+Subject: ACPI: processor_idle: Fix invalid comparison with insertion sort for latency
+
+From: Kuan-Wei Chiu <visitorckw@gmail.com>
+
+commit 233323f9b9f828cd7cd5145ad811c1990b692542 upstream.
+
+The acpi_cst_latency_cmp() comparison function currently used for
+sorting C-state latencies does not satisfy transitivity, causing
+incorrect sorting results.
+
+Specifically, if there are two valid acpi_processor_cx elements A and B
+and one invalid element C, it may occur that A < B, A = C, and B = C.
+Sorting algorithms assume that if A < B and A = C, then C < B, leading
+to incorrect ordering.
+
+Given the small size of the array (<=8), we replace the library sort
+function with a simple insertion sort that properly ignores invalid
+elements and sorts valid ones based on latency. This change ensures
+correct ordering of the C-state latencies.
+
+Fixes: 65ea8f2c6e23 ("ACPI: processor idle: Fix up C-state latency if not ordered")

+Subject: cpufreq: Allow drivers to advertise boost enabled
+
+From: Mario Limonciello <mario.limonciello@amd.com>
+
+commit 102fa9c4b439ca3bd93d13fb53f5b7592d96a109 upstream.
+
+The behavior introduced in commit f37a4d6b4a2c ("cpufreq: Fix per-policy
+boost behavior on SoCs using cpufreq_boost_set_sw()") sets up the boost
+policy incorrectly when boost has been enabled by the platform firmware
+initially even if a driver sets the policy up.
+
+This is because policy_has_boost_freq() assumes that there is a frequency
+table set up by the driver and that the boost frequencies are advertised
+in that table. This assumption doesn't work for acpi-cpufreq or
+amd-pstate. Only use this check to enable boost if it's not already
+enabled instead of also disabling it if alreayd enabled.

+Subject: Fix userfaultfd_api to return EINVAL as expected
+
+From: Audra Mitchell <audra@redhat.com>
+
+commit 1723f04caacb32cadc4e063725d836a0c4450694 upstream.
+
+Currently if we request a feature that is not set in the Kernel config we
+fail silently and return all the available features. However, the man
+page indicates we should return an EINVAL.
+
+We need to fix this issue since we can end up with a Kernel warning should
+a program request the feature UFFD_FEATURE_WP_UNPOPULATED on a kernel with
+the config not set with this feature.

+Subject: libceph: fix race between delayed_work() and ceph_monc_stop()
+
+From: Ilya Dryomov <idryomov@gmail.com>
+
+commit 69c7b2fe4c9cc1d3b1186d1c5606627ecf0de883 upstream.
+
+The way the delayed work is handled in ceph_monc_stop() is prone to
+races with mon_fault() and possibly also finish_hunting(). Both of
+these can requeue the delayed work which wouldn't be canceled by any of
+the following code in case that happens after cancel_delayed_work_sync()
+runs -- __close_session() doesn't mess with the delayed work in order
+to avoid interfering with the hunting interval logic. This part was
+missed in commit b5d91704f53e ("libceph: behave in mon_fault() if
+cur_mon < 0") and use-after-free can still ensue on monc and objects
+that hang off of it, with monc->auth and monc->monmap being
+particularly susceptible to quickly being reused.
+
+To fix this:
+
+- clear monc->cur_mon and monc->hunting as part of closing the session
+ in ceph_monc_stop()
+- bail from delayed_work() if monc->cur_mon is cleared, similar to how
+ it's done in mon_fault() and finish_hunting() (based on monc->hunting)
+- call cancel_delayed_work_sync() after the session is closed

+
+From: Ekansh Gupta <quic_ekangupt@quicinc.com>
+
+commit bfb6b07d2a30ffe98864d8cfc31fc00470063025 upstream.
+
+When user is requesting for DSP capability, the process pd type is
+getting updated to USER_PD which is incorrect as DSP will assume the
+process which is making the request is a user PD and this will never
+get updated back to the original value. The actual PD type should not
+be updated for capability request and it should be serviced by the
+respective PD on DSP side. Don't change process's PD type for DSP
+capability request.

+
+From: Ekansh Gupta <quic_ekangupt@quicinc.com>
+
+commit 4cb7915f0a35e2fcc4be60b912c4be35cd830957 upstream.
+
+The DSP capability request call expects 2 arguments. First is the
+information about the total number of attributes to be copied from
+DSP and second is the information about the buffer where the DSP
+needs to copy the information. The current design is passing the
+information about the size to be copied from DSP which would be
+considered as a bad argument to the call by DSP causing a failure
+suggesting the same. The second argument carries the information
+about the buffer where the DSP needs to copy the capability
+information and the size to be copied. As the first entry of
+capability attribute is getting skipped, same should also be
+considered while sending the information to DSP. Add changes to
+pass proper arguments to DSP.

+From: Ekansh Gupta <quic_ekangupt@quicinc.com>
+
+commit ad0bd973a033003ca578c42a760d1dc77aeea15e upstream.
+
+Audio PD daemon send the name as part of the init IOCTL call. This
+name needs to be copied to kernel for which memory is allocated.
+This memory is never freed which might result in memory leak. Free
+the memory when it is not needed.

