Marcel Moolenaar fae3c3b7eb Rough implement of makecontext() needed to support libthr.
o  Up to 8 arguments are allowed. This is the number of arguments
   passed in registers. Subsequent registers are passed on the stack.
   Trying to deal with this is not easy in C and likely forces us to
   use assembly code. Let's avoid that for now. There's no indication
   that more than 8 arguments is a strong requirement (Linux also has
   an 8 argument limit).
o  We expect that the stack base is 16-byte aligned and the stack
   size is a multiple of 16-byte. We bomb out if this is not the case.
   We probably want to be less strict by enforcing it ourselves. For
   now it's better to not hide gross alignment bogons by silently
   correcting it.

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/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.
