irqchip/gic-v3: Add Altera SoCFPGA Agilex5 GIC600 DMA32 erratum workaround

2026-09-07T19:53:05+00:00

Agilex5 integrates GIC600 with an ACE-lite interface limited to a 32-bit address bus, so the ITS can only access the first 4 GB of physical address space. Register intel,socfpga-agilex5 on the existing dma_32bit_impaired_platforms list so ITS allocations use GFP_DMA32. The workaround is guarded by ALTERA_ERRATUM_AGILEX5_2_1_23, which is selected by ARCH_INTEL_SOCFPGA as all Agilex5 devices are affected. This limitation is documented as Agilex 5 ES Device Errata 2.1.23 (825514).

irqchip/gic-v3-its: Don't WARN on LPI free allocation failure

2026-09-07T19:53:05+00:00

free_lpi_range() cannot give LPIs back to the allocator without allocating a struct lpi_range to describe the freed range, so it returns -ENOMEM (its only failure mode) when that allocation fails, and its_lpi_free() turns this into a WARN_ON(). syzbot triggers the WARN_ON() by injecting a slab allocation failure on device teardown, which with panic_on_warn becomes a panic: WARNING: drivers/irqchip/irq-gic-v3-its.c:2251 at its_msi_teardown+0x3a4/0x424 its_msi_teardown+0x3a4/0x424 msi_remove_device_irq_domain+0x16c/0x27c msi_device_data_release+0x38/0x9c The failure is transient and the consequence benign: the freed range is simply never returned to the allocator. This does not warrant a WARN_ON() backtrace, so log a rate-limited error instead.

Now that __irq_domain_instantiate() automatically sets IRQ_DOMAIN_FLAG_DESTROY_GC when dgc_info is provided, the explicit flag in the irq_domain_info is redundant. Remove it.

irqchip/pruss-intc: Use scoped lock guard and devm_mutex_init

2026-09-07T19:47:51+00:00

Scoped locking simplifies the return path in a spot, and removes a couple lines in another couple spots. The devm mutex init will call mutex_destroy() for us on remove, which only really matters when CONFIG_DEBUG_MUTEXES is set, but it is nice to do anyway.

irqchip/gic-v5: Preserve ICC_CR0_EL1 state

2026-09-07T19:44:17+00:00

In addition to EN, ICC_CR0_EL1 contains other fields, such as LINK and LINK_IDLE. The driver only needs to modify EN, and must preserve the values of all other fields when enabling or disabling the CPU interface. Define the missing LINK and LINK_IDLE fields, and use read-modify-write accesses to update EN without affecting the rest of ICC_CR0_EL1.

treewide: refresh kmalloc_obj() conversions

2026-09-05T04:37:00+00:00

This is another run of the Coccinelle script for converting kmalloc() family of allocations to kmalloc_obj() via the existing rules in scripts/coccinelle/api/kmalloc_objs.cocci This catches both the set of kmalloc() uses added since the first kmalloc_obj() conversions in v7.0 and adds a large group missed in the first pass due to Coccinelle not interacting well with the cleanup.h scoped_...() family of macros[1]. I worked around this with spatch's "--macro-file" argument to a file with all the scoped_...() macros mapped to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control flow indicator I could find. Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc, riscv, and s390 with no new warnings.
