Cover letter [PATCH v2 0/3] iommu/arm=smmu: Add driver for ARM SMMUv3 devices

Hi all,

This is version two of the patches I originally posted here:

http://www.spinics.net/lists/arm-kernel/msg416881.html

Changes since version one include:

- Lazy allocation of the level-2 stream table on device-add
- Limit stream table size based on SIDSIZE (maximum 21-bit atm)
- Fixed detection of linear stream table
- Fixed typo in RECINVSID CR2 field
- Added cmdline option for changing default bypass behaviour to fault
- Check IDR0.HYP before EL2 TLBI
- Reworked stream table so that each level-2 entry resolves 256 SIDs (i.e. a PCI bus)

All feedback welcome,

Will
