Hi Andrii,

Here is a tree with all the backported Xen related patches:
git://xenbits.xen.org/people/aperard/linux-chromebook.git

Most of the commit from 95851ef3f08627307f86f77a7f99acbfff4d4470.. are
the one you will need, with few Exynos related.

But just in case, here is the list:

Also, the next two commit are fixing the GIC in the DT, so you will
maybe need something similair:
adba8c3 DEBUG Xen: have proper gic
21a3d8a fixup! DEBUG Xen: have proper gic


Hopefully, all those will be enough.

Have fun,
