No, I wouldn't re-base on that tree.  If/when Paul updates the selinux
next branch (which should be what your patches are relative to), then I
will re-base my patches on his branch and re-submit the first few
patches to see if we can get those merged now since they don't change
SELinux behavior or interfaces.  That will take care of removing direct
references to the policydb, sidtab, and class/perm mapping among other
things.
