Patch series in this pull request:
- The 3 patch series "ida: Remove the ida_simple_xxx() API" from Christophe Jaillet completes the removal of this legacy IDR API. - The 9 patch series "panic: introduce panic status function family" from Jinchao Wang provides a number of cleanups to the panic code and its various helpers, which were rather ad-hoc and scattered all over the place. - The 5 patch series "tools/delaytop: implement real-time keyboard interaction support" from Fan Yu adds a few nice user-facing usability changes to the delaytop monitoring tool. - The 3 patch series "efi: Fix EFI boot with kexec handover (KHO)" from Evangelos Petrongonas fixes a panic which was happening with the combination of EFI and KHO. - The 2 patch series "Squashfs: performance improvement and a sanity check" from Phillip Lougher teaches squashfs's lseek() about SEEK_DATA/SEEK_HOLE. A mere 150x speedup was measured for a well-chosen microbenchmark. - Plus another 50-odd singleton patches all over the place. -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQTTMBEPP41GrTpTJgfdBJ7gKXxAjgUCaN78zwAKCRDdBJ7gKXxA jhLeAQCddTv0XtSUTrvBvmrJVUBrQQeJc+LtNopMIjfAF/WAWAEAogSVKxg+HHEB GaVixx4zDriNzEqrqiCx9rm4l+YooQA= =XRe0 -----END PGP SIGNATURE----- Merge tag 'mm-nonmm-stable-2025-10-02-15-29' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull non-MM updates from Andrew Morton: - "ida: Remove the ida_simple_xxx() API" from Christophe Jaillet completes the removal of this legacy IDR API - "panic: introduce panic status function family" from Jinchao Wang provides a number of cleanups to the panic code and its various helpers, which were rather ad-hoc and scattered all over the place - "tools/delaytop: implement real-time keyboard interaction support" from Fan Yu adds a few nice user-facing usability changes to the delaytop monitoring tool - "efi: Fix EFI boot with kexec handover (KHO)" from Evangelos Petrongonas fixes a panic which was happening with the combination of EFI and KHO - "Squashfs: performance improvement and a sanity check" from Phillip Lougher teaches squashfs's lseek() about SEEK_DATA/SEEK_HOLE.

soc: driver updates for 6.18
Lots of platform specific updates for Qualcomm SoCs, including a new TEE subsystem driver for the Qualcomm QTEE firmware interface. Added support for the Apple A11 SoC in drivers that are shared with the M1/M2 series, among more updates for those. Smaller platform specific driver updates for Renesas, ASpeed, Broadcom, Nvidia, Mediatek, Amlogic, TI, Allwinner, and Freescale SoCs. Driver updates in the cache controller, memory controller and reset controller subsystems. SCMI firmware updates to add more features and improve robustness. This includes support for having multiple SCMI providers in a single system. TEE subsystem support for protected DMA-bufs, allowing hardware to access memory areas that managed by the kernel but remain inaccessible from the CPU in EL1/EL0. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmjdpaoACgkQmmx57+YA GNnBXA//QgmFXYGG7QfB825mt0orKZxpfpLcwvqO7hkWgbXtl7Gokw2lGYN6bwLu zvY4MQ/bVoZ8R5uTVmuaSHBRsttSen8mBf+V0vzsBM/DRRVxvIN/7TESrY3J7Dtx J5syHKIBiUtdkDebWWC6jIElczIBItsd03Ln4Xjjt8Vas5YOO4n44zFrPo+FwlN/ I6D2K86AiNZTtUCDMtB6VfJ6YtjYBWcWnJm7FXw/vE8FAXdZUnNWnZ8hbdQ5GaME JZGepUhONaOMUoGNZNaDGw511RdPhYzPjj9rCsIx2qdsRO9/4tJ8ccpW2aUMYh8c nA6w8Hj8jCwco6aYYrDUDV9uRtURDrmyJgTJBNLU05e/L+MuJ3IZNlzHFWlsxIAE vhyTdmg/P04ClQyixCl67IH/66F/0smX9C+1761LrD7GTdfR92KPl5W6q+DPBg/x yf+s2p3+f7ItV5XobKOrbf3w0xazeDb5o/EK8BufMx9vSe9bpzJ0gOf0CmNXEpyZ owAhbh6wXX1YwPcyA9LHv6gthyJwc/3fLu49ggMZP2rU01ccKOYn9H0cr7C8NVmy wEpJR0lp5aSw2oRkPkxB6sFmUohcpr8/OXGGJuvCXkYsUY1BEup4lewvbIWK4WoE c84kbbaHsjgFhe3IRlQw3G4KLYQT3jRtF7fH+gPx556BcI6K+lg= =mcZR -----END PGP SIGNATURE----- Merge tag 'soc-drivers-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull SoC driver updates from Arnd Bergmann: "Lots of platform specific updates for Qualcomm SoCs, including a new TEE subsystem driver for the Qualcomm QTEE firmware interface.

