[PATCH v4 0/3] iommu/arm-smmu-v3: permit users to disable msi polling

[Barry Song]

patch 1/3 and patch 2/3 are the preparation of patch 3/3 which permits users
to disable MSI-based polling by cmd line.

-v4:
  with respect to Robin's comments
  * cleanup the code of the existing module parameter disable_bypass
  * add ARM_SMMU_OPT_MSIPOLL flag. on the other hand, we only need to check
    a bit in options rather than two bits in features

Barry Song (3):
  iommu/arm-smmu-v3: replace symbolic permissions by octal permissions
    for module parameter
  iommu/arm-smmu-v3: replace module_param_named by module_param for
    disable_bypass
  iommu/arm-smmu-v3: permit users to disable msi polling
