Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull KVM updates from Paolo Bonzini: "Fixes and features for 3.18. Apart from the usual cleanups, here is the summary of new features: - s390 moves closer towards host large page support - PowerPC has improved support for debugging (both inside the guest and via gdbstub) and support for e6500 processors - ARM/ARM64 support read-only memory (which is necessary to put firmware in emulated NOR flash) - x86 has the usual emulator fixes and nested virtualization improvements (including improved Windows support on Intel and Jailhouse hypervisor support on AMD), adaptive PLE which helps overcommitting of huge guests. Also included are some patches that make KVM more friendly to memory hot-unplug, and fixes for rare caching bugs. Two patches have trivial mm/ parts that were acked by Rik and Andrew. Note: I will soon switch to a subkey for signing purposes" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (157 commits) kvm: do not handle APIC access page if in-kernel irqchip is not in use KVM: s390: count vcpu wakeups in stat.halt_wakeup KVM: s390/facilities: allow TOD-CLOCK steering facility bit KVM: PPC: BOOK3S: HV: CMA: Reserve cma region only in hypervisor mode arm/arm64: KVM: Report correct FSC for unsupported fault types arm/arm64: KVM: Fix VTTBR_BADDR_MASK and pgd alloc kvm: Fix kvm_get_page_retry_io __gup retval check arm/arm64: KVM: Fix set_clear_sgi_pend_reg offset kvm: x86: Unpin and remove kvm_arch->apic_access_page kvm: vmx: Implement set_apic_access_page_addr kvm: x86: Add request bit to reload APIC access page address kvm: Add arch specific mmu notifier for page invalidation kvm: Rename make_all_cpus_request() to kvm_make_all_cpus_request() and make it non-static kvm: Fix page ageing bugs kvm/x86/mmu: Pass gfn and level to rmapp callback. x86: kvm: use alternatives for VMCALL vs. VMMCALL if kernel text is read-only kvm: x86: use macros to compute bank MSRs KVM: x86: Remove debug assertion of non-PAE reserved bits kvm: don't take vcpu mutex for obviously invalid vcpu ioctls kvm: Faults which trigger IO release the mmap_sem ...