+Subject: misc: fastrpc: Fix ownership reassignment of remote heap
+
+From: Ekansh Gupta <quic_ekangupt@quicinc.com>
+
+commit a6f2f158f1ac4893a4967993105712bf3dad32d9 upstream.
+
+Audio PD daemon will allocate memory for audio PD dynamic loading
+usage when it is attaching for the first time to audio PD. As
+part of this, the memory ownership is moved to the VM where
+audio PD can use it. In case daemon process is killed without any
+impact to DSP audio PD, the daemon process will retry to attach to
+audio PD and in this case memory won't be reallocated. If the invoke
+fails due to any reason, as part of err_invoke, the memory ownership
+is getting reassigned to HLOS even when the memory was not allocated.
+At this time the audio PD might still be using the memory and an
+attemp of ownership reassignment would result in memory issue.

+From: Ekansh Gupta <quic_ekangupt@quicinc.com>
+
+commit bab2f5e8fd5d2f759db26b78d9db57412888f187 upstream.
+
+Untrusted application with access to only non-secure fastrpc device
+node can attach to root_pd or static PDs if it can make the respective
+init request. This can cause problems as the untrusted application
+can send bad requests to root_pd or static PDs. Add changes to reject
+attach to privileged PDs if the request is being made using non-secure
+fastrpc device node.

+Subject: mm/damon/core: merge regions aggressively when max_nr_regions is unmet
+
+From: SeongJae Park <sj@kernel.org>
+
+commit 310d6c15e9104c99d5d9d0ff8e5383a79da7d5e6 upstream.
+
+DAMON keeps the number of regions under max_nr_regions by skipping regions
+split operations when doing so can make the number higher than the limit.
+It works well for preventing violation of the limit. But, if somehow the
+violation happens, it cannot recovery well depending on the situation. In
+detail, if the real number of regions having different access pattern is
+higher than the limit, the mechanism cannot reduce the number below the
+limit. In such a case, the system could suffer from high monitoring
+overhead of DAMON.
+
+The violation can actually happen. For an example, the user could reduce
+max_nr_regions while DAMON is running, to be lower than the current number
+of regions. Fix the problem by repeating the merge operations with
+increasing aggressiveness in kdamond_merge_regions() for the case, until
+the limit is met.

+
+From: Gavin Shan <gshan@redhat.com>
+
+commit 9fd154ba926b34c833b7bfc4c14ee2e931b3d743 upstream.
+
+For shmem files, it's possible that PMD-sized page cache can't be
+supported by xarray. For example, 512MB page cache on ARM64 when the base
+page size is 64KB can't be supported by xarray. It leads to errors as the
+following messages indicate when this sort of xarray entry is split.

+
+Fix it by disabling PMD-sized page cache when HPAGE_PMD_ORDER is larger
+than MAX_PAGECACHE_ORDER. As Matthew Wilcox pointed, the page cache in a
+shmem file isn't represented by a multi-index entry and doesn't have this
+limitation when the xarry entry is split until commit 6b24ca4a1a8d ("mm:
+Use multi-index entries in the page cache").

+Subject: pmdomain: qcom: rpmhpd: Skip retention level for Power Domains
+
+From: Taniya Das <quic_tdas@quicinc.com>
+
+commit ddab91f4b2de5c5b46e312a90107d9353087d8ea upstream.
+
+In the cases where the power domain connected to logics is allowed to
+transition from a level(L)-->power collapse(0)-->retention(1) or
+vice versa retention(1)-->power collapse(0)-->level(L) will cause the
+logic to lose the configurations. The ARC does not support retention
+to collapse transition on MxC rails.
+
+The targets from SM8450 onwards the PLL logics of clock controllers are
+connected to MxC rails and the recommended configurations are carried
+out during the clock controller probes. The MxC transition as mentioned
+above should be skipped to ensure the PLL settings are intact across
+clock controller power on & off.
+
+On older targets that do not split MX into MxA and MxC does not collapse
+the logic and it is parked always at RETENTION, thus this issue is never
+observed on those targets.

+Subject: wireguard: allowedips: avoid unaligned 64-bit memory accesses
+
+From: Helge Deller <deller@kernel.org>
+
+commit 948f991c62a4018fb81d85804eeab3029c6209f8 upstream.
+
+On the parisc platform, the kernel issues kernel warnings because
+swap_endian() tries to load a 128-bit IPv6 address from an unaligned
+memory location:
+
+ Kernel: unaligned access to 0x55f4688c in wg_allowedips_insert_v6+0x2c/0x80 [wireguard] (iir 0xf3010df)
+ Kernel: unaligned access to 0x55f46884 in wg_allowedips_insert_v6+0x38/0x80 [wireguard] (iir 0xf2010dc)
+
+Avoid such unaligned memory accesses by instead using the
+get_unaligned_be64() helper macro.

+Subject: wireguard: selftests: use acpi=off instead of -no-acpi for recent QEMU

+
+commit 2cb489eb8dfc291060516df313ff31f4f9f3d794 upstream.
+
+QEMU 9.0 removed -no-acpi, in favor of machine properties, so update the
+Makefile to use the correct QEMU invocation.
