for blocks re-fetchable from the filesystem. However at reboot time,
filesystems are unmounted, and since processes lack backing store they
are killed. Since the scheduler is still running, in some cases init is
killed... which drops us to ddb [noted by bluhm]. Solution is to convert
filesystems to read-only [proposed by kettenis]. The tale follows:
sys_reboot() should pass proc * to MD boot() to vfs_shutdown() which
completes current IO with vfs_busy VB_WRITE|VB_WAIT, then calls VFS_MOUNT()
with MNT_UPDATE | MNT_RDONLY, soon teaching us that *fs_mount() calls a
copyin() late... so store the sizes in vfsconflist[] and move the copyin()
to sys_mount()... and notice nfs_mount copyin() is size-variant, so kill
legacy struct nfs_args3. Next we learn ffs_mount()'s MNT_UPDATE code is
sharp and rusty especially wrt softdep, so fix some bugs adn add
~MNT_SOFTDEP to the downgrade. Some vnodes need a little more help,
so tie them to &dead_vnops.
ffs_mount calling DIOCCACHESYNC is causing a bit of grief still but
this issue is seperate and will be dealt with in time.

end of rc we call reorder_kernel which creates a /obsd hard link to
the same kernel.
In the past obsd was only created when doing a manual make install in
the kernel sources.
There is no need for two backup hard links during boot, rearange the
kernel Makefiles to restore previous behaviour and thus stopping
reorder_kernel from scribbling over /obsd.
Makes muscle memory of some kernel developers work again: /obsd can
serve as a known good kernel; and there was much rejoycing...
Discussed at length with benno, rpe, phessler and tb at
p2k17.
Seems like a good idea to deraadt.

the kernel makefiles was removed which lead to C files not being re-
compiled when a dependency changed. This can lead to panics in odd
places and generally a broken system.

clang optimizes better for size with -Oz so use that as a default to avoid
overflowing the ramdisk floppies. gcc now accepts -Oz as an alias for -Os.

below /sys. This restores the behavior prior to the KARL implementation.

without src and comp work. That is what we've designed for, but since
we always have src and comp on our systems it is so easy to slide...

architectures we must also link against a gapdummy.o to repair the ABI
of the resulting .o file. Woe is me.
Also repair install: target to update the linkkit & hash when a kernel
is installed.

run so that this locore0.o is always at the start of the executable.
But randomize the link order of all other .o files in the kernel, so
that their exec/rodata/data/bss segments land all over the place.
I haven't worked on the unmap/smashing of the startup code yet.

Prying eyes cannot look at the kernels in the compile directory.

this is so drivers can advertise that they can handle 64 dma addresses
to the platform. it may choose to handle dmamaps differently based
on this flag.

the environment, 'make cleandir' does not descend into kernel build
directories. Thus, kernel object files survive 'make build' on slower
architectures.
WARNING:
If you set this variable, you run the risk of breaking 'make release':
Be sure to run 'make cleandir' from /sys/arch/$(machine)/compile before
doing 'make release'. This issue will be addressed shortly.

This will allow us to extract type informations from DWARF2 sections. It
also makes developer life easier as debug information are now included in
every object.
Resulting kernels will be stripped using strip(1) instead of ld(1).
Kernel build time increases by approximately 10%. However it is still
possible to disable this by defining DEBUG="".

- Remove the 'lint' target. lint has been removed with OpenBSD 5.2.
- Remove the 'tags' target. It does nothing of value.
- Replace 'clean::' with 'clean:', as requested by espie and millert,
and remove files from the 'clean' target, that are never generated.
- Don't create a file called 'depend' in 'make depend', but just do
nothing instead.

defer their creation to later, so that they are owned by BUILDUSER.
This eliminates the last root-owned files in obj/ from 'make build'.
In addition, place a MACHINE == hppa test in hppa/stand/Makefile.inc
to avoid creating bogus symlinks on all other archs.

1) Replace '.elif !exists(${OBJDIR}/Makefile)' with just '.else'. espie
pointed out, that if the file existed, make wouldn't be reading this
file, so the check is superflous. Less clutter.
2) Unconditionally define the 'clean' and 'cleandir' targets, also when
obj doesn't exist. This changes the behaviour of 'make clean' to be
successful (doing nothing) without obj@ or obj/.

if srctree is not rooted at /usr/src]. As a result, stock GENERIC & RAMDISK
kernels are commited to the tree, to ensure the src tree can be "readonly"
during builds, with all writes occuring inside the obj space. config -b
options are handled by ../Makefile.inc. The canonical new way to configure
one of these kernels is:
% cd /sys/arch/amd64/compile/GENERIC.MP
% doas make obj
% make config
% make
% doas cp obj/bsd /bsd
The build infrastructure will use this new mechanism in a de-escalation
way using BUILDUSER.
Much help from natano and tb.
