at runtime and to support distributing additional kernels:
o remove kernel from the base tarball
o add new kernel tarballs
o build + package both SMP and GENERIC kernels when an <arch>/conf/SMP
config file is present
o add sysinstall support for multiple kernels
o update sysinstall to probe for the number of cpus on a system
and auto-select smp/up kernel accordingly
o add a post-kernels install hook to fixup /boot/kernel
o add -ldevinfo to boot crunch for sysinstall's cpu probing logic
Notes:
1. On HEAD this code is not currently used because GENERIC kernels
include SMP. This work is mainly intended for RELENG_6 where the
GENERIC kernel is UP. If HEAD changes to match then just enable
WITH_SMP in sysinstall/Makefile.
2. The cpu probing support is done with acpi and MPTable; this means
some systems will require work for auto-detection to work.
3. The handling of /boot/kernel may need to be revisited; for now
we rename one kernel at the last moment (SMP if installed, otherwise
GENERIC). There are other, possibly better, approaches.
Lots of help from ru, emaste, scottl, and jhb.
boot.flp in 5.3 and later is not self-contained and thus not suitable for
CD booting. /boot/cdboot is now the only way to boot the install CDs.

Death to the stripped down BOOTMFS kernel for boot floppies and all the
cruft that goes along with it.
that causes the bootable ISO images to be created using the floppy
emulation (the old method) as opposed to the new "cdboot" method.
Only copy boot.flp to the 2nd CD-ROM if this variable is defined.

Also make sure bsdlabel(8) (along with the disklabel(8) compat
link) still appear on the fixit floppies of platforms that use
it natively (alpha, i386, and pc98).

If we have no UFS_ACL kernel, users who already uses UFS1/2 attributes
get confused since no access control is performed for an update install.
Still, pc98 and alpha doesn't have UFS_ACL since I don't know about them.
Nyan-san, if kern.flp on tatsu has enough spaces (4k or more spaces),
please back UFS_ACL for pc98 also.

aacp is a passthrough driver for aac, but it seems that aac kernel
module has a feature provided by aacp; so it can be removed safely.
_KPOSIX_PRIORITY_SCHEDULING provides P1003.1B realtime extension.
However, in an installation phase, it seems that it helps a little
for us, so we can remove this option from a kernel for floppy installation.
I know _KPOSIX_PRIORITY_SCHEDULING option is defined in other architecture.
However, I don't touch them at this time; I can't test it.
Anyway here's result.
