git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull interrupt subsystem updates from Thomas Gleixner: - Consolidate the machine_kexec_mask_interrupts() by providing a generic implementation and replacing the copy & pasta orgy in the relevant architectures. - Prevent unconditional operations on interrupt chips during kexec shutdown, which can trigger warnings in certain cases when the underlying interrupt has been shut down before. - Make the enforcement of interrupt handling in interrupt context unconditionally available, so that it actually works for non x86 related interrupt chips. The earlier enablement for ARM GIC chips set the required chip flag, but did not notice that the check was hidden behind a config switch which is not selected by ARM[64]. - Decrapify the handling of deferred interrupt affinity setting. Some interrupt chips require that affinity changes are made from the context of handling an interrupt to avoid certain race conditions. For x86 this was the default, but with interrupt remapping this requirement was lifted and a flag was introduced which tells the core code that affinity changes can be done in any context. Unrestricted affinity changes are the default for the majority of interrupt chips. RISCV has the requirement to add the deferred mode to one of it's interrupt controllers, but with the original implementation this would require to add the any context flag to all other RISC-V interrupt chips. That's backwards, so reverse the logic and require that chips, which need the deferred mode have to be marked accordingly. That avoids chasing the 'sane' chips and marking them. - Add multi-node support to the Loongarch AVEC interrupt controller driver. - The usual tiny cleanups, fixes and improvements all over the place. * tag 'irq-core-2025-01-21' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: genirq/generic_chip: Export irq_gc_mask_disable_and_ack_set() genirq/timings: Add kernel-doc for a function parameter genirq: Remove IRQ_MOVE_PCNTXT and related code x86/apic: Convert to IRQCHIP_MOVE_DEFERRED genirq: Provide IRQCHIP_MOVE_DEFERRED hexagon: Remove GENERIC_PENDING_IRQ leftover ARC: Remove GENERIC_PENDING_IRQ genirq: Remove handle_enforce_irqctx() wrapper genirq: Make handle_enforce_irqctx() unconditionally available irqchip/loongarch-avec: Add multi-nodes topology support irqchip/ts4800: Replace seq_printf() by seq_puts() irqchip/ti-sci-inta : Add module build support irqchip/ti-sci-intr: Add module build support irqchip/irq-brcmstb-l2: Replace brcmstb_l2_mask_and_ack() by generic function irqchip: keystone: Use syscon_regmap_lookup_by_phandle_args genirq/kexec: Prevent redundant IRQ masking by checking state before shutdown kexec: Consolidate machine_kexec_mask_interrupts() implementation genirq: Reuse irq_thread_fn() for forced thread case genirq: Move irq_thread_fn() further up in the code

2025-01-12arm: pxa: convert timeouts to use secs_to_jiffies()Easwar Hariharan
Commit b35108a51cf7 ("jiffies: Define secs_to_jiffies()") introduced secs_to_jiffies(). As the value here is a multiple of 1000, use secs_to_jiffies() instead of msecs_to_jiffies to avoid the multiplication. This is converted using scripts/coccinelle/misc/secs_to_jiffies.cocci with the following Coccinelle rules: @@ constant C; @@ - msecs_to_jiffies(C * 1000) + secs_to_jiffies(C) @@ constant C; @@ - msecs_to_jiffies(C * MSEC_PER_SEC) + secs_to_jiffies(C) Link: https://lkml.kernel.org/r/20241210-converge-secs-to-jiffies-v3-3-ddfefd7e9f2a@linux.microsoft.com Signed-off-by: Easwar Hariharan <eahariha@linux.microsoft.com> Cc: Alexander Gordeev <agordeev@linux.ibm.com> Cc: Andrew Lunn <andrew+netdev@lunn.ch> Cc: Anna-Maria Behnsen <anna-maria@linutronix.de> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Christian Borntraeger <borntraeger@linux.ibm.com> Cc: Christophe Leroy <christophe.leroy@csgroup.eu> Cc: Daniel Mack <daniel@zonque.org> Cc: David Airlie <airlied@gmail.com> Cc: David S.

