Subject: [PATCH v4-rebased 0/7] iommu: split mapping to page sizes as supported by the hardware

v3->v4:
- simplify splitter logic (Joerg)
- declare supported page-sizes in the iommu_ops, without extending iommu_register (Joerg)
- iommu_unmap should now return bytes too (Joerg)
- don't cache min_pgsize anymore (Joerg)
- handle cases when ->unmap() actually unmaps more than requested (Joerg)
- unroll iommu_unmap completely in case it fails (KyongHo)
- use size_t for size parameters (KyongHo)
- add a patch to remove the bytes->order->bytes conversion we had
- rabased to master branch of the iommu tree (Joerg)
  (and now rebased to 3.2-rc1)

v2->v3:
- s/KB/KiB/ (David W)

v1->v2:
- split to patches (by keeping the old code around until all drivers are converted) (Joerg)

Tested with OMAP4 (with rpmsg/remoteproc) and compile tested for X86-64.

Ohad Ben-Cohen (7):
  iommu/core: stop converting bytes to page order back and forth
  iommu/core: split mapping to page sizes as supported by the hardware
  iommu/omap: announce supported page sizes
  iommu/msm: announce supported page sizes
  iommu/amd: announce supported page sizes
  iommu/intel: announce supported page sizes
  iommu/core: remove the temporary pgsize settings
