7856a56541 Many singleton patches - please see the various changelogs for details.
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.
 
 "xz: Updates to license, filters, and compression options" from Lasse
 Collin.  Miscellaneous maintenance and kinor feature work to the xz
 decompressor.
 
 "Fix some GDB command error and add some GDB commands" from 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.

b97c0741c7 scsi: Expand all create*_workqueue() invocations
The workqueue maintainer wants to remove the create*_workqueue() macros
because these macros always set the WQ_MEM_RECLAIM flag and because these
only support literal workqueue names. Hence this patch that replaces the
create*_workqueue() invocations with the definition of this macro. The
WQ_MEM_RECLAIM flag has been retained because I think that flag is necessary
for workqueues created by storage drivers. This patch has been generated by
running spatch and git clang-format. spatch has been invoked as follows:

spatch --in-place --sp-file expand-create-workqueue.spatch $(git grep -lEw 'create_(freezable_|singlethread_|)workqueue' */scsi */ufs)

The contents of the expand-create-workqueue.spatch file is as follows:

13d0cecb46 scsi: bfa: Ensure the copied buf is NUL terminated
Currently, we allocate a nbytes-sized kernel buffer and copy nbytes from
userspace to that buffer. Later, we use sscanf on this buffer but we don't
ensure that the string is terminated inside the buffer, this can lead to
OOB read when using sscanf. Fix this issue by using memdup_user_nul instead
of memdup_user.

37126399da scsi: bfa: Fix function pointer type mismatch for state machines
The bfa driver is full of state machines and a generic abstraction layer
for them. This relies on casting function pointers, but that is no longer
allowed when CONFIG_CFI_CLANG is enabled and causes a huge number of
warnings like:

drivers/scsi/bfa/bfad.c:169:3: error: cast from 'void (*)(struct bfad_s *, enum bfad_sm_event)' to 'bfa_sm_t' (aka 'void (*)(void *, int)') converts to incompatible function type [-Werror,-Wcast-function-type-strict]
                bfa_sm_set_state(bfad, bfad_sm_created);
                ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Rework the mechanism to no longer require the function pointer casts, by
having separate types for each individual state machine. This in turn
requires moving the enum definitions for each state machine into the header
files in order to define the typedef.

b69600231f scsi: bfa: Fix function pointer type mismatch for hcb_qe->cbfn
Some callback functions used here take a boolean argument, others take a
status argument. This breaks KCFI type checking, so clang now warns about
the function pointer cast:

drivers/scsi/bfa/bfad_bsg.c:2138:29: error: cast from 'void (*)(void *, enum bfa_status)' to 'bfa_cb_cbfn_t' (aka 'void (*)(void *, enum bfa_boolean)') converts to incompatible function type [-Werror,-Wcast-function-type-strict]

Assuming the code is actually correct here and the callers always match the
argument types of the callee, rework this to replace the explicit cast with
a union of the two pointer types. This does not change the behavior of the
code, so if something is actually broken here, a larger rework may be
necessary.

b54e1e47b5 scsi: bfa: Drop redundant pci_enable_pcie_error_reporting()
pci_enable_pcie_error_reporting() enables the device to send ERR_*
Messages.  Since commit f26e58bf6f ("PCI/AER: Enable error reporting when
AER is native"), the PCI core does this for all devices during enumeration,
so the driver doesn't need to do it itself.

Remove the redundant pci_enable_pcie_error_reporting() call from the
driver.  Also remove the corresponding pci_disable_pcie_error_reporting()
from the driver .remove() path.

Note that this only controls ERR_* Messages from the device.  An ERR_*
Message may cause the Root Port to generate an interrupt, depending on the
AER Root Error Command register managed by the AER service driver.

012d98dae4 scsi: bfa: Remove useless DMA-32 fallback configuration
As stated in [1], dma_set_mask() with a 64-bit mask never fails if
dev->dma_mask is non-NULL. So, if it fails, the 32-bit case will also fail
for the same reason.

Simplify code and remove some dead code accordingly.
