Updates for the interrupt core subsystem:
- Prevent a interrupt migration related live lock in handle_edge_irq()
If the interrupt affinity is moved to a new target CPU and the
interrupt is currently handled on the previous target CPU for edge type
interrupts the handler might get stuck on the previous target for a
long time, which causes both involved CPUs to waste cycles and
eventually run into a soft-lockup situation.
Solve this by checking whether the interrupt is redirected to a new
target CPU and if the interrupt is handled on that new target CPU, busy
wait for completion instead of masking it and sending the pending but
which would cause the old CPU to re-run the handler and in the worst
case repeating this excercise for a long time.
This only works on architectures which use single CPU interrupt
targets, but that's so far the only ones where this behaviour has been
observed.
- Add a kunit test for interrupt disable depth counts
The nested interrupt disable depth has been an issue in the past
especially vs. free_irq(), interrupt shutdown and CPU hotplug and their
interactions. The test exercises the combinations of these scenarios
and checks for correctness.

unwind_user/deferred: Add unwind_user_faultable()
Add a new API to retrieve a user space callstack called unwind_user_faultable(). The difference between this user space stack tracer from the current user space stack tracer is that this must be called from faultable context as it may use routines to access user space data that needs to be faulted in. It can be safely called from entering or exiting a system call as the code can still be faulted in there. This code is based on work by Josh Poimboeuf's deferred unwinding code: Link: https://lore.kernel.org/all/6052e8487746603bdb29b65f4033e739092d9925.1737511963.git.jpoimboe@kernel.org/ Cc: Masami Hiramatsu <mhiramat@kernel.org> Cc: Mathieu Desnoyers <mathieu.desnoyers@efficios.com> Cc: Josh Poimboeuf <jpoimboe@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Ingo Molnar <mingo@kernel.org> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Arnaldo Carvalho de Melo <acme@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Andrii Nakryiko <andrii@kernel.org> Cc: Indu Bhagat <indu.bhagat@oracle.com> Cc: "Jose E.

unwind_user: Add user space unwinding API with frame pointer support
Introduce a generic API for unwinding user stacks. In order to expand user space unwinding to be able to handle more complex scenarios, such as deferred unwinding and reading user space information, create a generic interface that all architectures can use that support the various unwinding methods. This is an alternative method for handling user space stack traces from the simple stack_trace_save_user() API. This does not replace that interface, but this interface will be used to expand the functionality of user space stack walking. None of the structures introduced will be exposed to user space tooling. Support for frame pointer unwinding is added. For an architecture to support frame pointer unwinding it needs to enable CONFIG_HAVE_UNWIND_USER_FP and define ARCH_INIT_USER_FP_FRAME. By encoding the frame offsets in struct unwind_user_frame, much of this code can also be reused for future unwinder implementations like sframe.

soc: new SoC support for 6.17
These five newly supported chips come with both devicetree descriptions
and the changes to wire them up to the build system for easier bisection.
The chips in question are:
- Marvell PXA1908 was the first 64-bit mobile phone chip from Marvell
in the product line that started with the Digital StrongARM SA1100
based PDAs and continued with the Intel PXA2xx that dominated early
smartphones. This one only made it only into a few products before the
entire product line was cut in 2015.
- The QiLai SoC is made by RISC-V core designer Andes Technologies
and is in the 'Voyager' reference board in MicroATX form factor.
It uses four in-order AX45MP cores, which is the midrange product
from Andes.
- CIX P1 is one of the few Arm chips designed for small workstations,
and this one uses 12 Cortex-A720/A520 cores, making it also one
of the only ARMv9.2 machines that one can but at the moment.
- Axiado AX3000 is an embedded chip with relative small Cortex-A53
CPU cores described as a "Trusted Control/Compute Unit" that can
be used as a BMC in servers. In addition to the usual I/O, this one
comes with 10GBit ethernet and and a 4TOPS NPU.
- Sophgo SG2000 is an embedded chip that comes with both RISC-V
and Arm cores that can run Linux. This was already supported for
RISC-V but now it also works on Arm
One more chip, the Black Sesame C1200 did not make it in tirm for the
merge window.

