The vge driver has been added to GENERIC for i386, pc98 and amd64,
but not to sparc or ia64 since I don't have the ability to test
it there. The vge(4) driver supports VLANs, checksum offload and
jumbo frames.
Also added the lge(4) and nge(4) drivers to GENERIC for i386 and
pc98 since I was in the neighborhood. There's no reason to leave them
out anymore.

allow us to preserve binary compatibility on RELENG_5 when these facilities
are MFC'ed.

geom_uzip module. This is based on utility I wrote some 3 years ago for a
hack for md(4), which functionally was close to what geom_uzip does today.
Since I don't have a time to test that it compiles/works on other arches,
stick it to i386 only. Will do it later.
Unlike original cloop util, this one embedds FreeBSD-compatible shell code
into the generated image, not Linux one. Unfortunately severe space
restriction imposed by the CLOOP format doesn't allow to put conditional
code which will work both on Linux and FreeBSD. In fact it was quite a
challenge to fit necessary FreeBSD code into 127 bytes. ;-)
caused by refering broken (uninitialized?) pointer which is retrieved
from __bt_new() (and from mpool_new()).
I don't know why this linp[0] is read before stored because this
should be controlled by .lower and .upper member of PAGE structure
which are correctly initialized.
But this workaround fixes the problem on my environment and this
module has #ifdef PURIFY option which initializes new and reused
memory from mpool by memset(p, 0xff, size) like as I did.
Please feel free to fix the real bug instead of my workaround.
holds sndstat_lock across a call to uiomove(), which is not legal
to do with a mutex because of the possibility that the data transfer
could sleep because of a page fault. It is not possible to just
unlock the mutex for the uiomove() call without introducing another
locking mechanism to prevent the body of sndstat_read() from being
re-entered. Converting sndstat_lock to an sx lock is the least
complicated change.
This is a candidate for RELENG_5.

example the maximum segment size is 64K while the boundary is set
to 8K due to controller limitations. It is impossible to NOT cross
the boundary for any segment size that's larger than the boundary.
So, once we inherited the boundary from the parent tag, make sure
to reduce the maximum segment size to the boundary if it was larger.

branch prediction optimization for LINT, because the kernel was too
large. This commit now removes it altogether since it causes build
failures for GENERIC kernels and the various applicable trends are
such that one can expect that it these failure will cause more
problems than they're worth in the future. These trends include:
1. Alpha was demoted from tier 1 to tier 2 due to lack of active
support. The number of people willing to fix build breakages
is not likely to increase and those developers that do have the
gumption to test MI changes on alpha are not likely to spend
time fixing unexpected build failures first.
2. The kernel will only increase in size. Even though stripped-down
kernels do link without problems now, compiler optimizations (like
inlining) and new (non-optional) functionality will likely cause
stripped-down kernels to break in the future as well.
So, with my asbestos suit on, get rid of potential problems before
they happen.

redundant at this point and should be retired). Don't free subdevs if
we don't attach any devices. This was leaving stale device_t's
around. Don't touch the device if it isn't attached since the name
isn't meaningful then. Switch from strncpy (properly used) to
strlcpy.

we need to remember them.
# The usbd_device_handle->subdevs[] array likely is completely bogus

produced better results for a test program I had here, it didn't
substantially change the number of crashes that I saw. Both the old
code and the new code seemed to produce the same crashes from the usb

until the underlying issues wrt devices going away can be addressed.
It specifies the default number of retries per a name server.
This makes the code consistent with the manpage and allows to
kill another constant in res_init.c that should have been a
#define'd parameter. (This appears to be a case when the manpage
was better than the code, so the latter was to be fixed.)

Allowing the installation of labels addressing as much of the disk as
possiable may be a useful addition in some situations, but this was easy
to implement and should reduce confusion.

BPFD_LOCK() when removing a descriptor from an interface descriptor
list. Hold both over the operation, and do a better job at
maintaining the invariant that you can't find partially connected
descriptors on an active interface descriptor list.
This appears to close a race that resulted in the kernel performing
a NULL pointer dereference when BPF sessions are detached during
heavy network activity on SMP systems.

Fix the autoh_freeall(3) function to properly free the array of

OK, however it was then advancing the pointer and freeing the wrong
data for the whole list.
