Note: this is a fixed version that was previously reverted as
e01a83e1 ("Revert "btrfs: zstd: fix and simplify the inline extent
decompression""), with fixed parameters to memzero_page().

[BUG]
If we have a filesystem with 4k sectorsize, and an inlined compressed
extent created like this:

	item 4 key (257 INODE_ITEM 0) itemoff 15863 itemsize 160
		generation 8 transid 8 size 4096 nbytes 4096
		block group 0 mode 100600 links 1 uid 0 gid 0 rdev 0
		sequence 1 flags 0x0(none)
	item 5 key (257 INODE_REF 256) itemoff 15839 itemsize 24
		index 2 namelen 14 name: source_inlined
	item 6 key (257 EXTENT_DATA 0) itemoff 15770 itemsize 69
		generation 8 type 0 (inline)
		inline extent data size 48 ram_bytes 4096 compression 3 (zstd)

Then trying to reflink that extent in an aarch64 system with 64K page
size, the reflink would just fail:

  # xfs_io -f -c "reflink $mnt/source_inlined 0 60k 4k" $mnt/dest
  XFS_IOC_CLONE_RANGE: Input/output error

[CAUSE]
In zstd_decompress(), we didn't treat @start_byte as just a page offset,
but also use it as an indicator on whether we should error out, without
any proper explanation (this is copied from other decompression code).

In reality, for subpage cases, although @start_byte can be non-zero,
we should never switch input/output buffer nor error out, since the whole
input/output buffer should never exceed one sector, thus we should not
need to do any buffer switch.

Thus the current code using @start_byte as a condition to switch
input/output buffer or finish the decompression is completely incorrect.

[FIX]
The fix involves several modification:

- Rename @start_byte to @dest_pgoff to properly express its meaning

- Use @sectorsize other than PAGE_SIZE to properly initialize the
  output buffer size

- Use correct destination offset inside the destination page

- Simplify the main loop
  Since the input/output buffer should never switch, we only need one
  zstd_decompress_stream() call.

- Consider early end as an error

After the fix, even on 64K page sized aarch64, above reflink now
works as expected:

  # xfs_io -f -c "reflink $mnt/source_inlined 0 60k 4k" $mnt/dest
  linked 4096/4096 bytes at offset 61440

And results the correct file layout:

	item 9 key (258 INODE_ITEM 0) itemoff 15542 itemsize 160
		generation 10 transid 10 size 65536 nbytes 4096
		block group 0 mode 100600 links 1 uid 0 gid 0 rdev 0
		sequence 1 flags 0x0(none)
	item 10 key (258 INODE_REF 256) itemoff 15528 itemsize 14
		index 3 namelen 4 name: dest
	item 11 key (258 XATTR_ITEM 3817753667) itemoff 15445 itemsize 83
		location key (0 UNKNOWN.0 0) type XATTR
		transid 10 data_len 37 name_len 16
		name: security.selinux
		data unconfined_u:object_r:unlabeled_t:s0
	item 12 key (258 EXTENT_DATA 61440) itemoff 15392 itemsize 53
		generation 10 type 1 (regular)
		extent data disk byte 13631488 nr 4096
		extent data offset 0 nr 4096 ram 4096
		extent compression 0 (none)

The block size stored in the super block is used by subsystems outside

use our sectorsize, with the exception of mount where we first need to
use fixed values (4K) until we read the super block and can set the
sectorsize.

Replace all uses, in most cases it's fewer pointer indirections.

After the conversion to folio interfaces (but without the patch to
enable larger folio allocation), there is an LTP report about observable
performance drop on metadata heavy operations.

https://lore.kernel.org/linux-btrfs/202312221750.571925bd-oliver.sang@intel.com/

This drop is caused by the extra code of calculating the
folio_size()/folio_shift(), instead of the old hard coded
PAGE_SIZE/PAGE_SHIFT.

To slightly reduce the overhead, just cache both folio_size and
folio_shift in extent_buffer.

The two new members (u32 folio_size and u8 folio_shift) are stored
inside the holes of extent_buffer. folio_size is shared with len, which
is reduced to u32. The size of eb does not change.

The variable @bio_offset was introduced in commit 7ffd27e3 ("btrfs:

the same endio function for both data and metadata.

Later we had several changes to data and metadata endio functions:

- Data verification is handled by btrfs bio layer

- Split data and metadata endio paths

Now for data path we no longer do any verification in
end_bbio_data_read(), as the verification is handled by btrfs bio layer
already.

Thus there is no need for such bio_offset variable.

The parameter @pg_offset of btrfs_get_extent() is only utilized for
inlined extent, and we already have an ASSERT() and tree-checker, to
make sure we can only get inline extent at file offset 0.

Any invalid inline extent with non-zero file offset would be rejected by
tree-checker in the first place.

Thus the @pg_offset parameter is not really necessary, just remove it.

 "A workaround to suppress the continuous bus resets in the case that
  older devices are connected to the modern 1394 OHCI hardware and
  devices

  In IEEE 1394 Amendment (IEEE 1394a-2000), the short bus reset is added
  to resolve the shortcomings of the long bus reset in IEEE 1394-1995.
  However, it is well-known that the solution is not necessarily
  effective in the mixing environment that both IEEE 1394-1995 PHY and
  IEEE 1394a-2000 (or later) PHY exist, as described in section 8.4.6.2
  of IEEE 1394a-2000.

  The current implementation of firewire stack schedules the short bus
  reset when attempting to resolve the mismatch of gap count in the
  certain generation of bus topology. It can cause the continuous bus
  reset in the issued environment.

  The workaround simply uses the long bus reset instead of the short bus
  reset. It is desirable to detect whether the issued environment or
  not. However, the way to access PHY registers from remote note is
  firstly defined in IEEE 1394a-2000, thus it is not available in the
  case"

It is enough to define it as '__packed __aligned(4)', as '__packed'
alone means byte aligned, and can cause compiler to generate horrible
code on architectures that don't support unaligned access in case that
bvec_iter is embedded in other structures.

Pull drm fixes from Dave Airlie:
 "Bunch of fixes, xe, amdgpu, nouveau and tegra all have a few. Then
  drm/bridge including some drivers/soc fallout fixes. The biggest thing
  in here is a new unit test for some buddy allocator fixes, otherwise a
  misc fbcon, ttm unit test and one msm revert.

   - two allocation fixes + unit test

  fbcon:
   - font restore syzkaller fix

  ttm:
   - kunit test fix

  bridge:
   - fix aux-hpd leaks
   - fix aux-hpd registration
   - fix use after free in soc/qcom
   - fix boot on soc/qcom

  xe:
   - A couple of tracepoint updates from Priyanka and Lucas
   - Make sure BINDs are completed before accepting UNBINDs on LR vms
   - Don't arbitrarily restrict max number of batched binds
   - Add uapi for dumpable bos (agreed on IRC)
   - Remove unused uapi flags and a leftover comment
   - A couple of fixes related to the execlist backend

  msm:
   - DP: Revert a change which was causing a HDP regression

  amdgpu:
   - Fix potential buffer overflow
   - Fix power min cap
   - Suspend/resume fix
   - SI PM fix
   - eDP fix

  nouveau:
   - fix a misreported VRAM sizing
   - fix a regression in suspend/resume due to freeing

  tegra:
   - host1x reset fix
   - only remove existing driver if display is possible"

Pull fprobe fix from Masami Hiramatsu:

 - allocate entry_data_size buffer for each rethook instance.

   This fixes a buffer overrun bug (which leads a kernel crash)
   when fprobe user uses its entry_data in the entry_handler.
