registered linker classes can't recognize
and load the module.

- Change "usb2_pause_mtx" so that it takes the timeout value in ticks
- Make sure that attach waits for the generic probe to leave room for firware
loader drivers and device specific USB Audio drivers like USB phone adapters

1. Move most of the ifnet logic into the usb2_ethernet module, this includes,
- make all usb ethernet interfaces named ue%d
- handle all threading in usb2_ethernet
- provide default ioctl handler
- handle mbuf rx
- provide locked callbacks for init,start,stop,etc
2. Cleanup CDC-Ethernet driver.

lookups:
- Honor the caller's locking flags in udf_root() and udf_vget().
- Set VV_ROOT for the root vnode in udf_vget() instead of only doing it in
udf_root().
- Honor the requested locking flags during pathname lookups in udf_lookup().
- Release the buffer holding the directory data before looking up the vnode
for a given file to avoid a LOR between the "udf" vnode locks and
"bufwait".
- Use vn_vget_ino() to handle ".." lookups.
- Special case "." lookups instead of calling udf_vget(). We have to do
extra checking for the vnode lock for "." lookups.
the same dma tag. However, it can happen multiple dma tags share the same
bounce zone too, so add a per-bounce zone map counter, and check it instead of
the dma tag map counter, to know if we have to alloc more pages.
