-unifdef
-since the roothub attach doesn't use locators, don't call
config_stdsubmatch() -- it is a no-op in that case
-ifsubmatch has configuration and interface always set to useful values,
remove unnecessary checks
-remove now unused locator definitions from shared header
than a zero-terminated list; this makes the code simpler and also
hopefully fixes the recent "childdet" botch, see PR kern/38528
-handle the root hub specially a bit earlier, this allows to kick out
the "submatch" functions completely which needed to second-guess
from the port number (where "0" meant root hub")
(we could handle the root hub specially even earlier, but as done
now big parts of the hub emulation code are exercised regularely,
this would bitrot otherwise)
proclist_mutex and proclist_lock into a single adaptive mutex (proc_lock).
Implications:
- Inspecting process state requires thread context, so signals can no longer
be sent from a hardware interrupt handler. Signal activity must be
deferred to a soft interrupt or kthread.
- As the proc state locking is simplified, it's now safe to take exit()
and wait() out from under kernel_lock.
- The system spends less time at IPL_SCHED, and there is less lock activity.
- Add a lot of missing selinit() and seldestroy() calls.
- Merge selwakeup() and selnotify() calls into a single selnotify().
- Add an additional 'events' argument to selnotify() call. It will
indicate which event (POLL_IN, POLL_OUT, etc) happen. If unknown,
zero may be used.
Note: please pass appropriate value of 'events' where possible.

Register _childdetached methods with drivers that attach children.
Wait to set child references to NULL there, instead of doing that
in the detach method.
Replace many uses of USB_DECLARE_DRIVER() with CFATTACH_DECL2().
-> the current names are confusing (didn't change other drivers)
* fix invalid memory access in usbd_transfer (kern/24636)
-> needed for this driver
* fix USB HC detach race condition (kern/32011)
-> main patch needed for this driver, sc_dying changes in other drivers
not necessary but seem right to me
Patch from Matthew Orgass.

one for tasks of the host controllers. This is needed for drivers like
ural(4) that want to do synchronous USB transfers from the task handler.
Before the split timeouts could not be handled correctly as the task
thread was still blocked. From FreeBSD.
- use vmspace rather than proc or lwp where appropriate.
the latter is more natural to specify an address space.
(and less likely to be abused for random purposes.)
- fix a swdmover race.
allocate a "struct usb_event" on stack in usb_add_event().
This gives just enough breathing space that the box doesn't die
immediately from stack overflow when I insert a
ohci0 at cardbus0 dev 0 function 0: Acer Labs M5237 USB 1.1 Host Controller
be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
Bump the kernel rev up to 1.6V
kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals
kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)
based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe
This merge changes the device switch tables from static array to
dynamically generated by config(8).
- All device switches is defined as a constant structure in device drivers.
- The new grammer ``device-major'' is introduced to ``files''.
device-major <prefix> char <num> [block <num>] [<rules>]
- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.
- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.
- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.
- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.
- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.
- implement SIMPLEQ_REMOVE(head, elm, type, field). whilst it's O(n),
this mirrors the functionality of SLIST_REMOVE() (the other
singly-linked list type) and FreeBSD's STAILQ_REMOVE()
- remove the unnecessary elm arg from SIMPLEQ_REMOVE_HEAD().
this mirrors the functionality of SLIST_REMOVE_HEAD() (the other
singly-linked list type) and FreeBSD's STAILQ_REMOVE_HEAD()
- remove notes about SIMPLEQ not supporting arbitrary element removal
- use SIMPLEQ_FOREACH() instead of home-grown for loops
- use SIMPLEQ_EMPTY() appropriately
- use SIMPLEQ_*() instead of accessing sqh_first,sqh_last,sqe_next directly
- reorder manual page; be consistent about how the types are listed
- other minor cleanups
