Metrics have a field where the groups they belong to are listed like
the following from
tools/perf/pmu-events/arch/x86/skylakex/skx-metrics.json:
"MetricGroup": "PGO;TmaL1;TopdownL1;tma_L1_group",
"MetricName": "tma_frontend_bound",
The metric groups are shown in 'perf list' like the following where
TopdownL1 is a metric group:
TopdownL1:
tma_backend_bound
[This category represents fraction of slots where no uops are being
delivered due to a lack of required resources for accepting new uops
in the Backend]
tma_bad_speculation
[This category represents fraction of slots wasted due to incorrect
speculations]
tma_frontend_bound
[This category represents fraction of slots where the processor's
Frontend undersupplies its Backend]
tma_retiring
[This category represents fraction of slots utilized by useful work
i.e. issued uops that eventually get retired]
This patch adds support for a new json file in each model directory
called metricgroups.json that comprises a dictionary containing
entries that map from a metric group to a description:
{
...
"TopdownL1": "Metrics for top-down breakdown at level 1",
...
}
perf list is then updated to support this changing the above output
to:
TopdownL1: [Metrics for top-down breakdown at level 1]
Committer notes:

Introduce a helper to return the SoC SMEM ID, which is used to identify the
exact SoC model as there may be differences in the same SoC family.
Currently, cpufreq-nvmem does this completely in the driver and there has
been more interest expresed for other drivers to use this information so
lets expose a common helper to prevent redoing it in individual drivers
since this field is present on every SMEM table version.

Commit ebeb20a9cd ("soc: qcom: mdt_loader: Always invoke PAS
mem_setup") dropped the relocate check and made pas_mem_setup run
unconditionally. The code was later moved with commit f4e526ff7e
("soc: qcom: mdt_loader: Extract PAS operations") to
qcom_mdt_pas_init() effectively losing track of what was actually
done.
The assumption that PAS mem_setup can be done anytime was effectively
wrong, with no good reason and this caused regression on some SoC
that use remoteproc to bringup ath11k. One example is IPQ8074 SoC that
effectively broke resulting in remoteproc silently die and ath11k not
working.
On this SoC FW relocate is not enabled and PAS mem_setup was correctly
skipped in previous kernel version resulting in correct bringup and
function of remoteproc and ath11k.
To fix the regression, reintroduce the relocate check in
qcom_mdt_pas_init() and correctly skip PAS mem_setup where relocate is
not enabled.

the rest all all for the the NXP i.MX platforms: SoC specific bugfixes
for the iMX8 clocks and its USB-3.0 gadget device, as well as board
specific fixes for regulators and the phy on some of the i.MX boards.
The microchip risc-v and arm32 maintainers now also add a shared

The remaining fixes are all for firmware drivers, addressing mistakes in
the optee, scmi and ff-a firmware driver implementation, mostly in the
error handling code, incorrect use of the alloc_workqueue() interface in
SCMI, and compatibility with corner cases of the firmware implementation.

cc1: all warnings being treated as errors
We can check if i overflows to solve the problem. However, this doesn't make
much sense, since i == 1 and num_pages == 1 doesn't execute the body of the loop.
In addition, i < num_pages can also ensure that buf->pages[i] will not cross
the boundary. Unfortunately, this doesn't help with the problem observed here:
gcc still complains.
To fix this add a compile-time condition for the extent buffer page
array size limit, which would eventually lead to eliminating the whole
for loop.

When I implemented the storage layer bio splitting, I was under the
assumption that we'll never split metadata bios. But Qu reminded me that
this can actually happen with very old file systems with unaligned
metadata chunks and RAID0.
I still haven't seen such a case in practice, but we better handled this
case, especially as it is fairly easily to do not calling the ->end_іo
method directly in btrfs_end_io_work, and using the proper
btrfs_orig_bbio_end_io helper instead.
In addition to the old file system with unaligned metadata chunks case
documented in the commit log, the combination of the new scrub code
with Johannes pending raid-stripe-tree also triggers this case. We
spent some time debugging it and found that this patch solves
the problem.

Syzkaller got a lot of crashes like:
KASAN: use-after-free Write in *_timers*
All of these crashes point to the same memory area:
The buggy address belongs to the object at ffff88801f870000
which belongs to the cache kmalloc-8k of size 8192
The buggy address is located 5320 bytes inside of
8192-byte region [ffff88801f870000, ffff88801f872000)
This area belongs to :
batadv_priv->batadv_priv_dat->delayed_work->timer_list
The reason for these issues is the lack of synchronization. Delayed
work (batadv_dat_purge) schedules new timer/work while the device
is being deleted. As the result new timer/delayed work is set after
cancel_delayed_work_sync() was called. So after the device is freed
the timer list contains pointer to already freed memory.

thermal: intel: int340x: Add new line for UUID display
While struct_size() is normally used in situations where the structure
type already has a pointer instance, there are places where no variable
is available. In the past, this has been worked around by using a typed
NULL first argument, but this is a bit ugly. Add a helper to do this,
and replace the handful of instances of the code pattern with it.
Instances were found with this Coccinelle script:
