Once dpcpu goes NUMA this is considered to help debugging as well.

all pertinent statatistics for the subsystem. These structures are
sometimes "borrowed" by kernel modules that require a place to store
statistics for similar events.
Add KPI accessor functions for statistics structures referenced by kernel
modules so that they no longer encode certain specifics of how the data
structures are named and stored. This change is intended to make it
easier to move to per-CPU network stats following 8.0-RELEASE.
The following modules are affected by this change:
if_bridge
if_cxgb
if_gif
ip_mroute
ipdivert
pf
In practice, most of these statistics consumers should, in fact, maintain
their own statistics data structures rather than borrowing structures
from the base network stack. However, that change is too agressive for
this point in the release cycle.

The newbus lock is responsible for protecting newbus internIal structures,
device states and devclass flags. It is necessary to hold it when all
such datas are accessed. For the other operations, softc locking should
ensure enough protection to avoid races.
Newbus lock is automatically held when virtual operations on the device
and bus are invoked when loading the driver or when the suspend/resume
take place. For other 'spourious' operations trying to access/modify
the newbus topology, newbus lock needs to be automatically acquired and
dropped.
For the moment Giant is also acquired in some key point (modules subsystem)
in order to avoid problems before the 8.0 release as module handlers could
make assumptions about it. This Giant locking should go just after
the release happens.
Please keep in mind that the public interface can be expanded in order
to provide more support, if there are really necessities at some point
and also some bugs could arise as long as the patch needs a bit of
further testing.
Bump __FreeBSD_version in order to reflect the newbus lock introduction.

in prison_equal_ip4/6 while an inp mutex was held. Locking allprison_lock
can be avoided by making a restriction on the IP addresses associated with
jails:
Don't allow the "ip4" and "ip6" parameters to be changed after a jail is
created. Setting the "ip4.addr" and "ip6.addr" parameters is allowed,
but only if the jail was already created with either ip4/6=new or
ip4/6=disable. With this restriction, the prison flags in question
(PR_IP4_USER and PR_IP6_USER) become read-only and can be checked
without locking.
This also allows the simplification of a messy code path that was needed
to handle an existing prison gaining an IP address list.
