[PATCH v2 6/6] mm: Print hashed address of struct page

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

The actual address of the struct page isn't particularly helpful,
while the hashed address helps match with other messages elsewhere.
Add the PFN that the page refers to in order to help diagnose problems
where the page is improperly aligned for the purpose.
