But\nbecause it is asynchronous with respect to loaded_vmcs_clear(), the vCPU\nmight migrate before the pointer is cleared and __loaded_vmcs_clear()\nmay then execute VMCLEAR.\n\nThe VMCS needs to stay attached until its explicit VMCLEAR completes, but\nthen it can be hidden and the page safely freed.",
