This series handle configs where hugepage support is not enabled by default. Also, we update some of the information messages to make sure we use PAGE_SIZE instead of SZ_4K. We now store page size and struct page size in pfn_sb and do extra check before enabling namespace. There also an endianness fix. The patch series is on top of subsection v10 patchset http://lore.kernel.org/linux-mm/156092349300.979959.17603710711957735135.stgit@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Changes from V3: * Dropped the change related PFN_MIN_VERSION * for pfn_sb minor version < 4, we default page_size to PAGE_SIZE instead of SZ_4k.
