[PATCH 0/4] Use generic_file_read_iter() in hugetlbfs

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

This set of patches are separated out from Jane's earlier series.

I feel that they represent a reasonable amount of change to send
separately, although I'm going to keep looking at the rest of the sseries
because I actually need it to do a further improvement that I'm working on.

I'm not 100% confident in all of this, so I'd appreciate feedback.
I've run the libhugetlbfs test suite against it and observe no new
failures, but I'm not sure it's thoroughly exercising the read() path,
and I'm absolutely certain it's not exercising the memory-failure paths.

Jane Chu (2):
  filemap: add hwpoison handling to filemap_read()
  hugetlbfs: replace hugetlbfs_read_iter() with generic_file_read_iter()

Matthew Wilcox (Oracle) (2):
  hugetlbfs: Set mapping folio order
  mm: Handle hugetlb correctly in is_page_hwpoison()
