303a718c5e With ALTQ, it is possible that although the queue was not empty when we
entered the interface start function, no packets were actually dequeued.
Therefore, keep a count of how many packets we really added onto the tx
chain, and initiate a transmit only if the count is non-zero.

1e4cadcb14 Disable use of synchronization early in the boot by the MAC Framework;
for modules linked into the kernel or loaded very early, panics will
result otherwise, as the CV code it calls will panic due to its use
of a mutex before it is initialized.

923a1dc3d1 Add a loader menu option to set hint.atkbd.0.flags=0x1 which allows USB
keyboards to work if no PS/2 keyboard is attached.  The position in the
menu was chosen to avoid moving option 6 (loader prompt).  This should
be a no-op on non-i386/amd64 machines.

0516c8dd4a - When choosing a thread on the run queue, check to see if its nice is
outside of the nice threshold due to a recently awoken thread with a
   lower nice value.  This further reduces the amount of time a positively
   niced thread gets while running in conjunction with a workload that has
   many short sleeps (ie buildworld).

0b762445b9 Move if_handoff() from an inline in if_var.h to a function to if.c
in orden to harden the ABI for 5.x; this will permit us to modify

6bd0c7fd53 - In sched_prio() check to see if the kse is assigned to a runq as the
check for TD_ON_RUNQ() no longer means the thread is really on a run-
   queue.  I suspect this state should be re-evaluated as it must mean
   something else now.  This fixes ULE+KSE+PREEMPTION on UP x86.

4392001125 Move UFS from DEVFS backing to GEOM backing.
This eliminates a bunch of vnode overhead (approx 1-2 % speed
improvement) and gives us more control over the access to the storage
device.

Access counts on the underlying device are not correctly tracked and
therefore it is possible to read-only mount the same disk device multiple
times:
	syv# mount -p
	/dev/md0        /var    ufs rw  2 2
	/dev/ad0        /mnt    ufs ro  1 1
	/dev/ad0        /mnt2   ufs ro  1 1
	/dev/ad0        /mnt3   ufs ro  1 1

Since UFS/FFS is not a synchrousely consistent filesystem (ie: it caches
things in RAM) this is not possible with read-write mounts, and the system
will correctly reject this.

Details:

	Add a geom consumer and a bufobj pointer to ufsmount.

	Eliminate the vnode argument from softdep_disk_prewrite().
	Pick the vnode out of bp->b_vp for now.  Eventually we
	should find it through bp->b_bufobj->b_private.

	In the mountcode, use g_vfs_open() once we have used
	VOP_ACCESS() to check permissions.

	When upgrading and downgrading between r/o and r/w do the
	right thing with GEOM access counts.  Remove all the
	workarounds for not being able to do this with VOP_OPEN().

	If we are the root mount, drop the exclusive access count
	until we upgrade to r/w.  This allows fsck of the root
	filesystem and the MNT_RELOAD to work correctly.

	Set bo_private to the GEOM consumer on the device bufobj.

	Change the ffs_ops->strategy function to call g_vfs_strategy()

	In ufs_strategy() directly call the strategy on the disk
	bufobj.  Same in rawread.

	In ffs_fsync() we will no longer see VCHR device nodes, so
	remove code which synced the filesystem mounted on it, in
	case we came there.  I'm not sure this code made sense in
	the first place since we would have taken the specfs route
	on such a vnode.

	Redo the highly bogus readblock() function in the snapshot
	code to something slightly less bogus: Constructing an uio
	and using physio was really quite a detour.  Instead just
	fill in a bio and ship it down.

4d13ab3da2 Add GEOM class "VFS" for filesystems and other buffer cache users

e1f355fe4e Give the bufobj a private __bo_vnode for now to keep the syncer floating [1]
At some point later the syncer will unlearn about vnodes and the filesystems
method called by the syncer will know enough about what's in bo_private to
do the right thing.
