2.6.31-stable review patch. If anyone has any objections, please let us know. ------------------ From: Marcelo Tosatti commit eb5109e311b5152c0614a28d7d615d087f268f19 upstream. It is possible that stale EPTP-tagged mappings are used, if a vcpu migrates to a different pcpu. Set KVM_REQ_TLB_FLUSH in vmx_vcpu_load, when switching pcpus, which will invalidate both VPID and EPT mappings on the next vm-entry.
