The first pull request for the Xen virtualization updates for the Linux 3.16 kernel
have now been submitted.
David Vrabel sent in the early Xen features and fixes this morning for the Linux 3.16 merge window. Most prominently to Xen in Linux 3.16 are ARM architecture improvements. In particular, there's now ARM suspend/resume support and ARM multi-call support.
Other changes include support for foreign mappings in PVH domains and fixing for mapping high MMIO regions for x86 PV guests.
The other initial Xen changes for Linux 3.16 can be found via the pull request