- Add functionality to provide runtime firmware updates for the non-x86 parts
of an AMD platform like the security processor (ASP) firmware, modules etc, for example. The intent being that these updates are interim, live fixups before a proper BIOS update can be attempted - Add guest support for AMD's Secure AVIC feature which gives encrypted guests the needed protection against a malicious hypervisor generating unexpected interrupts and injecting them into such guest, thus interfering with its operation in an unexpected and negative manner. The advantage of this scheme is that the guest determines which interrupts and when to accept them vs leaving that to the benevolence (or not) of the hypervisor - Strictly separate the startup code from the rest of the kernel where former is executed from the initial 1:1 mapping of memory. The problem was that the toolchain-generated version of the code was being executed from a different mapping of memory than what was "assumed" during code generation, needing an ever-growing pile of fixups for absolute memory references which are invalid in the early, 1:1 memory mapping during boot. The major advantage of this is that there's no need to check the 1:1 mapping portion of the code for absolute relocations anymore and get rid of the RIP_REL_REF() macro sprinkling all over the place.

efi/x86: Memory protection on EfiGcdMemoryTypeMoreReliable
Check for needed memory protection changes on EFI DXE GCD memory space descriptors with type EfiGcdMemoryTypeMoreReliable in addition to EfiGcdMemoryTypeSystemMemory. This fixes a fault on entry into the decompressed kernel from the EFI stub that occurs when the memory allocated for the decompressed kernel is more reliable memory, has NX/XP set, and the kernel needs to use the EFI DXE protocol to adjust memory protections. The memory descriptors returned by the DXE protocol GetMemorySpaceDescriptor() service use a different GCD memory type to distinguish more reliable memory ranges from their conventional counterparts. This is in contrast to the EFI memory descriptors returned by the EFI GetMemoryMap() service which use the EFI_MEMORY_MORE_RELIABLE memory attributes flag to identify EFI_CONVENTIONAL_MEMORY type regions that have this additional property.

soc: fixes for 6.17, part 3
There are a few minor code fixes for tegra firmware, i.MX firmware and the
eyeq reset controller, and a MAINTAINERS update as Alyssa Rosenzweig moves
on to non-kernel projects. The other changes are all for devicetree files:
- Multiple Marvell Armada SoCs need changes to fix PCIe, audio and SATA
- A socfpga board fails to probe the ethernet phy
- The two temperature sensors on i.MX8MP are swapped
- Allwinner devicetree files cause build-time warnings
- Two Rockchip based boards need corrections for headphone detection
and SPI flash

More Qualcomm device driver updates for v6.18
Introduce support for loading firmware into the QUP serial engines from Linux, which allows deferring selection of which protocol (uart, i2c, spi, etc) a given SE should have until the OS loads. Also introduce the "object invoke" interface in the SCM driver, to provide interface to the Qualcomm TEE driver. -----BEGIN PGP SIGNATURE----- iQJJBAABCgAzFiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAmjPXH0VHGFuZGVyc3Nv bkBrZXJuZWwub3JnAAoJEAsfOT8Nma3Fn/8P/2cgGz6MOdQJA45IEk7Staab/XA4 5l4p8gde3vro9JR/mB+zC/wg5ULg1fhmQwBAFNUfvuyCChyPVoIgtaHXh2z5yvrt nKwjmeetw4OHw53edBApll8r5ahu4dtJyiK3WcMhFV6hHle4lIaBjYBLLQ3ZRNpd 1OY/AO5yYxStzQvYaEBVRbDMZF+i1mIzbeIjVPwe8gy1MaGreGzpXCvmf6eVbgMt SVN8bhTXsmg2zEh9Fi8mzDKgkhT9jK7HrE4n0/Hum8jER6o+ClgPW2OjpVJHIVPO TTeKy3Qd0EDFnI8Sbn+BcxRmWlKAXXmhosQxEnP+2/okpegPGJEfyQufpKOoyUcz qshJUX8/BP8M72Pm8LBnbWq0bqFQSW60b5HNC67Ih0edfIgpqB+xpgMTtgR8WwHZ KVsoGiE+yWfR+qPk+lBtZD0zWqKYT/qj5575YGxNvlWc//Itcy+NIg6Y2wkEvX8O BZI28+RZFoeBSKa3FqyBLHozul+WcZB3mK5SUiZFLWQlJb5mrgfE0yVyvVw/UgN3 jhJ8QQCI9x/Enm7OhXkWsZik93YwdFl0P4CRALGVr4wqnD3n0IjkmeXoq6r4265B LuoI5P41wWRR3x7Qam0neOk930pgZ95punGM4/geWW0nMGbIXCNoU7yJ64czS9Xo hbYXWu9OXys+nCF8 =TulG -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmjTCYQACgkQmmx57+YA GNlD5RAAsWpUIaZsu3S1aBl/B2qHJJAIuDsluJ4kvCSlVT+51ctRqyTd/7vxup7Q zBUojCCAmdLnAkym5H1y9qx3Jen1dC7BE9tYAbAjFi0NQYKdMaueik2EVffdQjoJ 69BBpmGU/moABY/+bU2OH7xfECq2ZCim0pPmQ2jMEekpGRfVV4glzjzKItyIFBsj 2C/sIccnr9jlyrtMkrh/ACitnyIvLstZpR70SXY8Y1yNdkYyNn7DTj+H7bWhLaZG 35VmqIWcxmXUBckxBagQr8lgAFsOGAYF7psJnVZRR9r/ivlA1V92giE92wLh5mO9 NBCz8f2zhz1IhHfywUBU2f6zHb4xI3UATyHxeFZ7XUHBw/FIMI/x+JyZgrkxIszZ mFs2Q/T9SxHmwIL5qfxQvQ6zHOE/My4oTQrchP5d2fQcQ2j00xVpB29K9QZVbwpR gmEhdFOBmnaZRPVrD6kQRaQdqaEbgOxxJOWLfTe1ezuS7x716CUcp/AoSZYzEqTh dEr8c+rXr4bg+okk6y6zl9gn4qBWOYmzs1H+2r1Duh5tVms7LkmESlY0/ciEGaX7 /fvaVS4LeSXMcUckJ6guGdhXNAKQD7l4ZCz7xmnyPgu8urf9pukUZ81ajZiXAC0d bTStK3btx9AEvFK2b/MzEoN3Tcz9f+eGCHJbjI8cjQpmNnqYDgk= =JuVO -----END PGP SIGNATURE----- Merge tag 'qcom-drivers-for-6.18-2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers More Qualcomm device driver updates for v6.18 Introduce support for loading firmware into the QUP serial engines from Linux, which allows deferring selection of which protocol (uart, i2c, spi, etc) a given SE should have until the OS loads.

The IPC shared memory can reside in system memory or SRAM. In the latter
case the memory-region property is expected not to be present, so do not
warn about it.

