specific macros for each audit argument type. This makes it easier to
follow call-graphs, especially for automated analysis tools (such as
fxr).
In MFC, we should leave the existing AUDIT_ARG() macros as they may be
used by third-party kernel modules.

in one additional case, avoiding an ifaddr reference leak.
Defer releasing the in6_ifaddr's in6_ifaddrhead reference until the
end of in6_unlink_ifa(), as callers are inconsistent regarding whether
or not they hold a reference across the call. This avoids using the
ifaddr after it may have been freed.

IF_ADDR_UNLOCK() across network device drivers when accessing the
per-interface multicast address list, if_multiaddrs. This will
allow us to change the locking strategy without affecting our driver
programming interface or binary interface.
For two wireless drivers, remove unnecessary locking, since they
don't actually access the multicast address list.

vm_cache_mode_t with an appropriate VM_CACHE_DEFAULT definition on all
architectures. In addition, this changes adds a vm_cache_mode_t parameter
to kmem_alloc_contig() and vm_phys_alloc_contig(). These will be the

respectively, with non-default cache modes.

allow them to start after netif. There were too many problems reported
with this change in the short period of time that it lived in HEAD, and
we are too late in the release cycle to properly shake it out.
IMO the issue of having the firewalls up before the network is still a
valid concern, particularly for pf whose default state is wide open.
However properly solving this issue is going to take some investment
on the part of the people who actually use those tools.
This is not a strict reversion of all the changes for r193198 since it
also included some simplification of the BEFORE/REQUIRE logic which is
still valid for ipfilter and ip6fw.
if_addr_rlock() and if_addr_runlock() for regular address lists, and
if_maddr_rlock() and if_maddr_runlock() for multicast address lists.
We will use these in various kernel modules to avoid encoding specific
type and locking strategy information into modules that currently use
IF_ADDR_LOCK() and IF_ADDR_UNLOCK() directly.

vfs.ufs.dirhash_maxmem below the current amount of memory used by dirhash. When
ufsdirhash_build() is called with the memory in use greater than dirhash_maxmem,
it attempts to free up memory by calling ufsdirhash_recycle(). If successful in
freeing enough memory, ufsdirhash_recycle() leaves the dirhash list locked. But
at this point in ufsdirhash_build(), the list is not explicitly unlocked after
the call(s) to ufsdirhash_recycle(). When we next attempt to lock the dirhash
list, we will get a "panic: _mtx_lock_sleep: recursed on non-recursive mutex
dirhash list".

However, since cdevsw already maintains a version field, new versions
