Subject: [PATCH v7 0/2]  iommu/arm-smmu: hard iova_to_phys
Message-ID: <1414617220-21493-1-git-send-email-mitchelh@codeaurora.org>

This series introduces support for performing iova-to-phys translations via
the ARM SMMU hardware on supported implementations. We also make use of
some new generic macros for polling hardware registers.

v6..v7:

  - iopoll: no changes. resending series due to arm-smmu change.
  - arm-smmu: added missing lock and fixed physical address mask

v5..v6:

  - iopoll: use shift instead of divide
  - arm-smmu: no changes, resending series due to iopoll change.

v4..v5:

  - iopoll: Added support for other accessor functions
  - iopoll: Unified atomic and non-atomic interfaces
  - iopoll: Fixed erroneous `might_sleep'
  - arm-smmu: Lowered timeout and moved to new iopoll atomic interface

v3..v4:

  - Updated the iopoll commit message to reflect the patch better
  - Added locking around address translation op
  - Return 0 on iova_to_phys failure

v2..v3:

  - Removed unnecessary `dev_name's

v1..v2:

  - Renamed one of the iopoll macros to use the more standard `_atomic'
    suffix
  - Removed some convenience iopoll wrappers to encourage explicitness
