Pull KVM updates from Paolo Bonzini: "At over 200 commits, covering almost all supported architectures, this 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" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (203 commits) KVM: add missing cleanup_srcu_struct KVM: PPC: Book3S PR: Rework SLB switching code KVM: PPC: Book3S PR: Use SLB entry 0 KVM: PPC: Book3S HV: Fix machine check delivery to guest KVM: PPC: Book3S HV: Work around POWER8 performance monitor bugs KVM: PPC: Book3S HV: Make sure we don't miss dirty pages KVM: PPC: Book3S HV: Fix dirty map for hugepages KVM: PPC: Book3S HV: Put huge-page HPTEs in rmap chain for base address KVM: PPC: Book3S HV: Fix check for running inside guest in global_invalidates() KVM: PPC: Book3S: Move KVM_REG_PPC_WORT to an unused register number KVM: PPC: Book3S: Add ONE_REG register names that were missed KVM: PPC: Add CAP to indicate hcall fixes KVM: PPC: MPIC: Reset IRQ source private members KVM: PPC: Graciously fail broken LE hypercalls PPC: ePAPR: Fix hypercall on LE guest KVM: PPC: BOOK3S: Remove open coded make_dsisr in alignment handler KVM: PPC: BOOK3S: Always use the saved DAR value PPC: KVM: Make NX bit available with magic page KVM: PPC: Disable NX for old magic page using guests KVM: PPC: BOOK3S: HV: Add mixed page-size support for guest ...

Patch queue for ppc - 2014-05-30 In this round we have a few nice gems. PR KVM gains initial POWER8 support as well as LE host awareness, ihe e500 targets can now properly run u-boot, LE guests now work with PR KVM including KVM hypercalls and HV KVM guests can now use huge pages. On top of this there are some bug fixes. Conflicts: include/uapi/linux/kvm.h

KVM: PPC: Book3S: Move KVM_REG_PPC_WORT to an unused register number

2014-05-30T12:26:28Z

Commit b005255e12a3 ("KVM: PPC: Book3S HV: Context-switch new POWER8 SPRs") added a definition of KVM_REG_PPC_WORT with the same register number as the existing KVM_REG_PPC_VRSAVE (though in fact the definitions are not identical because of the different register sizes.) For clarity, this moves KVM_REG_PPC_WORT to the next unused number, and also adds it to api.txt. Signed-off-by: Paul Mackerras Signed-off-by: Alexander Graf

KVM: PPC: Book3S: Add ONE_REG register names that were missed

2014-05-30T12:26:27Z

Commit 3b7834743f9 ("KVM: PPC: Book3S HV: Reserve POWER8 space in get/set_one_reg") added definitions for several KVM_REG_PPC_* symbols but missed adding some to api.txt. This adds them. Signed-off-by: Paul Mackerras Signed-off-by: Alexander Graf

KVM: PPC: Disable NX for old magic page using guests

2014-05-30T12:26:24Z

Old guests try to use the magic page, but map their trampoline code inside of an NX region. Since we can't fix those old kernels, try to detect whether the guest is sane or not. If not, just disable NX functionality in KVM so that old guests at least work at all. For newer guests, add a bit that we can set to keep NX functionality available. Signed-off-by: Alexander Graf

Merge tag 'kvm-arm-for-3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into kvm-next

2014-05-27T13:58:14Z

Changed for the 3.16 merge window. This includes KVM support for PSCI v0.2 and also includes generic Linux support for PSCI v0.2 (on hosts that advertise that feature via their DT), since the latter depends on headers introduced by the former. Finally there's a small patch from Marc that enables Cortex-A53 support.

KVM: s390: announce irqfd capability

2014-05-15T08:55:10Z

s390 has acquired irqfd support with commit "KVM: s390: irq routing for adapter interrupts" (84223598778ba08041f4297fda485df83414d57e) but failed to announce it. Let's fix that. Signed-off-by: Cornelia Huck Acked-by: Christian Borntraeger Signed-off-by: Christian Borntraeger

KVM: s390: Add clock comparator and CPU timer IRQ injection

2014-05-06T12:58:05Z

Add an interface to inject clock comparator and CPU timer interrupts into the guest. This is needed for handling the external interrupt interception. Signed-off-by: Thomas Huth Reviewed-by: David Hildenbrand Reviewed-by: Cornelia Huck Signed-off-by: Christian Borntraeger
