Summary

These are the low-level interface for Xen on ARM64. Not all of the
interface is included since we don't use all portions of Xen's API.

This was broken off of a "xen/arm64: add xen platform" commit. The
original commit was on the large side, and the hypercall code seemed
distinct from other portions.

A few small adjustments were needed from the original implementation in

Event Timeline

I had been expecting to manually flag this, but I see it has been setup to preemptively alert people.

That license does need checking. My reading is this falls under "when distributed separately from the Linux kernel or incorporated into other software packages, subject to the following license:"

This matches the license for sys/{amd64|i386}/include/xen/hypercall.h, so I believe this is acceptable.

Any news from the core team? I can well imagine license reviews taking a while, but since this matches existing files I would expect that to greatly simplify things.