2025-01-07ARM: dts: ti/omap: gta04: fix pm issues caused by spi moduleAndreas Kemnade
Despite CM_IDLEST1_CORE and CM_FCLKEN1_CORE behaving normal, disabling SPI leads to messages like when suspending: Powerdomain (core_pwrdm) didn't enter target state 0 and according to /sys/kernel/debug/pm_debug/count off state is not entered. That was not connected to SPI during the discussion of disabling SPI. See: https://lore.kernel.org/linux-omap/20230122100852.32ae082c@aktux/ The reason is that SPI is per default in slave mode. Linux driver will turn it to master per default. It slave mode, the powerdomain seems to be kept active if active chip select input is sensed. Fix that by explicitly disabling the SPI3 pins which used to be muxed by the bootloader since they are available on an optionally fitted header which would require dtb overlays anyways.

2025-01-06ARM: dts: qcom: sdx55: Disable USB U1/U2 entryPrashanth K
Disable U1 and U2 power-saving states to improve stability of USB. These low-power link states, designed to reduce power consumption during idle periods, can cause issues in latency-sensitive or high throughput use cases. Over the years, some of the issues seen are as follows: 1. In device mode of operation, when UVC is active, enabling U1/U2 is sometimes causing packets drops due to delay in entry/exit of intermittent these low power states. These packet drops are often reflected as missed isochronous transfers, as the controller wasn't able to send packet in that microframe interval and hence glitches are seen on the final transmitted video output. 2. On older targets like SM8150/SM8250/SM8350, there have been throughput issues seen during tethering use cases. 3. On targets like SDX75, intermittent disconnects were observed with certain cables due to impedence variations. Disabling these intermittent power states enhances device stability without affecting power usage.

2025-01-04crypto: vmac - remove unused VMAC algorithmEric Biggers
Remove the vmac64 template, as it has no known users. It also continues to have longstanding bugs such as alignment violations (see https://lore.kernel.org/r/20241226134847.6690-1-evepolonium@gmail.com/). This code was added in 2009 by commit f1939f7c5645 ("crypto: vmac - New hash algorithm for intel_txt support"). Based on the mention of intel_txt support in the commit title, it seems it was added as a prerequisite for the contemporaneous patch "intel_txt: add s3 userspace memory integrity verification" (https://lore.kernel.org/r/4ABF2B50.6070106@intel.com/). In the design proposed by that patch, when an Intel Trusted Execution Technology (TXT) enabled system resumed from suspend, the "tboot" trusted executable launched the Linux kernel without verifying userspace memory, and then the Linux kernel used VMAC to verify userspace memory. However, that patch was never merged, as reviewers had objected to the design. It was later reworked into commit 4bd96a7a8185 ("x86, tboot: Add support for S3 memory integrity protection") which made tboot verify the memory instead. Thus the VMAC support in Linux was never used. No in-tree user has appeared since then, other than potentially the usual components that allow specifying arbitrary hash algorithms by name, namely AF_ALG and dm-integrity. However there are no indications that VMAC is being used with these components. Debian Code Search and web searches for "vmac64" (the actual algorithm name) do not return any results other than the kernel itself, suggesting that it does not appear in any other code or documentation. Explicitly grepping the source code of the usual suspects (libell, iwd, cryptsetup) finds no matches either. Before 2018, the vmac code was also completely broken due to using a hardcoded nonce and the wrong endianness for the MAC. It was then fixed by commit ed331adab35b ("crypto: vmac - add nonced version with big endian digest") and commit 0917b873127c ("crypto: vmac - remove insecure version with hardcoded nonce"). These were intentionally breaking changes that changed all the computed MAC values as well as the algorithm name ("vmac" to "vmac64"). No complaints were ever received about these breaking changes, strongly suggesting the absence of users. The reason I had put some effort into fixing this code in 2018 is because it was used by an out-of-tree driver. But if it is still needed in that particular out-of-tree driver, the code can be carried in that driver instead. There is no need to carry it upstream.
