Also, make the interprocessor interlock the only thing on its cache line.

This completes the transition. A cvs log and diff will tell the story
of why we went through this.

private mail. We already have mount_ext2fs there, so it's likely to
be just forgotten to be enabled.
kirby@ kindly tested that kernel still fits.

Tested and ok joshe@

Because ext2fs has only 32-bit inode numbers, use ufsino_t as in FFS.
Disk blocks are u_int32_t as well, because we don't support the 64BIT flag.
When we do, there's going to be a lot more going on than just daddr_t.
While there, add some journaling-related bits into the superblock to play with.

We need to do these, but at a better time than right after a hackathon
and before release.

we can pull the space the mbuf layer used to do per interface accounting
out of struct if_data.
saves a hundredish bytes on every interface.

KASSERT() is annoying as it only prints the expression as a string. If you
(developers) want to know a little more information, you have to do:
#ifdef DIAGNOSTIC
if (bad)
panic(...);
#endif
KASSERTMSG() replaces it into a single line:
KASSERTMSG(!bad, ...);
Taken from NetBSD.
(There is a concern that KASSERT() messages are too long; consume more memory,
and not friendly for small monitors. This have to be considered & revisited
later.)

bounce buffer and before we copy data *from* the bounce buffer. Currently
_bus_dmamap_sync() is a no-op, but keeping it #ifdef'ed out in the wrong
place makes no sense.

TAILQ_FOREACH() isn't safe to use in sched_chooseproc() to iterate
over the run queues because within the loop body we remove the threads
from their run queues and reinsert them elsewhere. As a result, we
end up only draining the first thread of each run queue rather than
all of them.

checksum has to be recalculated before the packet is fragmented
again. Put a missing in6_proto_cksum_out() into pf_refragment6().
This makes run-regress-frag6 and run-regress-frag6-ext pass again.

Also notify upstream when a port finished reseting and when the
connection status changes.
Gets things further along to the point where pipe device transfer
and control methods are required.

The reason being that ext2 structures are little-endian but JBD2 journal
is big-endian. Don't confuse readers by talking about "file system endian".
Some KNF while there.

fixes the rewrite of an IPv6 header of an ICMP6 packet in the payload
of an ICMP6 error packet. Path MTU discovery with ping6 over pf
nat or rdr works again.

the mass killing by init(8) when terminating multi-user operations.

This adds a new assertion macro, KERNEL_ASSERT_LOCKED(), to assert that
kernel_lock is held. In the long process of removing kernel_lock, there will
be a lot (hundreds or thousands) of use of this; virtually almost all functions
in !MP-safe subsystems should have this assertion. Thus this assertion should
have a short, good name.
Not only that "KERNEL_ASSERT_LOCKED" is consistent with other KERNEL_* and
SCHED_ASSERT_LOCKED() macros.

Fixes at least the octeon platform. Found the hardway on my DSR500.
