The description of VM_KMEM_SIZE_SCALE is roughly as hand-wavy as my

new clang 6.0.0 -Wtautological-constant-compare warning to the WARNS <=

MD_READONLY flag for the md device automatically instantiated during
kernel init for an mdroot filesystem.
Note that there is specifically and by design no tunable or sysctl
control over this feature. Without this option, you already have control
over whether the mdroot fs is writeable using vfs.root.mountfrom.options
from loader(8), the root_rw_mount rcvar, and by using "mount -u[rw] /"
or equivelent on the fly. This option is being added to provide a way
to make the mdroot fs truly immutable before userland code begins running.

Several checks assume .CURDIR is resolved, such as for determining RELDIR from
SRCTOP/.CURDIR. If -C is used then the path is no longer resolved like it was
before which is problematic for symlinked source trees. A similar change was
also made to ports post bmake-20170301.
This fixes 'make -C <symlinked path> buildworld' using the wrong OBJDIR.

This will cause an error if the wanted OBJDIR is not writable. Previously it
would cause the files to generate to the source tree. This was too obscure and
things like buildworld really expect a proper OBJDIR layout.

This change adds an implementation of a sysent for running CloudABI
armv6 and armv7 binaries on FreeBSD/arm64. It is a somewhat literal copy
of the armv6 version, except that it's been patched up to use the proper
registers.
Just like for cloudabi32.ko on FreeBSD/amd64, we make use of a vDSO that
automatically pads system call parameters to 64-bit value. These are
stored in a buffer on the stack, meaning we need to use copyin() and
copyout() unconditionally.
This warning checks whether a constant is out of range of the integer
type. An example is `comparison of 'u_int' > 4294967295 is always false`
and in this case the warning makes sense.
However, when the type is a typedef that can be either 64 or 32 bits the
if condition is only tautological in some configurations so this should
not be a warning that fails the build.

Add missing support for specifying I/O control flags during core reset,
and resolve a number of siba(4)-specific reset issues:
- Add missing check for target reject flags in siba_is_hw_suspended().
- Remove incorrect wait on SIBA_TMH_BUSY when modifying any target state
register; this should only be done when waiting for initiated
transactions to clear.
- Add missing wait on SIBA_IM_BY when asserting SIBA_IM_RJ.
- Overwrite any previously set SIBA_TML_REJ flag when bringing the core
out of reset. This fixes a lockup that occured when we brought up a core
(after reboot) that had previously been placed into RESET by siba_bwn(4).

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Commit these apart because compile testing doesn't guarantee I didn't made
some nasty mistake. No functional change intended.
AHCI emulation is useful for testing scenarios closer to the real

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
This also makes it so that top-level build targets do not immediately create
the OBJDIR. Only sub-make targets will do so. This avoids creating object
directories for targets like 'make check-old' or creating unneeded
MACHINE.MACHINE_ARCH directories during 'make tinderbox'.