soc: driver updates for 6.17
Changes are all over the place, but very little sticks out as noteworthy. There is a new misc driver for the Raspberry Pi 5's RP1 multifunction I/O chip, along with hooking it up to the pinctrl and clk frameworks. The reset controller and memory subsystems have mainly small updates, but there are two new reset drivers for the K230 and VC1800B SoCs, and new memory driver support for Tegra264. The ARM SMCCC and SCMI firmware drivers gain a few more features that should help them be supported across more environments. Similarly, the SoC specific firmware on Tegra and Qualcomm get minor enhancements and chip support. In the drivers/soc/ directory, the ASPEED LPC snoop driver gets an overhaul for code robustness, the Tegra and Qualcomm and NXP drivers grow to support more chips, while the Hisilicon, Mediatek and Renesas drivers see mostly janitorial fixes. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmiEmIcACgkQmmx57+YA GNkE4g/6A2OKti+qtIsLt10zS7paGP38ftu9ad27WC54AOGgVk4ZXt8mVGRmqOf+ BICIM+wc4gehdvRJTRnq3gZg3e1puuYdcMuBOh4qsghRMjdYUKfNairtn/iX7d+f e5auzz5/gV7MWNM7jiQNydCqZSeV6u2/cqD5iRCrRgaB5FOG4yY1BkAsah1UzZjk MycudqjkK4IX5zp5oqXB/PoesULAbB2unjvfw194LATYSqmcRLQRWFdv4aM0R6ba TDP5x0d95nhMTNWif3495zc2WxdSYzbD4lNv44RPpKDywqBj+qFBI/EpMFkxQ5Hy cqv60Dm+/tx+DBO/Ma0zJzsV4ChRIEBNkTUh36OxmYxq70x1T4FEynZ6IT8a8dXD ltjHwOcTHp1M0OpNj+PIFBD+ohWFWKOo+T9GRtTInLjUGBlJA6LK9i4Lb0DaIyRt DmmvbZCwh0PI/nZiyQzw7rsXWwqDcqeF8FScw+9ooBk7Z7Jr1gMc52ya0qrRWQ8w Tr3D+lNE0aDfErnx4RrNsjD8lpX4nOfRFvuWSTlWqkBjGhoDP/tnNi2RCWmbXo2Z PDDWLnECo6o1aIxYO/tHjbFKVJB38p4e/LLP89htu8dFxSZKnVzxosnOvEVWS8+Y a0oZb9j1tAOYHmMWDm+zaQ7BlK9CMURNTdUcnqNqIvZpHnHz9M8= =7T40 -----END PGP SIGNATURE----- Merge tag 'soc-drivers-6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull SoC driver updates from Arnd Bergmann: "Changes are all over the place, but very little sticks out as noteworthy.

soc: dt changes for 6.17
There are a few new variants of existing chips:
- mt6572 is an older mobile phone chip from mediatek that was
extremely popular a decade ago but never got upstreamed until now.
- exynos2200 is a recent high-end mobile phone chip used in a
few Samsung phones like the Galaxy S22
- Renesas R-Car V4M-7 (R8A779H2) is an updated version of R-Car V4M
(R8A779H0) and used in automotive applications
- Tegra264 is a new chip from NVIDIA, but support is fairly minimal
for now, and not much information is public about it.
There are five more chips in a separate branch, as those are new
chip families that I merged along with the necessary infrastructure.
New board support is not that exciting, with a total of 33 newly
added machines here:
- Evaluation platforms for the chips above, plus TI am62d2 and
Sophgo sg2042.
- Six 32-bit industrial boards based on stm32, imx6 and am33 chips,
plus eight 64-bit rockchips rk33xx/rk35xx, am62d2, t527, imx8 and
imx95.
- Two newly added ASPEED BMC based motherboards, and one that got
removed
- Phones and Tablets based on 32-bit mt6572, tegra30 and 64-bit
msm8976 SoCs
- Three Laptops based on Mediatek mt8186 and Qualcomm Snapdragon X1
- A set-top box based on Amlogic meson-gxm.
Updates for existing machines are spread over all the above families.
One notable change here is support for the RP1 I/O chip used in
Raspberry Pi 5.

