This just removes unused DEBUG_FORCEDAC define in the IOMMU code.

This patch makes the IOMMU code not allocate a memory area spanning
LLD's segment boundary.
is_span_boundary() judges whether a memory area spans LLD's segment
boundary. If iommu_arena_find_pages() finds such a area, it tries to
find the next available memory area.

The segment boundary limit should be a power of 2 so let's make it

This moves ch_template and changer_fops structs to the end of file and

This patch converts PPC's IOMMU to use the IOMMU helper functions. The
IOMMU doesn't allocate a memory area spanning LLD's segment boundary
anymore.
iseries_hv_alloc and iseries_hv_map don't have proper device
struct. 4GB boundary is used for them.

oundary of devices are set to 4GB by
default. So we can remove 4GB boundary protection now.

Yeah, I'll d
This patch makes swiotlb not allocate a memory area spanning LLD's
segment boundary.
is_span_boundary() judges whether a memory area spans LLD's segment
boundary. If map_single finds such a area, map_single tries to find
the next available memory area.

This is the latter half of my iommu work to make the IOMMUs respect
LLDs restrictions.
IOMMUs allocate memory areas without considering a low level driver's
segment boundary limits. So we have some workarounds: splitting sg
segments again in LLDs; reserving all I/O space spanning 4GB boundary
in I

the block layer and the scsi mid layer.

This adds PCI's accessor for segment_boundary_mask in
device_dma_parameters.
The default segment_boundary is set to 0x, same to the block
layer's default value (and the scsi mid layer uses the same value).

iova could be used by several IOMMUs. This patch just moves iova from
drivers/pci/ to lib/ and fixes the appropriate Makefile and Kconfig
files.

This converts the PPC64 IOMMU to use iova for free area management.
TODO: we might need to modify iova to use the tricks like avoiding
cacheline bouncing. Performance tests are necessary.

This patchset convert the PPC64 IOMMU to use the iova code for free
area management.
The IOMMUs ignores low level drivers' restrictions, the maximum
segment size and segment boundary.
I fixed the former:

This detaches iova cache code from intel-iommu.c to iova.c in order to

blk_rq_map_sg doesn't initialize sg->dma_address/length to zero
anymore. Some low level drivers reuse sg lists without initializing so
IOMMUs might get non-zero dma_address/length. If map_sg fails, we need
pass the number of the mapped entries to gart_unmap_sg.
