Michael Roth 46add0349b KVM: x86: fix CPUID entries returned by KVM_GET_CPUID2 ioctl ... commit 181f494888d5b178ffda41bed965f187d5e5c432 upstream. Recent commit 255cbecfe0 modified struct kvm_vcpu_arch to make 'cpuid_entries' a pointer to an array of kvm_cpuid_entry2 entries rather than embedding the array in the struct. KVM_SET_CPUID and KVM_SET_CPUID2 were updated accordingly, but KVM_GET_CPUID2 was missed. As a result, KVM_GET_CPUID2 currently returns random fields from struct kvm_vcpu_arch to userspace rather than the expected CPUID values. Fix this by treating 'cpuid_entries' as a pointer when copying its contents to userspace buffer.
