[PATCH RFC 02/11] mm: make hw_pte_t visible to generic PTE interfaces

[Muhammad Usama Anjum]

Later conversions use hw_pte_t in page-table checking, generic page-table
helpers, and vmalloc interfaces. Include linux/pgtable_types.h from the
headers that declare those interfaces before changing their types.

For vmalloc.h, replace the direct asm/page.h include with
linux/pgtable_types.h. The latter includes asm/page.h, so pgprot_t remains
available.
