[Xen-devel] [PATCH v4 0/6] iomem memory policy

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

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.

(Other things related to reserved-memory on Arm have been sent
separately.)

Cheers,

Stefano
