xfs_attr_sf_findname has the simple job of finding a xfs_attr_sf_entry in
the attr fork, but the convoluted calling convention obfuscates that.
Return the found entry as the return value instead of an pointer
argument, as the -ENOATTR/-EEXIST can be trivally derived from that, and
remove the basep argument, as it is equivalent of the offset of sfe in
the data for if an sfe was found, or an offset of totsize if not was
found. To simplify the totsize computation add a xfs_attr_sf_endptr
helper that returns the imaginative xfs_attr_sf_entry at the end of
the current attrs.

trace_xfs_attr_sf_lookup is currently only called by
xfs_attr_shortform_lookup, which despit it's name is a simple helper for
xfs_attr_shortform_addname, which has it's own tracing. Move the
callsite to xfs_attr_shortform_getvalue, which is the closest thing to
a high level lookup we have for the Linux xattr API.

Many of the xfs_idata_realloc callers need to set a local pointer to the

The xfs_ifork structure currently has a union of the if_root void pointer
and the if_data char pointer. In either case it is an opaque pointer
that depends on the fork format. Replace the union with a single if_data
void pointer as that is what almost all callers want. Only the symlink
NULL termination code in xfs_init_local_fork actually needs a new local
variable now.

====================
netfilter pull request 23-12-20
The following patchset contains Netfilter fixes for net:
1) Skip set commit for deleted/destroyed sets, this might trigger
double deactivation of expired elements.
2) Fix packet mangling from egress, set transport offset from
mac header for netdev/egress.
Both fixes address bugs already present in several releases.

Commit 8c5fa3b5c4df ("powerpc/64: Make ELFv2 the default for big-endian
builds"), merged in Linux-6.5-rc1 changes the calling ABI in a way
that is incompatible with the current code for the PS3's LV1 hypervisor
calls.
This change just adds the line '# CONFIG_PPC64_BIG_ENDIAN_ELF_ABI_V2 is not set'
to the ps3_defconfig file so that the PPC64_ELF_ABI_V1 is used.
Fixes run time errors like these:

In some configurations e.g. systems with CXL, a numa node can have 0
cpus and cpumask_nth() will return a cpu value that doesn't exist,
which will result in an attempt to add an entry to the wq table at a
bad index.
To fix this, when iterating the cpus for a node, skip any node that
doesn't have cpus.
Also, as a precaution, add a warning and bail if cpumask_nth() returns
a nonexistent cpu.

When testing sahara sha256 speed performance with tcrypt (mode=404) on
imx53-qsrb board, multiple "Invalid numbers of src SG." errors are
reported. This was traced to sahara_walk_and_recalc() resizing req->src
and causing the subsequent dma_map_sg() call to fail.
Now that the previous commit fixed sahara_sha_hw_links_create() to take
into account the actual request size, rather than relying on sg->length
values, the resize operation is no longer necessary.
Therefore, remove sahara_walk_and_recalc() and simplify associated logic.

Expose through debugfs device telemetry data for QAT GEN4 devices.
This allows to gather metrics about the performance and the utilization
of a device. In particular, statistics on (1) the utilization of the
PCIe channel, (2) address translation, when SVA is enabled and (3) the
internal engines for crypto and data compression.
If telemetry is supported by the firmware, the driver allocates a DMA
region and a circular buffer. When telemetry is enabled, through the
`control` attribute in debugfs, the driver sends to the firmware, via
the admin interface, the `TL_START` command. This triggers the device to
periodically gather telemetry data from hardware registers and write it
into the DMA memory region. The device writes into the shared region
every second.
The driver, every 500ms, snapshots the DMA shared region into the
circular buffer. This is then used to compute basic metric
(min/max/average) on each counter, every time the `device_data` attribute
is queried.
Telemetry counters are exposed through debugfs in the folder
/sys/kernel/debug/qat_<device>_<BDF>/telemetry.
For details, refer to debugfs-driver-qat_telemetry in Documentation/ABI.

Extend the admin interface with two new public APIs to enable
and disable the telemetry feature: adf_send_admin_tl_start() and
adf_send_admin_tl_stop().
The first, sends to the firmware, through the ICP_QAT_FW_TL_START
message, the IO address where the firmware will write telemetry
metrics and a list of ring pairs (maximum 4) to be monitored.
It returns the number of accelerators of each type supported by
this hardware. After this message is sent, the firmware starts
periodically reporting telemetry data using by writing into the
dma buffer specified as input.
The second, sends the admin message ICP_QAT_FW_TL_STOP
which stops the reporting of telemetry data.
This patch is based on earlier work done by Wojciech Ziemba.

Adds code to not execute CPT errata "when CPT_AF_DIAG[FLT_DIS] = 0 and a
CPT engine access to LLC/DRAM encounters a fault/poison, a rare case
may result in unpredictable data being delivered to a CPT engine"
workaround on CN10KA B0/CN10KB HW as it is fixed on these chips.

On CN10KA B0/CN10KB, CPT scatter gather format has modified
to support multi-seg in inline IPsec. Due to this CPT requires
new firmware and doesn't work with CN10KA0/A1 firmware. To make
HW works in backward compatibility mode or works with CN10KA0/A1
firmware, a bit(T106_MODE) is introduced in HW CSR.
This patch adds devlink parameter for configuring T106_MODE.
This patch also documents the devlink parameter under
Documentation/crypto/device_drivers.
