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
