I think this is still broken.  Same problem when I went to configure
ALSA for -mm3-T3.  The configure script gets
CONFIG_HAVE_OLD_REMAP_PAGE_RANGE wrong; I have the new version but
configure fails to detect it.

AFAICT the test in configure is a NOOP and
CONFIG_HAVE_OLD_REMAP_PAGE_RANGE always gets set to 1.
