In r296926 the -P <path> option was added to kbdcontrol, which enables

Keymap header files have historically been generated using the build
host's /usr/sbin/kbdcontrol and using the host's keymap files.
However, that introduces an issue when building a kernel to use vt(4)
on a system using sc(4), or vice versa: kbdcontrol searches for keymap
files in the /usr/share subdirectory appropriate for the host, not the
target.
With this change the build searches both the and sc keymap directories
from the source tree.

The MD allocators were very common, however there were some minor
differencies. These differencies were all consolidated in the MI allocator,
under ifdefs. The defines from machine/vmparam.h turn on features required
for a particular machine. For details look in the comment in sys/sf_buf.h.
As result no MD code left in sys/*/*/vm_machdep.c. Some arches still have
machine/sf_buf.h, which is usually quite small.

When running as a PVH guest, there's no emulated i8254, so we need to

GIANT from VFS. In addition, disconnect also netsmb, which is a base
requirement for SMBFS.
In the while SMBFS regular users can use FUSE interface and smbnetfs
port to work with their SMBFS partitions.
Also, there are ongoing efforts by vendor to support in-kernel smbfs,
so there are good chances that it will get relinked once properly locked.
This is not targeted for MFC.
The 'make depend' rules have to use custom -I paths for the special compat

This option will pull in the couple of files that are shared with dtrace,
but they appear to correctly use the MODULE_VERSION/MODULE_DEPEND rules
so loader should do the right thing, as should kldload.

Keeping both around for the moment allows us to compile NIC drivers
even in an IPv6 only environment without the need to mangle them
