simplify it a bit, and make use of that method to determine if an
interface is a candidate for IPv6 rtsol rather than listing all of the
possible wireless interfaces that should _not_ get rtsol'ed.
This change is only relevant for 8.0+ unless the "wlan mandatory" code
gets ported back to RELENG_7.
during the kernel build process, the other places that call the script
do not make use of that information. So restrict execution of the
svnversion-related code to the kernel build context.
to allow vnet and non vnet operation. Move some functions from ip_fw_pfil.c
to ip_fw2.c and mode to mostly using the SYSINIT and VNET_SYSINIT handlers
instead of the modevent handler. Correct some spelling errors in comments
in the affected code. Note this bug fixes a crash in NON VIMAGE kernels when
ipfw is unloaded.
This patch is a minimal patch for 8.0
I have a much larger patch that actually fixes the underlying problems
that will be applied after 8.0

leaving the new list empty.
- Properly compute the amount of data added to an sglist via
_sglist_append_buf(). This allows sglist_consume_uio() to properly update

network stack instances, which is provided for compatibility with
older applications. This change brings it back to life in a followup
to the initial conversion of vimage to use the new jail(4)
userland-kernel API:
- when creating vimages via "vimage -c", by default turn on a few
options expected by legacy applications, such as allow operations on
raw sockets, FS mounts etc, and allow jail-related parameters to be
optionally configured.
- introduce the "-m" modifier which allows for configuring jail
parameters of existing vimages / vnet-jails.
- make "vimage name command ..." actually work.
- when reassigning ifnets to vnets using "vimage -i", attempt to rename
the ifnet as "ethXXX" on arrival in the target vnet. Several legacy
applications are known to depend heavily on such behavior.
- vimage -l lists only jails associated with vnets. The output is
sorted using vimage / jail names as keys.
- vimage -l by default searches only the current level in the jail
hierarchy. Recursive listing can be requested via -r switch.
- vimage -l by default prints only jail names on each line, making
such output suitable for pipelining to other commands. More verbose
output can be obtained via -v switch, and even more jail specific
information will be displayed if -j switch is turned on.
- there's no need to build vimage as statically linked, so update the
Makefile accordingly.
- update the vimage.8 man page.

This affects only fstat on zfs and devfs, only on 64-bit systems
and only when fsid is greater than 2^31 - 1.
When fstat examines a file via stat(2) it takes uint32_t st_dev
and assigns to (signed) (64-bit) long fsid, this results in
a positive value.
When fstat examines opened files it takes int32_t f_fsid.val[0]
and assigns to (signed) (64-bit) long fsid, this results in
a negative value.
So, while initially st_dev and f_fsid.val[0] have the same bit
values they get promoted to different 64-bit values because
of the signed-vs-unsigned difference.
A fix is to use "more natural" positive numbers by introducing
intermediate unsigned cast for f_fsid.val[0].

- usb_pc_cpu_invalidate() is called between [consecutive] reads from a device,
so a sequence of BUS_DMASYNC_POSTREAD and _PREREAD should be used. Note we
cannot use or'ed shorthand ( _POSTREAD | _PREREAD) for BUS_DMASYNC flags, as
the low level bus dma sync operation is implementation dependent and we
cannot assume the required order of operations to be guaranteed.

when pmap_demote_pde() allocates a page table page to implement a
user-space demotion, it must increment the pmap's resident page count.
Not doing so, can lead to an underflow during address space termination
that causes pmap_remove() to exit prematurely, before it has destroyed
all of the mappings within the specified range. The ultimate effect or
symptom of this error is an assertion failure in vm_page_free_toq()
because the page being freed is still mapped.
This error is only possible when superpage promotion is enabled. Thus,
it only affects FreeBSD versions greater than 7.2.