Staging changes for 6.17-rc1
Here is the "big" set of staging driver changes for 6.17-rc1. That's in
quotes as it really isn't all that big of a set of changes this
development cycle at all.
Major things that stand out are:
- gpib cleanups and tweaks with the majority of the big issues now
taken care of. Odds are it will move out of staging/ in the next
merge window if all goes well.
- more constant cleanups and layer removals from the rtl8723bs driver.
It's amazing how many layers deep they really are, all cleanups here
are great to see
- axis-fifo sysfs api removed and debugfs api added. The sysfs api
didn't work at all so obviously no one was using it. Add the same
information into debugfs as that's the proper place for it, and make
it actually work.
- Remaining changes is lots of small checkpatch cleanups, most of
which seem to have come from a Debconf session where people were
encouraged to submit their first kernel patch, a nice thing to see
happen again.
All of these have been in linux-next with no reported issues.

PCI: Move is_pciehp check out of pciehp_is_native()
pci_bridge_d3_possible() seeks to forbid runtime power management on: * Non Hot-Plug Capable PCIe ports which are nevertheless ACPI slots (recognizable as: bridge->is_hotplug_bridge && !bridge->is_pciehp) * Hot-Plug Capable PCIe ports for which platform firmware has not granted PCIe Native Hot-Plug control to the operating system (recognizable as: bridge->is_pciehp && !pciehp_is_native(bridge)) Somewhat confusingly, the check for is_hotplug_bridge is in pci_bridge_d3_possible(), whereas the one for is_pciehp is in pciehp_is_native(). For clarity, check is_pciehp directly in pci_bridge_d3_possible() (and in the other caller of pciehp_is_native(), hotplug_is_native()). Rephrase the code comment preceding these checks to no longer mention "System Management Mode", which is an x86 term inappropriate in generic PCI code. Likewise no longer mention "Thunderbolt on non-Macs", because there is nothing Thunderbolt-specific about these checks. It used to be the case that non-Macs relied on the platform for Thunderbolt tunnel management and hotplug, but they've since moved to OS-native tunnel management (as Macs always have), hence the code comment is no longer accurate. There is a subsequent check for is_hotplug_bridge further down in pci_bridge_d3_possible(). Change the check to is_pciehp because any ports matching "bridge->is_hotplug_bridge && !bridge->is_pciehp" are already filtered out at the top of the function. Do the same for another check in acpi_pci_bridge_d3(), which is called from pci_bridge_d3_possible() via platform_pci_bridge_d3(). No functional change intended.

PCI: pciehp: Use is_pciehp instead of is_hotplug_bridge
The PCIe hotplug driver calculates the depth of a nested hotplug port by looking at the is_hotplug_bridge flag. The depth is used as lockdep class to tell hotplug ports apart. The is_hotplug_bridge flag encompasses ACPI slots handled by the ACPI hotplug driver, hence the calculated depth may be too high. Avoid by checking the is_pciehp flag instead. This glitch likely has no user-visible impact: ACPI slots typically only exist at the Root Port level, not in nested hotplug hierarchies. Also, CONFIG_LOCKDEP is usually only used by developers. So this is just for the sake of correctness.

PCI/portdrv: Use is_pciehp instead of is_hotplug_bridge
The PCIe port driver erroneously creates a subdevice for hotplug on ACPI
slots which are handled by the ACPI hotplug driver.
Avoid by checking the is_pciehp flag instead of is_hotplug_bridge when
deciding whether to create a subdevice. The latter encompasses ACPI slots
whereas the former doesn't.
The superfluous subdevice has no real negative impact, it occupies memory
and interrupt resources but otherwise just sits there waiting for
interrupts from the slot that are never signaled.

