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

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.

This just removes unused DEBUG_FORCEDAC define in the IOMMU code.

Thanks! I really apprecate it.
I think that this is the root problem and the patch fixes it in the
right way. Please send this patch to [EMAIL PROTECTED] and a

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

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).

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

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.

Obviously this wasn't intended for CONFIG_BLOCK=n usage, so just move the
option back in to the block.
Caught with a randconfig on sh.
