Lawrence Stewart a8d61afdc2 - Introduce the Hhook (Helper Hook) KPI. The KPI is closely modelled on pfil(9),
and in many respects can be thought of as a more generic superset of pfil.
  Hhook provides a way for kernel subsystems to export hook points that Khelp
  modules can hook to provide enhanced or new functionality to the kernel. The
  KPI has been designed to ensure hook points pose no noticeable overhead when
  no hook functions are registered.

- Introduce the Khelp (Kernel Helpers) KPI. Khelp provides a framework for
  managing Khelp modules, which indirectly use the Hhook KPI to register their
  hook functions with hook points of interest within the kernel. Khelp modules
  aim to provide a structured way to dynamically extend the kernel at runtime in
  an ABI preserving manner. Depending on the subsystem providing hook points, a
  Khelp module may be able to associate per-object data for maintaining relevant
  state between hook calls.

- pjd's Object Specific Data (OSD) KPI is used to manage the per-object data
  allocated to Khelp modules. Create a new "OSD_KHELP" OSD type for use by the
  Khelp framework.

- Bump __FreeBSD_version to 900028 to mark the introduction of the new KPIs.

This is the top level of the FreeBSD source directory.  This file
was last revised on:
$FreeBSD$

For copyright information, please see the file COPYRIGHT in this
directory (additional copyright information also exists for some
sources in this tree - please see the specific source directories for
more information).

The Makefile in this directory supports a number of targets for
building components (or all) of the FreeBSD source tree, the most
commonly used one being ``world'', which rebuilds and installs
everything in the FreeBSD system from the source tree except the
kernel, the kernel-modules and the contents of /etc.  The ``world''
target should only be used in cases where the source tree has not
changed from the currently running version.  See:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html
for more information, including setting make(1) variables.

The ``buildkernel'' and ``installkernel'' targets build and install
the kernel and the modules (see below).  Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.

Building a kernel is a somewhat more involved process, documentation
for which can be found at:
   http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html
And in the config(8) man page.
Note: If you want to build and install the kernel with the
``buildkernel'' and ``installkernel'' targets, you might need to build
world before.  More information is available in the handbook.

The sample kernel configuration files reside in the sys/<arch>/conf
sub-directory (assuming that you've installed the kernel sources), the
file named GENERIC being the one used to build your initial installation
kernel.  The file NOTES contains entries and documentation for all possible
devices, not just those commonly used.  It is the successor of the ancient
LINT file, but in contrast to LINT, it is not buildable as a kernel but a
pure reference and documentation file.
