Subject: linux-next: manual merge of the kvm tree with Linus' tree

Hi all,

Today's linux-next merge of the kvm tree got a conflict in
arch/x86/kvm/x86.c between commit
36cb93fd6b6bf7e9163a69a8bf20207aed5fea44 ("KVM: x86: Fix probable memory
leak of vcpu->arch.mce_banks") from Linus' tree and commit
kvm_arch_vcpu_uninit ("KVM: switch vcpu context to use SRCU") from the
kvm tree.

I fixed it up (I think ... see below) and can carry the fix for a while.
