For PR kern/38537:

- Make MULTIPROCESSOR mandatory on i386.

Installation changes:

- Update installation section of release notes to match reality.
- Rename INSTALL to INSTALL_FLOPPY, retire INSTALL_LARGE.
- Build INSTALL kernel from GENERIC, like on amd64.
- Update boot menu to allow disabling ACPI and/or SMP.
- Remove GENERIC.NOACPI from the installed kernel list.
- TODO: install default boot.cfg in etc.tgz.
- TODO: possibly enable PCI fixup stuff at runtime if ACPI is disabled.

Build changes:

- No longer build ALL, it's for verification, is slow to build and the
build process is already crippled by the number of kernels built.
- No longer build GENERIC.NOACPI.

branches: 1.24.8; 1.24.10;
Remove GENERIC_LAPTOP and INSTALL_LAPTOP. To compensate, switch
bootfloppy-big to actually use INSTALL_LARGE (with ACPI) and 5 floppies.

branches: 1.23.10;
It's "its."

Pad all floppy images to the floppy size.
Requested by Jason Thorpe in [port-i386/23785]

Consistently use "netbsd-XXXXX" instead of "netbsd.XXXXX".

Merge kernel-ramdisk & kernel-rescue into instkernel, now that
../../common/Makefile.mdset supports building multiple copies of the
same kernel (as long as they're to separate filenames).
Now there's no need to set FLOPPYKERNDIR, as it now defaults to instkernel.

always set FLOPPYMETAFILE if FLOPPYSIZE!=2880

Migrate MI-shareable stuff to distrib/common/Makefile.tarfloppy.

- Convert to using distrib/common/buildfloppies.sh, which can build both
single and multi-volume floppies in better fashion that the crufty
shell commands in the various Makefiles.
- Move fdset* -> bootfloppy*, as that's more consistent

Yet Another Cleanup:
- factor more stuff into common/Makefile.*
- use NDWO makefile layout
- don't always rebuild bootfloppy-* and fdset-* stuff. (mmm, dependencies)
- add .WAIT sync in top level Makefile

Use ${PRINTOBJDIR}.

since we have ${TOP}, use it...

Major overhaul, to enable unprivileged (cross) building, removing the
requirement to build as root on a system with vnconfig.


Use ${KERNSRCDIR} and ${_SRC_TOP_} where appropriate

Remove now-obsolete:
list2sh.awk runlist.sh bootfloppy-common/list

Bootfloppy-*/Makefile: don't need to set DISKTYPE or BLOCK8K any more

Rename bootfloppy-common/Makefile.inc to common/Makefile.bootfloppy
and fdset-common/Makefile.inc to common/Makefile.fdset
This uses makefs instead of vnconfig and disklabel, thus removing the
need for root privileges to build these floppies..

Add common/Makefile.ramdisk, to simplify ramdisk-*/Makefile.
Uses shared ${_SRC_TOP_}/distrib/common/Makefile.crunch and
${_SRC_TOP_}/distrib/common/Makefile.image to even further simply things.

Migrate ramdisk-*/dot.profile to a shared common/dot.profile, which
detects whether it's an install or rescue profile based on the existance
of /sysinst. Remove /dev generation code as init(8) now does that for us.

Migrate common parts of */list to a shared common/list.ramdisk.
Convert ramdisk-*/list to new format used by distrib/common/parselist.awk
Don't bother running pwd_mkdb now that libhack's getpwent parses
/etc/master.passwd instead of /etc/passwd.

Migrate ramdisk-*/mtree.conf to a shared common/mtree.conf, which is now a
new full-path-style specfile.

Remove ramdisk-*/ramdiskbin.conf as it's now automatically generated
from ramdisk-*/list by parselist.awk.

Migrate ramdisk-*/termcap.mini to a shared common/termcap.mini.

Remove unused ramdisk-{small,tiny}/disktab.preinstall.

Use .for loops in kernel-*/Makefile to simply defining mostly-duplicated
targets.

ramdisk-*/Makefile: convert to using common/Makefile.ramdisk

Remove unused ramdisk-*/dot.hdprofile.

revert revs 1.10 (and 1.11); now back to using the ustarfs build framework
from ../bootfloppy-common/Makefile.inc like the other boot floppies.
it wasn't ustarfs that was broken, it was the broken PAD=yes code in the
latter trashing the last 8k of the kernel...

1. delete all instances of /dev/{r,}vnd0d. Use vnconfig vnd0 and disklabel
vnd0 and let opendisk(3) DTRT.
2. resize some of the images since we've gotten an average of 5K more
with the new toolchain.
3. comment out the rescue disks, since they don't fit anymore.

Now the whole directory compiles and works with the in-tree toolchain,
but does not work still with USETOOLS.

Switch this one back to FFS, at least until ustarfs is fixed. ustarfs seems
to fail for 2.88 images at certain image sizes.

Rearrange bootfloppies. The idea is that "rescue" tools go on the
floppies as long as they fit, but they are the first to be sacrificed
if space is short, and get moved to a seperate rescue floppy.

This means that the default fdset and the 2.88M image have them,
but others (the "small" and "tiny" floppies) do not.

Sysinst is also back on the "tiny" image, and tested to be working
within 4M.

If the PAD variable is defined, pad the floppy image to its maximum size.
Use this in bootfloppy-big. mkisofs likes to have images fullsize nowadays.
Also, insert a file called "USTAR.volsize.<blocksize_in_octal>" if the
size of the ustar image is not the 1.44M default. This stops bootfloppy-big
from asking for a second diskette.

branches: 1.7.4;
Need BLOCK8K now.

Merge latest build system changes, and use the kernels built in ramdisk-kernel.

use bsd.kernobj.mk to tell us KERNOBJDIR for compiled kernels.

allow to set location of INSTALL kernel from command line so that
bootfloppies can be built with r/o /usr/src or with other kernels

Let's call this image boot-big.fs.

Typo correction.

bootfloppy-big/Makefile creates 2.88M diskette image suitable for CD-ROM boot.
(Depends on new disktab from etc/etc.i386/.)
Don't descend into bootfloppy and bootfloppy-small since these now overflow,
now do ramdisk, fdset, bootfloppy-big, and bootfloppy-tiny.
