2025-05-19KVM: arm64: vgic-its: Add debugfs interface to expose ITS tablesJing Zhang
This commit introduces a debugfs interface to display the contents of the VGIC Interrupt Translation Service (ITS) tables. The ITS tables map Device/Event IDs to Interrupt IDs and target processors. Exposing this information through debugfs allows for easier inspection and debugging of the interrupt routing configuration. The debugfs interface presents the ITS table data in a tabular format: Device ID: 0x0, Event ID Range: [0 - 31] EVENT_ID INTID HWINTID TARGET COL_ID HW ----------------------------------------------- 0 8192 0 0 0 0 1 8193 0 0 0 0 2 8194 0 2 2 0 Device ID: 0x18, Event ID Range: [0 - 3] EVENT_ID INTID HWINTID TARGET COL_ID HW ----------------------------------------------- 0 8225 0 0 0 0 1 8226 0 1 1 0 2 8227 0 3 3 0 Device ID: 0x10, Event ID Range: [0 - 7] EVENT_ID INTID HWINTID TARGET COL_ID HW ----------------------------------------------- 0 8229 0 3 3 1 1 8230 0 0 0 1 2 8231 0 1 1 1 3 8232 0 2 2 1 4 8233 0 3 3 1 The output is generated using the seq_file interface, allowing for efficient handling of potentially large ITS tables. This interface is read-only and does not allow modification of the ITS tables. It is intended for debugging and informational purposes only.

2025-05-19docs: align with scripts/syscall.tbl migrationJesung Yang
Update the documentation to reflect the migration of the following architectures to the centralized syscall table format: arc, arm64, csky, hexagon, loongarch, nios2, openrisc, riscv As of commit 3db80c999debbad ("riscv: convert to generic syscall table"), these architectures no longer rely on include/uapi/asm-generic/unistd.h. Instead, syscall table headers (syscall_table_{32,64}.h) are generated by scripts/syscalltbl.sh based on entries in scripts/syscall.tbl, with ABIs specified in arch/*/kernel/Makefile.syscalls. For the convenience of developers working with older kernel versions, the original documentation is fully retained, with new sections added to cover the scripts/syscall.tbl approach. Verified with `make htmldocs`.

2025-05-19can: bcm: add missing rcu read protection for procfs contentOliver Hartkopp
When the procfs content is generated for a bcm_op which is in the process to be removed the procfs output might show unreliable data (UAF). As the removal of bcm_op's is already implemented with rcu handling this patch adds the missing rcu_read_lock() and makes sure the list entries are properly removed under rcu protection.

2025-05-19can: bcm: add locking for bcm_op runtime updatesOliver Hartkopp
The CAN broadcast manager (CAN BCM) can send a sequence of CAN frames via hrtimer. The content and also the length of the sequence can be changed resp reduced at runtime where the 'currframe' counter is then set to zero. Although this appeared to be a safe operation the updates of 'currframe' can be triggered from user space and hrtimer context in bcm_can_tx(). Anderson Nascimento created a proof of concept that triggered a KASAN slab-out-of-bounds read access which can be prevented with a spin_lock_bh. At the rework of bcm_can_tx() the 'count' variable has been moved into the protected section as this variable can be modified from both contexts too.

2025-05-19spi: spi_amd: Add HIDDMA basic write supportRaju Rangoju
SPI index mode has hardware limitation of transferring only 64 bytes per transaction due to fixed number of FIFO registers. This constraint leads to performance issues when reading/writing data to/from NAND/NOR flash devices, as the controller must issue multiple requests to read/write 64-byte chunks, even if the slave can transfer up to 2 or 4 KB in a single transaction. The AMD HID2 SPI controller supports DMA mode, allowing for reading/writing up to 4 KB of data in a single transaction. The existing spi_amd driver already supports HID2 DMA read operations. This patch introduces changes to implement HID2 DMA single mode basic write support for the HID2 SPI controller.

Current suspend/resume logic has one issue. In suspend, will config register when call sdhci_suspend_host(), but at this time, can't guarantee host in runtime resume state. If not, the per clock is gate off, access register will hang. In sdhci_esdhc_suspend/sdhci_esdhc_resume, remove sdhci_suspend_host() and sdhci_resume_host(), all are handled in runtime PM callbacks except the wakeup irq setting. For wakeup irq setting, use pm_runtime_get_sync() in sdhci_esdhc_suspend() to make sure clock gate on. Remove pinctrl_pm_select_default_state() in sdhci_esdhc_resume, because pm_runtime_force_resume() already config the pinctrl state according to ios timing, and here config the default pinctrl state again is wrong for SDIO3.0 device if it keep power in suspend.

We don't (and can't) configure the hardware correctly if the number of channels exceeds the weight of the TDM mask. Report that constraint in startup of FE.

Move the MSIOF register and register bit definitions from the MSIOF SPI driver to the existing header file <linux/spi/sh_msiof.h>, so they can be shared with the MSIOF I2S driver.

2025-05-19spi: sh-msiof: Double maximum DMA transfer size using two groupsGeert Uytterhoeven
The maximum DMA transfer size is limited by the maximum values that can be written to the word count fields (WDLENx) in the Transmit and Control Data Registers (SITDR2/SIRDR2). As all MSIOF variants support transferring data of multiple (two or four) groups, the maximum size can be doubled by using two groups instead of one, thus reducing setup overhead for very large SPI transfers.

2025-05-19spi: sh-msiof: Increase TX FIFO size for R-Car V4H/V4MGeert Uytterhoeven
The MSIOF transmit FIFOs on R-Car V4H and V4M have 256 stages. Add a new family-specific match entry to handle this. Add quirk match entries for older R-Car Gen4 Socs (R-Car V3U and S4-8) that have transmit FIFOs with only 64 stages, just like on R-Car Gen3. Update the (unused) definition of SIFCTR_TFUA for consistency.

2025-05-19spi: sh-msiof: Correct RX FIFO size for R-Car Gen3Geert Uytterhoeven
According to the R-Car Gen3 Hardware Manual Errata for Rev 0.55 of September 28, 2017, the MSIOF receive FIFOs on R-Car Gen3 SoCs have room for 256 words of 32 bits. Note that this change has no actual impact on the behavior of the driver, as SPI_CONTROLLER_MUST_TX is set, and transfer size is currenty limited to the minimum of the transmit and receive FIFO sizes.