Arm SCMI updates/fixes for v6.18
These SCMI changes bring a mix of improvements, fixes, and cleanups:
1. Device Tree bindings - allow multiple SCMI instances by suffixing
node names (Nikunj Kela).
2. Code hardening - constify both scmi_{transport,voltage_proto}_ops
so they reside in read-only memory (Christophe JAILLET).
3. VirtIO transport initialization - set DRIVER_OK before SCMI probing
to prevent potential stalls; while recent rework removes the practical
risk, this ensures correctness (Junnan Wu).
4. Quirk handling - fix a critical bug by preventing writes to string
constants, avoiding faults in read-only memory (Johan Hovold).
5. i.MX SCMI MISC protocol - extend support to discover board info,
retrieve configuration and build data, and document the new
MISC_BOARD_INFO command; all handled gracefully if unsupported (Peng Fan).
6. Logging cleanup - simplify device tree node name logging by using
the %pOF format to print full paths (Krzysztof Kozlowski).

firmware: qcom: scm: add support for object invocation
Qualcomm TEE (QTEE) hosts Trusted Applications (TAs) and services in the secure world, accessed via objects. A QTEE client can invoke these objects to request services. Similarly, QTEE can request services from the nonsecure world using objects exported to the secure world. Add low-level primitives to facilitate the invocation of objects hosted in QTEE, as well as those hosted in the nonsecure world. If support for object invocation is available, the qcom_scm allocates a dedicated child platform device. The driver for this device communicates with QTEE using low-level primitives.

efi: support booting with kexec handover (KHO)
When KHO (Kexec HandOver) is enabled, it sets up scratch memory regions early during device tree scanning. After kexec, the new kernel exclusively uses this region for memory allocations during boot up to the initialization of the page allocator However, when booting with EFI, EFI's reserve_regions() uses memblock_remove(0, PHYS_ADDR_MAX) to clear all memory regions before rebuilding them from EFI data. This destroys KHO scratch regions and their flags, thus causing a kernel panic, as there are no scratch memory regions. Instead of wholesale removal, iterate through memory regions and only remove non-KHO ones. This preserves KHO scratch regions, which are good known memory, while still allowing EFI to rebuild its memory map.

Now that the boot code is being cleaned up and refactored, most of it is being moved into .init.text [where it arguably belongs] but that implies that when booting on such strict EFI firmware, we need to take care to map .init.text (and the .altinstr_aux section that follows it) read-execute as well.

firmware: ti_sci: Enable abort handling of entry to LPM
The PM co-processor (device manager or DM) adds the ability to abort entry to a low power mode by clearing the mode selection in the latest version of its firmware (11.01.09) [1]. Enable the ti_sci driver to support the LPM abort call which clears the low power mode selection of the DM. This fixes an issue where failed system suspend attempts would cause subsequent suspends to fail. After system suspend completes, regardless of if system suspend succeeds or fails, the ->complete() hook in TI SCI will be called. In the ->complete() hook, a message will be sent to the DM to clear the current low power mode selection. Clearing the low power mode selection unconditionally will not cause any error in the DM.

firmware: arm_scmi: Mark VirtIO ready before registering scmi_virtio_driver
After commit 20bda12a0ea0 (“firmware: arm_scmi: Make VirtIO transport a
standalone driver”), the VirtIO transport probes independently. During
scmi_virtio_probe, scmi_probe() is called, which intune invokes
scmi_protocol_acquire() that sends a message over the virtqueue and
waits for a reply.
Previously, DRIVER_OK was only set after scmi_vio_probe, in the core
virtio via virtio_dev_probe(). According to the Virtio spec (3.1 Device
Initialization):
| The driver MUST NOT send any buffer available notifications to the
| device before setting DRIVER_OK.
Some type-1 hypervisors block available-buffer notifications until the
driver is marked OK. In such cases, scmi_vio_probe stalls in
scmi_wait_for_reply(), and the probe never completes.
Resolve this by setting DRIVER_OK immediately after the device-specific
setup, so scmi_probe() can safely send notifications.
Note after splitting the transports into modules, the probe sequence
changed a bit. We can no longer rely on virtio_device_ready() being
called by the core in virtio_dev_probe(), because scmi_vio_probe()
doesn’t complete until the core SCMI stack runs scmi_probe(), which
immediately issues the initial BASE protocol exchanges.

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. 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.
