The cgrp_ancestor_storage has two drawbacks:
- it's not guaranteed that the member immediately follows struct cgrp in
cgroup_root (root cgroup's ancestors[0] might thus point to a padding
and not in cgrp_ancestor_storage proper),
- this idiom raises warnings with -Wflex-array-member-not-at-end.
Instead of relying on the auxiliary member in cgroup_root, define the
0-th level ancestor inside struct cgroup (needed for static allocation
of cgrp_dfl_root), deeper cgroups would allocate flexible
_low_ancestors[]. Unionized alias through ancestors[] will
transparently join the two ranges.
The above change would still leave the flexible array at the end of
struct cgroup inside cgroup_root, so move cgrp also towards the end of
cgroup_root to resolve the -Wflex-array-member-not-at-end.

When CPU 15 is offlined, subpartitions_cpus gets cleared because no CPUs
remain available for the top_cpuset, forcing partitions to share CPUs with
the top_cpuset. In this scenario, disabling the remote partition triggers
a warning stating that effective_xcpus is not a subset of
subpartitions_cpus. Partitions should be invalidated in this case to
inform users that the partition is now invalid(cpus are shared with
top_cpuset).
To fix this issue:
1. Only emit the warning only if subpartitions_cpus is not empty and the
effective_xcpus is not a subset of subpartitions_cpus.
2. During the CPU hotplug process, invalidate partitions if
subpartitions_cpus is empty.

On x86-64, this_cpu_cmpxchg() uses CMPXCHG without LOCK prefix which
means it is only safe for the local CPU and not for multiple CPUs.
Recently the commit 36df6e3dbd7e ("cgroup: make css_rstat_updated nmi
safe") make css_rstat_updated lockless and uses lockless list to allow
reentrancy. Since css_rstat_updated can invoked from process context,
IRQ and NMI, it uses this_cpu_cmpxchg() to select the winner which will
inset the lockless lnode into the global per-cpu lockless list.
However the commit missed one case where lockless node of a cgroup can
be accessed and modified by another CPU doing the flushing. Basically
llist_del_first_init() in css_process_update_tree().
On a cursory look, it can be questioned how css_process_update_tree()
can see a lockless node in global lockless list where the updater is at
this_cpu_cmpxchg() and before llist_add() call in css_rstat_updated().
This can indeed happen in the presence of IRQs/NMI.
Consider this scenario: Updater for cgroup stat C on CPU A in process
context is after llist_on_list() check and before this_cpu_cmpxchg() in
css_rstat_updated() where it get interrupted by IRQ/NMI. In the IRQ/NMI
context, a new updater calls css_rstat_updated() for same cgroup C and
successfully inserts rstatc_pcpu->lnode.
Now concurrently CPU B is running the flusher and it calls
llist_del_first_init() for CPU A and got rstatc_pcpu->lnode of cgroup C
which was added by the IRQ/NMI updater.
Now imagine CPU B calling init_llist_node() on cgroup C's
rstatc_pcpu->lnode of CPU A and on CPU A, the process context updater
calling this_cpu_cmpxchg(rstatc_pcpu->lnode) concurrently.
The CMPXCNG without LOCK on CPU A is not safe and thus we need LOCK
prefix.
In Meta's fleet running the kernel with the commit 36df6e3dbd7e, we are
observing on some machines the memcg stats are getting skewed by more
than the actual memory on the system. On close inspection, we noticed
that lockless node for a workload for specific CPU was in the bad state
and thus all the updates on that CPU for that cgroup was being lost.
To confirm if this skew was indeed due to this CMPXCHG without LOCK in
css_rstat_updated(), we created a repro (using AI) at [1] which shows
that CMPXCHG without LOCK creates almost the same lnode corruption as
seem in Meta's fleet and with LOCK CMPXCHG the issue does not
reproduces.

"This is entirely SoC clk drivers.
The majority diff wise is for the new Rockchip and Qualcomm clk
drivers which is mostly lines and lines of data structures to describe
the clk hardware in these SoCs. Beyond those two, Renesas continues to
incrementally add clks to their SoC drivers, causing them to show up
higher in the diffstat this time because they added quite a few clks
all over the place.
Overall it is a semi-quiet release that has some new clk drivers and
the usual fixes for clock data that was wrong or missing and
non-critical cleanups that plug error paths or fix typos.
New Drivers:
- Qualcomm IPQ5424 Network Subsystem Clock Controller
- Qualcomm SM8750 Video Clock Controller
- Rockchip RV1126B and RK3506 clock drivers
- i.MX8ULP SIM LPAV clock driver

Use-after-free and double-free bugs can be very difficult to track down.
The kernel is good at tracking these and preventing bad pages from being
used/created through simple checks gated behind "check_pages_enabled".
Currently, the only ways to enable this flag is by building with
CONFIG_DEBUG_VM, or as a side effect of other checks such as
init_on_{alloc, free}, page_poisoning, or debug_pagealloc among others.
These solutions are powerful, but may often be too coarse in balancing
the performance vs. safety that a user may want, particularly in
latency-sensitive production environments.
Introduce a new boot parameter "check_pages", which enables page checking
with no other side effects. It takes kstrbool-able inputs as an argument
(i.e. 0/1, true/false, on/off, ...). This patch is backwards-compatible;
setting CONFIG_DEBUG_VM still enables page checking.

* tag 'clk-imx-6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/abelvesa/linux:
clk: imx: add driver for imx8ulp's sim lpav
dt-bindings: clock: document 8ULP's SIM LPAV
clk: imx: imx8mp-audiomix: use devm_auxiliary_device_create() to simple code
clk: imx: Add some delay before deassert the reset
Pull Microchip clk driver updates from Claudiu Beznea:
- PolarFire SoC clock driver updates to use regmaps instead of iomem
addresses; with it, the reset control driver support for non-auxiliary
bus probing was included as it now depends on the regmap registered
by the clock controller driver
- A cleanup patch for the LAN966X clk driver
* tag 'clk-microchip-6.19' of https://git.kernel.org/pub/scm/linux/kernel/git/at91/linux:
reset: mpfs: add non-auxiliary bus probing
clk: lan966x: remove unused dt-bindings include
clk: microchip: mpfs: use regmap for clocks
dt-bindings: clk: microchip: mpfs: remove first reg region
