Re: [Xen-devel] [PATCH v2] xen: arm: Enable 1:1 workaround by default

Basically it is impossible to have a system which doesn't use the 1:1
map with 4.4 due to the lack of an iommu driver. Given this it is silly
to require every platform to enable this "quirk" and it's not
necessarily something which someone would think to enable when adding a
new platform, so it's just an unnecessary bear trap. (The down side of
not enabling 1:1 is weird I/O errors from dom0)

The patch is simple and low risk.

Sounds reasonable:
