KVM: remember position in kvm->vcpus array
commit 8750e72a upstream. Fetching an index for any vcpu in kvm->vcpus array by traversing the entire array everytime is costly. This patch remembers the position of each vcpu in kvm->vcpus array by storing it in vcpus_idx under kvm_vcpu structure. Signed-off-by:Radim Krčmář <rkrcmar@redhat.com> Signed-off-by:
