marcel 54721434df o os_boot_rendez is responsible for clearing the IRR bit by
reading cr.ivr, as well as writing to cr.eoi.
o  use global variables to pass information to os_boot_rendez
   so that it doesn't have to jump through hoops to find it
   out. This avoids traps on the AP without it even being
   initialized. This fixes SMP configurations.
o  Move the probing of the MADT to the end of cpu_startup,
   instead of at the start of cpu_mp_probe. We need to probe
   the MADT for non-SMP configurations as well. This fixes
   uniprocessor configurations.
o  Serialize AP wake-up by waiting for the AP. We need to do
   this since we use global variables to for the AP to use.
   As a side-effect, we can use printf() more easily to see
   what's going on.

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
``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/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 have to build
world before.  More information is available in the handbook.

The sample kernel configuration files reside in the sys/i386/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.
