Paolo Bonzini a42150f1c9 mm: provide a saner PTE walking API for modules
commit 9fd6dad1261a541b3f5fa7dc5b152222306e6702 upstream.

Currently, the follow_pfn function is exported for modules but
follow_pte is not.  However, follow_pfn is very easy to misuse,
because it does not provide protections (so most of its callers
assume the page is writable!) and because it returns after having
already unlocked the page table lock.

Provide instead a simplified version of follow_pte that does
not have the pmdpp and range arguments.  The older version
survives as follow_invalidate_pte() for use by fs/dax.c.
