Subject of the patch: iommu/arm-smmu: Error out only if not enough context interrupts Commit ID: 42b88ec6530fd76f1ae06de7f09830bcbca5bbd6 Why: ARM SMMU does not initialize for Broadcom Stingray SoC if bootloader reserves few contexts. Kernel should not error out if there are enough context interrupts. What kernel versions: 4.14.y and 4.18.y (applies cleanly). Before patching: Kernel does not boot using eMMC on Broadcom Stingray SoC with latest bootloader emitting this error "arm-smmu 64000000.mmu: found only 64 context interrupt(s) but 63 required" After patching: Kernel cleanly boots on the SoC. Thanks, JB
