f2fs: Use bio_for_each_folio_all() in __has_merged_page()

Iterate over each folio rather than each page.  Convert
f2fs_compress_control_page() to f2fs_compress_control_folio() since
this is the only caller.  Removes a reference to page->mapping which
is going away soon as well as calls to fscrypt_is_bounce_page() and
fscrypt_pagecache_page().

f2fs: Use F2FS_P_SB() in f2fs_is_compressed_page()

Remove a reference to page->mapping which is going away soon.

f2fs: Introduce fio_inode()

This helper returns the inode associated with the f2fs_io_info.  That's a
relatively common thing to want, mildly awkward to get and provides one
place to change if we decide to record it directly, or change fio->page
to fio->folio.

f2fs: Use a folio in f2fs_write_raw_pages()

Convert each page in rpages to a folio before operating on it.  Replaces
eight calls to compound_head() with one and removes a reference to
page->mapping which is going away soon.

f2fs: Use a folio in f2fs_compress_free_page()

niu: Create struct niu_page

The map_page() call returns a u64, so using page->private or page->index
to store the result from that will truncate it on 32-bit systems.
Additionally, the next pointer is stored in page->mapping and we're
trying to remove references to page->mapping.  So define a
driver-private struct which overlays struct page and lets us store the
64-bit result of map_page.  Gets rid of the niu_next_page() macro;
we can use the much more natural page->next instead.

vboxsf: Convert to writepages

If we add a migrate_folio operation, we can convert the writepage
operation to writepages.  Further, this lets us optimise by using
the same write handle for multiple folios.  The large folio support here
is illusory; we would need to kmap each page in turn for proper support.
But we do remove a few hidden calls to compound_head().

mm: Rename page->index to page->__folio_index

All users of page->index have been converted to not refer to it any
more.  Prevent new users from appearing (or at least make them
easy to grep for).

intel_th: avoid using deprecated page->mapping, index fields

The struct page->mapping, index fields are deprecated and soon to be only
available as part of a folio.

It is likely the intel_th code which sets page->mapping, index is was
implemented out of concern that some aspect of the page fault logic may
encounter unexpected problems should they not.

However, the appropriate interface for inserting kernel-allocated memory is
vm_insert_page() in a VM_MIXEDMAP. By using the helper function
vmf_insert_mixed() we can do this with minimal churn in the existing fault
handler.

By doing so, we bypass the remainder of the faulting logic. The pages are
still pinned so there is no possibility of anything unexpected being done
with the pages once established.

It would also be reasonable to pre-map everything on fault, however to
minimise churn we retain the fault handler.

We also eliminate all code which clears page->mapping on teardown as this
has now become unnecessary.

The MSU code relies on faulting to function correctly, so is by definition
dependent on CONFIG_MMU. We avoid spurious reports about compilation
failure for unsupported platforms by making this requirement explicit in
Kconfig as part of this change too.
