was a pretty active cycle for KVM. Changes include: - a lot of s390 changes: optimizations, support for migration, GDB support and more - ARM changes are pretty small: support for the PSCI 0.2 hypercall interface on both the guest and the host (the latter acked by Catalin) - initial POWER8 and little-endian host support - support for running u-boot on embedded POWER targets - pretty large changes to MIPS too, completing the userspace interface and improving the handling of virtualized timer hardware - for x86, a larger set of changes is scheduled for 3.17. Still, we have a few emulator bugfixes and support for running nested fully-virtualized Xen guests (para-virtualized Xen guests have always worked). And some optimizations too. The only missing architecture here is ia64. It's not a coincidence that support for KVM on ia64 is scheduled for removal in 3.17. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAABAgAGBQJTjtlBAAoJEBvWZb6bTYbyMOUP/2NAePghE3IjG99ikHFdn+BX BfrURsuR6GD0AhYQnBidBmpFbAmN/LwSJxv/M7sV7OBRWLu3qbt69DrPTU2e/FK1 j9q25peu8jRyHzJ1q9rBroo74nD9lQYuVr3uXNxxcg0DRnw14JHGlM3y8LDEknO8 W+gpWTeAQ+2AuOX98MpRbCRMuzziCSv5bP5FhBVnsWHiZfvMbcUrbeJt+zYSiDAZ 0tHm/5dFKzfj/vVrrnjD4EZcRr688Bs5rztG96hY6aoVJryjZGLtLp92wCWkRRmH CCvZwd245NmNthuKHzcs27/duSWfU0uOlu7AMrD44QYhzeDGyB/2nbCxbGqLLoBA nnOviXH4cC65/CnisZ79zfo979HbZcX+Lzg747EjBgCSxJmLlwgiG8yXtDvk5otB TH6GUeGDiEEPj//JD3XtgSz0sF2NvjREWRyemjDMvhz6JC/bLytXKb3sn+NXSj8m ujzF9eQoa4qKDcBL4IQYGTJ4z5nY3Pd68dHFIPHB7n82OxFLSQUBKxXw8/1fb5og VVb8PL4GOcmakQlAKtTMlFPmuy4bbL2r/2iV5xJiOZKmXIu8Hs1JezBE3SFAltbl 3cAGwSM9/dDkKxUbTFblyOE9bkKbg4WYmq0LkdzsPEomb3IZWntOT25rYnX+LrBz bAknaZpPiOrW11Et1htY =j5Od -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm into next Pull KVM updates from Paolo Bonzini: "At over 200 commits, covering almost all supported architectures, this was a pretty active cycle for KVM.
