Mike Kravetz 359f25443a hugetlbfs: move hugepagesz= parsing to arch independent code
Now that architectures provide arch_hugetlb_valid_size(), parsing of
"hugepagesz=" can be done in architecture independent code.  Create a
single routine to handle hugepagesz= parsing and remove all arch specific
routines.  We can also remove the interface hugetlb_bad_size() as this is
no longer used outside arch independent code.

This also provides consistent behavior of hugetlbfs command line options.
The hugepagesz= option should only be specified once for a specific size,
but some architectures allow multiple instances.  This appears to be more
of an oversight when code was added by some architectures to set up ALL
huge pages sizes.
