[PATCH 09/11] mm: Reimplement folio_is_device_coherent()

["Matthew Wilcox (Oracle)" <willy@infradead.org>]

For callers of folio_is_device_coherent(), we save a folio->page->folio
conversion.  Callers of is_device_coherent_page() simply move the
conversion of page->folio from the implementation of page_pgmap()
to is_device_coherent_page().
