[Xen-devel] [PATCH v2 0/10] iomem memory policy

[Stefano Stabellini <sstabellini@kernel.org>]

Hi all,

This series introduces a memory policy parameter for the iomem option,
so that we can map an iomem region into a guest as cacheable memory.

Then, this series fixes the way Xen handles reserved memory regions on
ARM: they should be mapped as normal memory, instead today they are
treated as device memory.

Cheers,

Stefano
