Peter Grehan 608f97c359 Add support for running as a nested hypervisor under VMWare Fusion, on
systems with VT-x/EPT (e.g. Sandybridge Macbooks). This will most
likely work on VMWare Workstation8/Player4 as well. See the VMWare app
note at:

  http://communities.vmware.com/docs/DOC-8970

Fusion doesn't propagate the PAT MSR auto save-restore entry/exit
control bits. Deal with this by noting that fact and setting up the
PAT MSR to essentially be a no-op - it is init'd to power-on default,
and a software shadow copy maintained.

Since it is treated as a no-op, o/s settings are essentially ignored.
This may not give correct results, but since the hypervisor is running
nested, a number of bets are already off.

On a quad-core/HT-enabled 'MacBook8,2', nested VMs with 1/2/4 vCPUs were
fired up. The more nested vCPUs the worse the performance, unless the VMs
were started up in multiplexed mode where things worked perfectly up to
the limit of 8 vCPUs.

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.
