__FreeBSD_kernel__ indicates that this system uses the kernel of FreeBSD,
which by definition is always true on FreeBSD. This macro is also defined
on other systems that use the kernel of FreeBSD, such as GNU/kFreeBSD.
It is tempting to use this macro in userland code when we want to enable
kernel-specific routines, and in fact it's fine to do this in code that
is part of FreeBSD itself. However, be aware that as presence of this
macro is still not widespread (e.g. older FreeBSD versions, 3rd party
compilers, etc), it is STRONGLY DISCOURAGED to check for this macro in
external applications without also checking for __FreeBSD__ as an
alternative.

vnode locking for read, readdir, readlink, getattr and access.
It is hoped that this will improve server performance for these
operations, since they will no longer be serialized for a given
file/vnode.
This fixes panics that users have been seeing when operating in station mode,
where the interface undergoes a lot more resets then in hostap mode (ie whilst
doing channel scanning.)

Manual pages from OpenSolaris svn_134 are still properly CDDL licensed
but I have been informed that the parts from s11ex are uncertain even
if they contain a CDDL header.
- Don't deduct wired pages from total usable counts because it does not
make any sense. To make things worse, on systems where swap size is
smaller than physical memory and use a lot of wired pages (e.g. ZFS),
tmpfs can suddenly have free space of 0 because of this;
- Count cached pages as available; [1]
- Don't count inactive pages as available, technically we could but that
might be too aggressive; [1]

The dcache flush has to be done using the core control registers before
splitting the L1D cache by enabling the hardware threads.
Also replace .word calls for mfcr/mtcr with a C macro.

structs ifreq/in_aliasreq and there've been several panics due
to that problem. All these panics were fixed just a couple of
lines above the panicing code.
Take a more general approach: sanity check sockaddrs supplied
with SIOCAIFADDR and SIOCSIF*ADDR at the beggining of the
function and drop all checks below.
One check is now disabled due to strange code in ifconfig(8)
that I've removed recently. I'm going to enable it with next
__FreeBSD_version bump.
Historically in_ifinit() was able to recover from an error
and restore old address. Nowadays this feature isn't working
for all error cases, but for some of them. I suppose no software
relies on this behavior, so I'd like to remove it, since this
simplifies code a lot.
Also, move if_scrub() earlier in the in_ifinit(). It is more
correct to wipe routes before removing address from local
address list, and interface address list.

This assumption is invalid and the code should be fixed, but humor it for
now and set the "IPI" for PS3s in the non-SMP case to a large number. This
fixes boot with a non-SMP kernel.

current feed-forward ffcounter value. This enables new possibilities including
comparison of timekeeping performance and timestamp correction during post
