Subject: [PATCH 00/15] iommu: Move domain allocation into drivers

From: Joerg Roedel <jroedel@...e.de>

Hi,

here is patch-set to replace the existing domain_init and
domain_destroy iommu-ops with the new domain_alloc and
domain_free callbacks

The new callbacks move the allocation of iommu domains into
the iommu driver, allowing them to put a generic
iommu_domain struct into their own domain struct. This makes
domain handling in the drivers more cache efficient and
prepares the introduction of default domains in another
patch-set.

While at it, this patch-set also introduces domain types.
These are internal to the iommu core code for now, there are
three of them:

	* DMA-API domains
	* Identity mapped domains
	* Domains unmanaged by the iommu-core, used for
	  iommu-api so that the users can create their own
	  mappings

The patches have been compile tested for x86, ARM and PPC
and runtime tested on x86 (Intel VT-d and AMD IOMMU).

Please review.

Thanks,

	Joerg
