[PATCH v1 0/4] mm: folio_pte_batch() improvements

[David Hildenbrand]

Ever since we added folio_pte_batch() for fork() + munmap() purposes,
a lot more users appeared (and more are being proposed), and more
functionality was added.

Most of the users only need basic functionality, and could benefit from
a non-inlined version.

So let's clean up folio_pte_batch() and split it into a basic
folio_pte_batch() (no flags) and a more advanced folio_pte_batch_ext().
Using either variant will now look much cleaner.

This series will likely conflict with some changes in some
(old+new) folio_pte_batch() users, but conflicts should be trivial to
resolve.

Tested on x86-64. Cross-compile tested.
