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. It also provides either the default alias or the opted-in
hw_pte_t wrapper.

Stand-alone header file updates are not ideal. Why cannot these changes be
folded in, where hw_pte_t gets used first time ever in the above mentioned
places.

That's correct. This patch should be merged with the 3/9 patch. But that patch
is already too much big as it was generated with the help of Coccinelle. So I
kept it separate.

Do you still think we should merge it as its a special case?

Sorry, I wanted to mention merging this patch and 4/9 patch (instead of 3/9 patch) in
my previous email.
