Dominik Dingel 41318bfe2a revert "s390/mm: make hugepages_supported a boot time decision" 
Heiko noticed that the current check for hugepage support on s390 is a
little bit too harsh as systems which do not support will crash.

The reason is that pageblock_order can now get negative when we set
HPAGE_SHIFT to 0.  To avoid all this and to avoid opening another can of
worms with enabling HUGETLB_PAGE_SIZE_VARIABLE I think it would be best
to simply allow architectures to define their own hugepages_supported().

Revert bea41197ea ("s390/mm: make hugepages_supported a boot time
decision") in preparation.
