Re: [PATCH v2 2/4] 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.

This could change the error messages for a wrong setup on archs, but I
guess it's not a big deal, assuming even to capture error people will
majorly still look for error lines in general..
