[PATCH v3 00/23] iommu: Further abstract iommu-pages

[Alejandro Jimenez]

>Improve the API to work directly on sizes instead of order, the drivers
> generally have HW specs and code paths that already have specific sizes.
> Pass those sizes down into the allocator to remove some boiler plate
> get_order() in drivers. This is cleanup to be ready for a possible sub
> page allocator some day.

> This is on github: https://github.com/jgunthorpe/linux/commits/iommu_pages
>
> v3:

Tested v3 on AMD Zen4 bare metal host, using v1/v2 page table formats. Ran host
kernel with iommu.passthrough=0. Launched KVM guest with large memory (512+ G)
and 16 VFs. No errors or warnings found.
