ppc/hugetlbfs: Replace ACCESS_ONCE with READ_ONCE
commit da1a288d8562739aa8ba0273d4fb6b73b856c0d3 upstream.
ACCESS_ONCE does not work reliably on non-scalar types. For
example gcc 4.6 and 4.7 might remove the volatile tag for such
accesses during the SRA (scalar replacement of aggregates) step
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58145)
Change the ppc/hugetlbfs code to replace ACCESS_ONCE with READ_ONCE.
