2.6.29-stable review patch. If anyone has any objections, please let us know. ------------------ From: Avi Kivity commit a4c0364be3f43d3e17fe19270f8b3d64881606e6 upstream. Under CONFIG_MAXSMP, cpus_hardware_enabled is allocated from the heap and not statically initialized. This causes a crash on reboot when kvm thinks vmx is enabled on random nonexistent cpus and accesses nonexistent percpu lists. Fix by explicitly clearing the variable.