PCI/ACPI: Fix runtime PM ref imbalance on Hot-Plug Capable ports
pci_bridge_d3_possible() is called from both pcie_portdrv_probe() and
pcie_portdrv_remove() to determine whether runtime power management shall
be enabled (on probe) or disabled (on remove) on a PCIe port.
The underlying assumption is that pci_bridge_d3_possible() always returns
the same value, else a runtime PM reference imbalance would occur. That
assumption is not given if the PCIe port is inaccessible on remove due to
hot-unplug: pci_bridge_d3_possible() calls pciehp_is_native(), which
accesses Config Space to determine whether the port is Hot-Plug Capable.
An inaccessible port returns "all ones", which is converted to "all
zeroes" by pcie_capability_read_dword(). Hence the port no longer seems
Hot-Plug Capable on remove even though it was on probe.
The resulting runtime PM ref imbalance causes warning messages such as:
pcieport 0000:02:04.0: Runtime PM usage count underflow!
Avoid the Config Space access (and thus the runtime PM ref imbalance) by
caching the Hot-Plug Capable bit in struct pci_dev.
The struct already contains an "is_hotplug_bridge" flag, which however is
not only set on Hot-Plug Capable PCIe ports, but also Conventional PCI
Hot-Plug bridges and ACPI slots. The flag identifies bridges which are
allocated additional MMIO and bus number resources to allow for hierarchy
expansion.
The kernel is somewhat sloppily using "is_hotplug_bridge" in a number of
places to identify Hot-Plug Capable PCIe ports, even though the flag
encompasses other devices. Subsequent commits replace these occurrences
with the new flag to clearly delineate Hot-Plug Capable PCIe ports from
other kinds of hotplug bridges.
Document the existing "is_hotplug_bridge" and the new "is_pciehp" flag
and document the (non-obvious) requirement that pci_bridge_d3_possible()
always returns the same value across the entire lifetime of a bridge,
including its hot-removal.

tracing: Remove "__attribute__()" from the type field of event format
With CONFIG_DEBUG_INFO_BTF=y and PAHOLE_HAS_BTF_TAG=y, `__user` is
converted to `__attribute__((btf_type_tag("user")))`. In this case,
some syscall events have it for __user data, like below;
/sys/kernel/tracing # cat events/syscalls/sys_enter_openat/format
name: sys_enter_openat
ID: 720
format:
field:unsigned short common_type; offset:0; size:2; signed:0;
field:unsigned char common_flags; offset:2; size:1; signed:0;
field:unsigned char common_preempt_count; offset:3; size:1; signed:0;
field:int common_pid; offset:4; size:4; signed:1;
field:int __syscall_nr; offset:8; size:4; signed:1;
field:int dfd; offset:16; size:8; signed:0;
field:const char __attribute__((btf_type_tag("user"))) * filename; offset:24; size:8; signed:0;
field:int flags; offset:32; size:8; signed:0;
field:umode_t mode; offset:40; size:8; signed:0;
Then the trace event filter fails to set the string acceptable flag
(FILTER_PTR_STRING) to the field and rejects setting string filter;
# echo 'filename.ustring ~ "*ftracetest-dir.wbx24v*"' \
>> events/syscalls/sys_enter_openat/filter
sh: write error: Invalid argument
# cat error_log
[ 723.743637] event filter parse error: error: Expecting numeric field
Command: filename.ustring ~ "*ftracetest-dir.wbx24v*"
Since this __attribute__ makes format parsing complicated and not
needed, remove the __attribute__(.*) from the type string.

KVM/arm64 changes for 6.17, round #1
- Host driver for GICv5, the next generation interrupt controller for
arm64, including support for interrupt routing, MSIs, interrupt
translation and wired interrupts.
- Use FEAT_GCIE_LEGACY on GICv5 systems to virtualize GICv3 VMs on
GICv5 hardware, leveraging the legacy VGIC interface.
- Userspace control of the 'nASSGIcap' GICv3 feature, allowing
userspace to disable support for SGIs w/o an active state on hardware
that previously advertised it unconditionally.
- Map supporting endpoints with cacheable memory attributes on systems
with FEAT_S2FWB and DIC where KVM no longer needs to perform cache
maintenance on the address range.
- Nested support for FEAT_RAS and FEAT_DoubleFault2, allowing the guest
hypervisor to inject external aborts into an L2 VM and take traps of
masked external aborts to the hypervisor.
- Convert more system register sanitization to the config-driven
implementation.
- Fixes to the visibility of EL2 registers, namely making VGICv3 system
registers accessible through the VGIC device instead of the ONE_REG
vCPU ioctls.
- Various cleanups and minor fixes.

