When we switched to big endian page table, we never updated
the hugepd format such that it can work for both big endian and
little endian config. This patch series update hugepd format
such that it is looked at as __be64 value in big endian page
table config.
This patch also switch hugepd_t.pd from signed long to unsigned long.
I did update the FSL hugepd_ok check to check for the top bit instead
of checking > 0.
