[0/7] More filesystem folio conversions for 6.6

Message

Remove the only spots in affs which actually use a struct page; there
are a few places where one is mentioned, but it's part of the interface.

The rest of this is removing the remaining calls to set_bh_page(),
and then removing the function before any new users show up.

Matthew Wilcox (Oracle) (7):
  highmem: Add memcpy_to_folio() and memcpy_from_folio()
  affs: Convert affs_symlink_read_folio() to use the folio
  affs: Convert data read and write to use folios
  migrate: Use folio_set_bh() instead of set_bh_page()
  ntfs3: Convert ntfs_get_block_vbo() to use a folio
  jbd2: Use a folio in jbd2_journal_write_metadata_buffer()
  buffer: Remove set_bh_page()
