The patch was posted in mailing list at Thu 6/16/2011.

cd445195dd cleanup configure options. All paging related stuff is now automatically set/unset according to cpu-level option.
Related configure options (--enable-pae, --enable-mtrr, --enable-global-pages, --enable-large-pages) are deprecated.
Less configure options - less configure problems :)
