Benjamin Herrenschmidt 0ef89d25d3 mm/hugetlb: don't crash when HPAGE_SHIFT is 0 
Some platform decide whether they support huge pages at boot time.  On
these, such as powerpc, HPAGE_SHIFT is a variable, not a constant, and is
set to 0 when there is no such support.

The patches to introduce multiple huge pages support broke that causing
the kernel to crash at boot time on machines such as POWER3 which lack
support for multiple page sizes.
