Measurements for one particular UFS controller + UFS device show a 25%
higher read bandwidth if the maximum data buffer size is increased from 512
KiB to 1 MiB. Hence increase the maximum size of the data buffer associated
with a single request from SCSI_DEFAULT_MAX_SECTORS (1024) * 512 bytes =
512 KiB to 1 MiB.
Notes:
- The maximum data buffer size supported by the UFSHCI specification
is 65535 * 256 KiB or about 16 GiB.
- The maximum data buffer size for READ(10) commands is 65535 logical
blocks. To transfer more than 65535 * 4096 bytes = 255 MiB with a single
SCSI command, the READ(16) command is required. Support for READ(16) is
optional in the UFS 3.1 and UFS 4.0 standards.

Reduce the START STOP UNIT command timeout to one second since on Android
devices a kernel panic is triggered if an attempt to suspend the system
takes more than 20 seconds. One second should be enough for the START STOP
UNIT command since this command completes in less than a millisecond for
the UFS devices I have access to.

commit 93b0d91787 upstream.
mfill_atomic_install_pte() checks page->mapping to detect whether one page
is used in the page cache. However as pointed out by Matthew, the page
can logically be a tail page rather than always the head in the case of
uffd minor mode with UFFDIO_CONTINUE. It means we could wrongly install
one pte with shmem thp tail page assuming it's an anonymous page.
It's not that clear even for anonymous page, since normally anonymous
pages also have page->mapping being setup with the anon vma. It's safe
here only because the only such caller to mfill_atomic_install_pte() is
always passing in a newly allocated page (mcopy_atomic_pte()), whose
page->mapping is not yet setup. However that's not extremely obvious
either.
For either of above, use page_mapping() instead.

Fix this by changing the memory size allocated for copy_name from
UDF_NAME_LEN(254) to UDF_NAME_LEN_CS0(255), because the total length
(lfi) of subsequent memcpy can be up to 255.

commit fb1dec44c6 upstream.
[[ NOTE: this is completely untested by the author, but included solely
because, as noted in commit df57d73276 ("mmc: sdhci-pci: Fix
SDHCI_RESET_ALL for CQHCI for Intel GLK-based controllers"), "other
drivers using CQHCI might benefit from a similar change, if they
also have CQHCI reset by SDHCI_RESET_ALL." We've now seen the same
bug on at least MSM, Arasan, and Intel hardware. ]]
SDHCI_RESET_ALL resets will reset the hardware CQE state, but we aren't
tracking that properly in software. When out of sync, we may trigger
various timeouts.
It's not typical to perform resets while CQE is enabled, but this may
occur in some suspend or error recovery scenarios.
Include this fix by way of the new sdhci_and_cqhci_reset() helper.
This patch depends on (and should not compile without) the patch
entitled "mmc: cqhci: Provide helper for resetting both SDHCI and
CQHCI".

commit a8d1b1647b upstream.
When performing seeding on a zoned filesystem it is necessary to
initialize each zoned device's btrfs_zoned_device_info structure,
otherwise mounting the filesystem will cause a NULL pointer dereference.
This was uncovered by fstests' testcase btrfs/163.
