Patch series "Use folio APIs in procfs". We're down to very few users of the PageFoo macros, with proc being a major user. After this patchset and another patchset I have for khugepaged, we can get rid of PageActive, PageReadahead and PageSwapBacked. This patchset has the usual advantages in its own right of removing hidden calls to compound_head(). We have the page table lock, so the mapcount & refcount are stable and there can't be any races with folios suddenly becoming tail pages. This patch (of 4): Replaces six calls to compound_head() with one. Shrinks the function from 5054 bytes to 1756 bytes in an allmodconfig build.
