Revert "mm/hmm: fix header file if/else/endif maze"
This reverts commit 25df8b83e867dcfb660123e9589ebf6f094fcdd3 which is
commit b28b08de436a638c82d0cf3dcdbdbad055baf1fc upstream.
There are still build errors with this patch applied, and the upstream
patches do not seem to apply anymore, so reverting this patch seems like
the best thing to do at this point in time.
