of trying to directly create the snapshot itself. This change allows
users logged into the system as operator to run live dumps.
Note that dump no longer tries to create the snapshot in the root of
the filesystem, but rather in a .snap directory in the root of the
filesystem. The reason is that the operator is usually not permitted
to write into the root of the filesystem. The newfs command and
background fsck have both been modified to create a .snap directory
in the root of the filesystem, but if neither of these have been run,
then the .snap directory must be created manually by the superuser
before a live dump can be run. The .snap directory should be owned
by user root and group operator and set to mode 770.

cylinder groups have been created to show the operation has finished.

- Move the sf_buf API to its own header file; make struct sf_buf's
definition machine dependent. In this commit, we remove an
unnecessary field from struct sf_buf on the alpha, amd64, and ia64.
Ultimately, we may eliminate struct sf_buf on those architecures
except as an opaque pointer that references a vm page.

critical libraries from /usr/lib to /lib. If you don't feel comfortable
with dynamically linked binaries in your root partition, now is the
time to define NO_DYNAMICROOT in your make.conf.

opt_ddb.h. These changes expand green's work of including
opt_global.h to prefer opt files in the kernel directory. Further
refinement might be needed, but I think this is good.
Note: While this is a step on the path to moving the meta information
about modules into the config files, it doesn't actually do that. It
just pulls in the opt files in a way that allows one to build
'generic' modules outside the tree.
disposing fifo resources in fifo_cleanup() instead using of
"vp->v_usecount == 1". There may be other references to the vnode, for
instance by nullfs, at the time fifo_open() or fifo_close() is called,
which could cause a resource leak.
Don't bother grabbing the vnode interlock in fifo_cleanup() since it no
longer accesses v_usecount.

this to be less chatty, disable it so people can boot. The badness of
the spamage is worse than the badness that it reports :-(. Once the
underlying problems have been fixed, it can be reenabled.

* Use both _CST and the FADT to detect Cx states.
* Use both _PTC and P_CNT for controlling throttling.
* Add a notify handler to detect changes in _CST and _PSS
* Call the _INI function for each processor if present. This will be
done by ACPI-CA in the future.
* Fix a bug on SMP systems where CPUs will attach multiple times if the

kses from the run queues. Also, on SMP, we track the transferable
count here. Threads are transferable only as long as they are on the
run queue.
- Previously, we adjusted our load balancing based on the transferable count
minus the number of actual cpus. This was done to account for the threads
which were likely to be running. All of this logic is simpler now that
transferable accounts for only those threads which can actually be taken.
Updated various places in sched_add() and kseq_balance() to account for
this.
- Rename kseq_{add,rem} to kseq_load_{add,rem} to reflect what they're
really doing. The load is accounted for seperately from the runq because
the load is accounted for even as the thread is running.
- Fix a bug in sched_class() where we weren't properly using the PRI_BASE()
version of the kg_pri_class.
- Add a large comment that describes the impact of a seemingly simple
conditional in sched_add().
- Also in sched_add() check the transferable count and KSE_CAN_MIGRATE()
prior to checking kseq_idle. This reduces the frequency of access for
kseq_idle which is a shared resource.