pwm: imx-tpm: Reset counter if CMOD is 0
As per the i.MX93 TRM, section 67.3.2.1 "MOD register update", the value
of the TPM counter does NOT get updated when writing MOD.MOD unless
SC.CMOD != 0. Therefore, with the current code, assuming the following
sequence:
1) pwm_disable()
2) pwm_apply_might_sleep() /* period is changed here */
3) pwm_enable()
and assuming only one channel is active, if CNT.COUNT is higher than the
MOD.MOD value written during the pwm_apply_might_sleep() call then, when
re-enabling the PWM during pwm_enable(), the counter will end up resetting
after UINT32_MAX - CNT.COUNT + MOD.MOD cycles instead of MOD.MOD cycles as
normally expected.
Fix this problem by forcing a reset of the TPM counter before MOD.MOD is
written.

pwm: mediatek: Fix duty and period setting
The period generated by the hardware is
(PWMDWIDTH + 1) << CLKDIV) / freq
according to my tests with a signal analyser and also the documentation.
The current algorithm doesn't consider the `+ 1` part and so configures
slightly too high periods. The same issue exists for the duty cycle
setting. So subtract 1 from both the register values for period and
duty cycle. If period is 0, bail out, if duty_cycle is 0, just disable
the PWM which results in a constant low output.

regulator: core: correct convergence check in regulator_set_voltage()
The logic in regulator_set_voltage() which checks for a non-convergence
condition on a stepped regulator is flawed.
regulator_set_voltage() checks if the error in target voltage has increased
or decreased, and returns -EWOULDBLOCK if the error has not decreased
enough. The correct non-convergence condition is:
new_delta - delta > -rdev->constraints->max_uV_step
or equivalently:
delta - new_delta < rdev->constraints->max_uV_step
But the currently used condition is:
new_delta - delta > rdev->constraints->max_uV_step
Which may cause an infinite loop if the voltage error doesn't converge.
Fix this by correcting the convergence condition.

jfs: fix metapage reference count leak in dbAllocCtl
In dbAllocCtl(), read_metapage() increases the reference count of the
metapage. However, when dp->tree.budmin < 0, the function returns -EIO
without calling release_metapage() to decrease the reference count,
leading to a memory leak.
Add release_metapage(mp) before the error return to properly manage
the metapage reference count and prevent the leak.

ktest.pl: Add new PATCHCHECK_SKIP option to skip testing individual commits
When testing a series of commits that also includes changes to the Linux tools directory, it is useless to test the changes in tools as they may not affect the kernel itself. Doing tests on the kernel for changes that do not affect the kernel is a waste of time. Add a PATCHCHECK_SKIP that takes a series of shas that will be skipped while doing the individual commit tests. For example, the runtime verification may have a series of commits like: $ git log --abbrev-commit --pretty=oneline fac5493251a6~1..HEAD |

Merge tag 'kvm-x86-sev-6.17' of https://github.com/kvm-x86/linux into HEAD
KVM SEV cache maintenance changes for 6.17 - Drop a superfluous WBINVD (on all CPUs!) when destroying a VM. - Use WBNOINVD instead of WBINVD when possible, for SEV cache maintenance, e.g. to minimize collateral damage when reclaiming memory from an SEV guest. - When reclaiming memory from an SEV guest, only do cache flushes on CPUs that have ever run a vCPU for the guest, i.e. don't flush the caches for CPUs that can't possibly have cache lines with dirty, encrypted data. |

Merge tag 'kvm-x86-svm-6.17' of https://github.com/kvm-x86/linux into HEAD
KVM SVM changes for 6.17 Drop KVM's rejection of SNP's SMT and single-socket policy restrictions, and instead rely on firmware to verify that the policy can actually be supported. Don't bother checking that requested policy(s) can actually be satisfied, as an incompatible policy doesn't put the kernel at risk in any way, and providing guarantees with respect to the physical topology is outside of KVM's purview. |

Merge tag 'kvm-x86-selftests-6.17' of https://github.com/kvm-x86/linux into HEAD
KVM selftests changes for 6.17 - Fix a comment typo. - Verify KVM is loaded when getting any KVM module param so that attempting to run a selftest without kvm.ko loaded results in a SKIP message about KVM not being loaded/enabled, versus some random parameter not existing. - SKIP tests that hit EACCES when attempting to access a file, with a "Root required?" help message. In most cases, the test just needs to be run with elevated permissions. |
