  Quite a lot of nilfs2 work this time around.

  Notable patch series in this pull request are:

   - "mul_u64_u64_div_u64: new implementation" by Nicolas Pitre, with
     assistance from Uwe Kleine-König. Reimplement mul_u64_u64_div_u64()
     to provide (much) more accurate results. The current implementation
     was causing Uwe some issues in the PWM drivers.

     Lasse Collin. Miscellaneous maintenance and kinor feature work to
     the xz decompressor.

     Kuan-Ying Lee. Fixes and enhancements to the gdb scripts.

   - "treewide: add missing MODULE_DESCRIPTION() macros" from Jeff
     Johnson. Adds lots of MODULE_DESCRIPTIONs, thus fixing lots of
     warnings about this.

   - "nilfs2: add support for some common ioctls" from Ryusuke Konishi.
     Adds various commonly-available ioctls to nilfs2.

   - "This series fixes a number of formatting issues in kernel doc
     comments" from Ryusuke Konishi does that.

   - "nilfs2: prevent unexpected ENOENT propagation" from Ryusuke
     Konishi. Fix issues where -ENOENT was being unintentionally and
     inappropriately returned to userspace.

   - "nilfs2: assorted cleanups" from Huang Xiaojia.

   - "nilfs2: fix potential issues with empty b-tree nodes" from Ryusuke
     Konishi fixes some issues which can occur on corrupted nilfs2
     filesystems.

   - "scripts/decode_stacktrace.sh: improve error reporting and
     usability" from Luca Ceresoli does those things"

The fault-inject.h users across the kernel need to add a lot of #ifdef
CONFIG_FAULT_INJECTION to cater for shortcomings in the header.  Make
fault-inject.h self-contained for CONFIG_FAULT_INJECTION=n, and add stubs
for DECLARE_FAULT_ATTR(), setup_fault_attr(), should_fail_ex(), and
should_fail() to allow removal of conditional compilation.

'Legacy Queue & Single Doorbell Support (LSDBS)' field in the controller
capabilities register is supposed to report whether the legacy single
doorbell mode is supported in the controller or not. But some controllers
report '1' in this field which corresponds to 'LSDB not supported', but
they indeed support LSDB. So let's add a quirk to handle those controllers.

If the quirk is enabled by the controller driver, then LSDBS register field
will be ignored and legacy single doorbell mode is assumed to be enabled
always.

Prepare so we'll be able to read various other HCI registers.  While at it,
fix the HCPID & HCMID register names to stand for what they really are.
Also replace the pm_runtime_{get/put}_sync() calls in auto_hibern8_show to
ufshcd_rpm_{get/put}_sync() as any host controller register reads should.

If the user sets use_mcq_mode to 0, the host will try to activate the LSDB
mode unconditionally even when the LSDBS of device HCI cap is 1. This makes
commands time out and causes device probing to fail.

To prevent that problem, check the LSDBS cap when MCQ is not supported.

Eric Biggers <ebiggers@kernel.org> says:

Add support for Flash Memory Protector (FMP), which is the inline
encryption hardware on Exynos and Exynos-based SoCs.

Specifically, add support for the "traditional FMP mode" that works on
many Exynos-based SoCs including gs101.  This is the mode that uses
"software keys" and is compatible with the upstream kernel's existing
inline encryption framework in the block and filesystem layers.  I
plan to add support for the wrapped key support on gs101 at a later
time.

Tested on gs101 (specifically Pixel 6) by running the 'encrypt' group
of xfstests on a filesystem mounted with the 'inlinecrypt' mount
option.

This patchset applies to v6.10-rc6, and it has no prerequisites that
aren't already upstream.

Since the nonstandard inline encryption support on Exynos SoCs requires
that raw cryptographic keys be copied into the PRDT, it is desirable to
zeroize those keys after each request to keep them from being left in
memory.  Therefore, add a quirk bit that enables the zeroization.

We could instead do the zeroization unconditionally.  However, using a
quirk bit avoids adding the zeroization overhead to standard devices.

Add a variant op to allow host drivers to initialize nonstandard
crypto-related fields in the PRDT.  This is needed to support inline
encryption on the "Exynos" UFS controller.

Note that this will be used together with the support for overriding the
PRDT entry size that was already added by commit ada1e653a5ea ("scsi: ufs:
core: Allow UFS host drivers to override the sg entry size").
