boundaries. For good measure, align all other objects to cache
lines boundaries.
Use the new arch_loadseg I/F to keep track of kernel text and
data so that we can wire as much of it as is possible. It is
the responsibility of the kernel to link critical (read IVT
related) code and data at the front of the respective segment
so that it's covered by TRs before the kernel has a chance to
add more translations.
Use a better way of determining whether we're loading a legacy
kernel or not. We can't check for the presence of the PBVM page
table, because we may have unloaded that kernel and loaded an
older (legacy) kernel after that. Simply use the latest load
address for it.
1. arch_loadaddr - used by platform code to adjust the address at which
the object gets loaded. Implement PC98 using this new interface instead
of using conditional compilation. For ELF objects the ELF header is
passed as the data pointer. For raw files it's the filename. Note that
ELF objects are first considered as raw files.
2. arch_loadseg - used by platform code to keep track of actual segments,
so that (instruction) caches can be flushed or translations can be
created. Both the ELF header as well as the program header are passed
to allow platform code to treat the kernel proper differently from any
additional modules and to have all the relevant details of the loaded
segment (e.g. protection).
- Add more fields for USB device and host mode
- Add more information to USB PF header so that decoding
can easily be done by software analyzer tools like
Wireshark.
- Optimise usbdump to display USB streams in text format
more efficiently.
- Software using USB PF must be recompiled after
this commit, due to structure changes.

Update for SouthAmerica/Chili:
- Chile's clocks will go back an hour this year on the 7th of May instead
of this Saturday. They will go forward again the 3rd Saturday in
August, not in October as they have since 1968. This is a pilot plan
which will be reevaluated in 2012.

- In softdep_revert_mkdir() find the dotaddref before we attempt to cancel
the jaddref so we can make assumptions about where the dotaddref is on
the list. cancel_jaddref() does not always remove items from the list
anymore.
- Always set GOINGAWAY on an inode in softdep_freefile() if DEPCOMPLETE
was never set. This ensures that dependencies will continue to be
processed on the inowait/bufwait list and is more an artifact of
the structure of the code than a pure ordering problem.
- Always set DEPCOMPLETE on canceled jaddrefs so that they can be freed
appropriately. This normally occurs when the refs are added to the
journal but if they are canceled before this point the state would
never be set and the dependency could never be freed.

There is a generic problem with the shims for ioctls that receive
pointers to the usermode data areas in the data argument. We either have
to modify the handler to accept UIO_USERSPACE/UIO_SYSSPACE indicator, or
allocate and fill a usermode memory for data buffer in the host format.
The change goes the second route, in particular because we do not need
to modify the handler.

GEOM GATE to fix the issue described in r220264. This also means that we no
longer need -q option, remove it. Don't bother to leaving it as a no-op, as
ggatel(8) is just an example utility.
g_io_deliver(). In such case it increases 'pace' counter on each ENOMEM and
reschedules the request. The 'pace' counter is decreased for each request going
down, but until 'pace' is greater than zero, GEOM will handle at most 10
requests per second. For GEOM GATE users that are proxy to local GEOM providers
(like ggatel(8) and HAST) we can end up with almost permanent slow down of GEOM
down queue. This is because once we reach GEOM GATE queue limit, we return
ENOMEM to the GEOM. This means that we have, eg. 1024 I/O requests in the GEOM
GATE queue. To make room in the queue and stop returning ENOMEM we need to
proceed the requests of course, but those requests are handled by userland
daemons that handle them by reading/writing also from/to local GEOM providers.
For example with HAST, a new requests comes to /dev/hast/data, which is GEOM
GATE provider. GEOM GATE passes the request to hastd(8) and hastd(8)
reads/writes from/to /dev/da0. Once we reach GEOM GATE queue limit, to free up
a slot in GEOM GATE queue, hastd(8) has to read/write from/to /dev/da0, but
this request will also be very slow, because GEOM now slows down all the
requests. We end up with full queue that we can unload at the speed of 10
requests per second. This simply looks like a deadlock.
Fix it by allowing userland daemons that work with both GEOM GATE and local
GEOM providers to specify unlimited queue size, so GEOM GATE will never return
ENOMEM to the GEOM.

Some devices (eg the TPLink WR-1043ND) don't have a flash environment
partition which can be queried for the current board settings.
This particular workaround allows for image creators to use a hint

If you specify enough WITHOUT_FOO flags, the argument list passed to the
