svn commit: r214629 - in head: include sys/conf sys/x86/include

[John Baldwin]

Author: jhb
Date: Mon Nov  1 17:34:04 2010
New Revision: 214629
URL: http://svn.freebsd.org/changeset/base/214629

Log:
  Add an x86/include directory to the kernel to hold headers that are common
  to amd64, i386, and pc98.  The headers are installed to /usr/include/x86
  during an installworld, and an 'x86' symlink is created for kernel builds
  similar to 'machine' so that the headers can be included as <x86/foo.h>.
