Matthew Wilcox (Oracle) dee3d0bef2 proc: rewrite stable_page_flags()
Reduce the usage of PageFlag tests and reduce the number of
compound_head() calls.

For multi-page folios, we'll now show all pages as having the flags that
apply to them, e.g.  if it's dirty, all pages will have the dirty flag set
instead of just the head page.  The mapped flag is still per page, as is
the hwpoison flag.
