syscall) confirm the stack register points at MAP_STACK memory, otherwise
SIGSEGV is delivered. sigaltstack() and pthread_attr_setstack() are modified
to create a MAP_STACK sub-region which satisfies alignment requirements.
Observe that MAP_STACK can only be set/cleared by mmap(), which zeroes the
contents of the region -- there is no mprotect() equivalent operation, so
there is no MAP_STACK-adding gadget.
This opportunistic software-emulation of a stack protection bit makes
stack-pivot operations during ROPchain fragile (kind of like removing a
tool from the toolbox).

The account flag `ASU' will no longer be set but that makes suser()
mpsafe since it no longer mess with a per-process field.

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.

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.

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.

Same thought from kettenis@, ok krw@ phessler@ millert@

Add sysctl kern.allowkmem (default 0) which controls the ability to open
/dev/mem or /dev/kmem at securelevel > 0. Over 15 years we converted 99%
of utilities in the tree to operate on sysctl-nodes (either by themselves
or via code hiding in the guts of -lkvm).
pstat -d and -v & procmap are affected and continued use of them will
require kern.allowkmem=1 in /etc/sysctl.conf. acpidump (and it's
buddy sendbug) are affected, but we'll work out a solution soon.
There will be some impact in ports.
