Subject: [PATCH v9 5/8] arm64: Move hugetlb related definitions out of
 pgtable.h to page-defs.h

From: Alexander Duyck <alexander.h.duyck@...ux.intel.com>

Move the static definition for things such as HUGETLB_PAGE_ORDER out of
asm/pgtable.h and place it in page-defs.h. By doing this the includes
become much easier to deal with as currently arm64 is the only architecture
that didn't include this definition in the asm/page.h file or a file
included by it.

It also makes logical sense as PAGE_SHIFT was already defined in
page-defs.h so now we also have HPAGE_SHIFT defined there as well.
