Subject: [PATCH v3 0/4] xen: add xen sysfs nodes

In order to be able to determine the Xen guest type from within the
guest as a user there is currently no stable interface available.

Add a sysfs node for that purpose as the guest type information is
available for the kernel.

While doing this document all the other Xen related sysfs nodes.

Add another node to show the Xen hypervisor buildid in order to make
hypervisor live patching easier.

Juergen Gross (4):
  doc,xen: document hypervisor sysfs nodes for xen
  xen: add sysfs node for guest type
  xen: sync include/xen/interface/version.h
  xen: add sysfs node for hypervisor build id
