[PATCH v3 0/6] hw/arm/smmuv3: Correct stream ID and event address handling

[Simon Veith]

While working on the Linux SMMUv3 driver, I noticed a few cases where the QEMU
SMMUv3 behavior relating to stream tables was inconsistent with our hardware.

Also, when debugging those differences, I found that the errors reported through
the QEMU SMMUv3 event queue contained the address fields in an incorrect
position.

These patches correct the QEMU SMMUv3 behavior to match the specification (and
the behavior that I observed in our hardware). Linux guests normally will not
notice these issues, but other SMMUv3 driver implementations might.

Changes in v2:

* New patch "hw/arm/smmuv3: Correct SMMU_BASE_ADDR_MASK value" added
* Updated patch "hw/arm/smmuv3: Check stream IDs against actual table LOG2SIZE"
* Updated patch "hw/arm/smmuv3: Align stream table base address to table size"

Changes in v3:

* No changes, but sending again to correct a patch submission mishap that
  confused Patchew
