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.

Now applied thanks.
