Instead of the old @page and @page_offset pair inside scrub, here we can
directly use the virtual address for a sector.
This has the following benefit:
- Simplified parameters
A single @kaddr will repair @page and @page_offset.
- No more unnecessary kmap/kunmap calls
Since all pages utilized by scrub is allocated by scrub, and no
highmem is allowed, we do not need to do any kmap/kunmap.
And add an ASSERT() inside the new scrub_stripe_get_kaddr() to
catch any unexpected highmem page.

Instead of using a @page + @pg_offset pair inside sector_ptr structure,
use a single physical address instead.
This allows us to grab both the page and offset from a single u64 value.
Although we still need an extra bool value, @has_paddr, to distinguish
if the sector is properly mapped (as the 0 physical address is totally
valid).
This change doesn't change the size of structure sector_ptr, but reduces
the parameters of several functions.
Note: the original idea and patch is from Christoph Hellwig
(https://lore.kernel.org/linux-btrfs/20250409111055.3640328-7-hch@lst.de/)
but the final implementation is different.

Move kmapping the page out of btrfs_check_sector_csum().
This allows using bvec_kmap_local() where suitable and reduces the number
of kmap*() calls in the raid56 code.
This also means btrfs_check_sector_csum() will only accept a properly
kmapped address.

Using physical address has the following advantages:
- All involved callers only need a single pointer
Instead of the old @folio + @offset pair.
- No complex poking into the bio_vec structure
As a bio_vec can be single or multiple paged, grabbing the real page
can be quite complex if the bio_vec is a multi-page one.
Instead bvec_phys() will always give a single physical address, and it
cab be easily converted to a page.

The bio implementation is not something we should really mess around,
and we shouldn't recalculate the pos from the folio over and over.
Instead just track then end of the current bio in logical file offsets
in the btrfs_bio_ctrl, which is much simpler and easier to read.

end_bbio_data_read() checks that each iterated folio fragment is aligned
and justifies that with block drivers advancing the bio. But block
driver only advance bi_iter, while end_bbio_data_read() uses
bio_for_each_folio_all() to iterate the immutable bi_io_vec array that
can't be changed by drivers at all.
Furthermore btrfs has already did the alignment check of the file
offset inside submit_one_sector(), and the size is fixed to fs block
size, there is no need to re-do the alignment check again inside the
endio function.
So just remove the unnecessary alignment check along with the incorrect
comment.

Currently we reject large folios for defrag gracefully, but the
implementation itself is already mostly large folios compatible.
There are several parts of defrag in btrfs:
- Extent map checking
Aka, defrag_collect_targets(), which prepares a list of target ranges
that should be defragged.
This part is completely folio unrelated, thus it doesn't care about
the folio size.
- Target folio preparation
Aka, defrag_prepare_one_folio(), which lock and read (if needed) the
target folio.
Since folio read and lock are already supporting large folios, this
part needs only minor changes.
- Redirty the target range of the folio
This is already done in a way supporting large folios.
So it's pretty straightforward to enable large folios for defrag:
- Do not reject large folios for experimental builds
This affects the large folio check inside defrag_prepare_one_folio().
- Wait for ordered extents of the whole folio in
defrag_prepare_one_folio()
- Lock the whole extent range for all involved folios in
defrag_one_range()
- Allow the folios[] array to be partially empty
Since we can have large folios, folios[] will not always be full.
This affects:
* How to allocate folios in defrag_one_range()
Now we cannot use page index, but use the end position of the folio
as an iterator.
* How to free the folios[] array
If we hit an empty slot, it means we have large folios and already
hit the end of the array.
* How to mark the range dirty
Instead of use page index directly, we have to go through each
folio, and check if the folio covers the defrag target inside
defrag_one_locked_target().

All compression algorithms inside btrfs are not supporting large folios
due to the following points:
- btrfs_calc_input_length() is assuming page sized folio
- kmap_local_folio() usages are using offset_in_page()
Prepare them to support large data folios by:
- Add a folio parameter to btrfs_calc_input_length()
And use that folio parameter to calculate the correct length.
Since we're here, also add extra ASSERT()s to make sure the parameter
@cur is inside the folio range.
This affects only zlib and zstd. Lzo compresses at most one block at a
time, thus not affected.
- Use offset_in_folio() to calculate the kmap_local_folio() offset
This affects all 3 algorithms.

The function needs only to return true or false, so there's no need to
return an integer. Currently it returns 0 when a range with the given
bits is set and 1 when not found, which is a bit counter intuitive too.
So change the function to return a bool instead, returning true when a
range is found and false otherwise. Update the function's documentation
to mention the return value too.

These functions aren't used outside extent-io-tree.c, but yet one of them
(extent_io_tree_to_inode()) is unnecessarily exported in the header.
Furthermore their single use is in a pattern like this:
if (is_inode_io_tree(tree))
foo(extent_io_tree_to_inode(tree), ...);
So we're effectively unnecessarily adding more indirection, checking
twice if tree->owner == IO_TREE_INODE_IO before getting the inode and
doing a non-inline function call to get tree->inode.
Simplify this by removing these helper functions and instead doing
thing like this:
if (tree->owner == IO_TREE_INODE_IO)
foo(tree->inode, ...);

The page size is 4K, and the fs block size is also 4K.

And we have a large folio sized 8K at file offset 16K.

Inside functions unlock_delalloc_folio() and lock_delalloc_folios(), we
have the following early exits:
if (index == locked_folio->index && end_index == index)
return;
This allows us to exit early if the range is inside the same locked
folio.
However the current check relies on page sized folios, if we have a large
folio that contains @index but not at @index, then the early exit will
no longer trigger.
Furthermore without the above early check, the existing code can handle it
well, as both __process_folios_contig() and lock_delalloc_folios() will
skip any folio page lock/unlock if it's on the locked folio.
Here we remove the early exits and let the existing code handle the
same index case, to make the code a little simpler.
