Subject: Split kernel into kernel-core and kernel-drivers subpackages

This creates kernel-core and kernel-drivers subpackages.  The kernel package
remains as a meta-package the requires both of the subpackages.  This allows
most installs to continue on as-is with upgrades working.

The contents of the kernel-core and kernel-drivers subpackages are determined
at build time through the filter-modules.sh script.  This script "removes"
pre-defined subsystems and modules and generates a filelist for the %files
section of each subpackage.  The contents of each are per-arch, with arch
override files taken into account.  This allows us to make the split useful
for varying arches.

+# This script filters the modules into the kernel-core and kernel-drivers
+# subpackages.  We list out subsystems/subdirs to prune from the installed
+# module directory.  What is left is put into the kernel-core package.  What is
+# pruned is contained in the kernel-drivers package.
+#
+# This file contains the default subsys/subdirs to prune from all architectures.
+# If an architecture needs to differ, we source a per-arch filter-<arch>.sh file
+# that contains the set of override lists to be used instead.  If a module or
+# subsys should be in kernel-drivers on all arches, please change the defaults
+# listed here.
