bpf(4) are different enough so that the split makes sense -- this is necessary
to make bpf(4) cloneable.

more work in progress to handle these exceptions correctly, and document

directive can select between MI and MD versions of these files. At
the same time, adjust the boot programs to pick exactly what they need,
instead of the 7 or 8 mechanisms previously used.
There will be some fallout from this, but testing it all by myself is a
ridiculously slow process; it will be finished in-tree.
Various developers were very nice and avoided making fun of me when I
was gibbering in the corner..

decide which files must be pulled into the kernel. Also conditionalize
the pulling of those files based on the COMPAT_* options.

been years since it has last been used for that purpose, so name it the
initialization/startup stack.
While there, do not store the initialization stack in cpu_info, and have
secondary_pre_main() return its value so that the bootstrap code does not
need to fetch it from cpu_info.
This might be reconsidered when the startup stacks will be freed after they
are not used anymore, but there are more things to do first.

a single ci_flags bitfield.
Also, set_cpu_number() will no longer set CIF_PRIMARY on the primary processor,
it's up to the initialization code to do this.

- Move the functionality of choosing a process from cpu_switch into
a much simpler function: cpu_switchto. Instead of having the locore
code walk the run queues, let the MI code choose the process we
want to run and only implement the context switching itself in MD
code.
- Let MD context switching run without worrying about spls or locks.
- Instead of having the idle loop implemented with special contexts
in MD code, implement one idle proc for each cpu. make the idle
loop MI with MD hooks.
- Change the proc lists from the old style vax queues to TAILQs.
- Change the sleep queue from vax queues to TAILQs. This makes
wakeup() go from O(n^2) to O(n)
there will be some MD fallout, but it will be fixed shortly.
There's also a few cleanups to be done after this.

kernel builds locally this doesnt change much but over NFS this
cuts about 12% of the build time on my setup (i386).
OK miod@, deraadt@.

cpu_disklabel can go away, since nothing anymore needs to use it; ok miod

block/native label as needed rather than keeping it in cpu_disklabel.
Also a number of assorted minor tweaks to reduce the delta to sparc64

to support hotplug media on most architectures. disklabel setup and
verification done using new helper functions. Disklabels must *always*
have a correct checksum now. Same code paths are used to learn on-disk
location disklabels, to avoid new errors sneaking in. Tested on almost all
cases, testing help from todd, kettenis, krw, otto, dlg, robert, gwk, drahn

look at how doing it in one architecture gets that code copied to the

routines (alpha, vax) prove to be not worth keeping. Move
bounds_check_with_label() into the MI world. Eliminate unreliable and
almost certainly useless checks for overwriting a disklabel.
After discussion with deraadt@

implimentations were simply either missing code, or spacing and such.
setdisklabel() can become MI now.

type of all variables to daddr64_t. this includes the APIs for XXsize()
and XXdump(), all range checks inside bio drivers, internal variables
for disklabel handling, and even uvm's swap offsets. re-read numerous
times by otto, miod, krw, thib to look for errors

accuracy so that the variious disksubr.c's can be compared easier.
setdisklabel() starts taking an int for openmask.
ok krw, and read by quite a few other people

|
for overwriting the disklabel. Reorder some checks so all copies of
bounds_check_with_label do the checks in the same order. Order picked
by using the currently most popular one. Should be no functional
change.

next comes the type handling surrounding these values
