    kernel - Change IPI recovery watchdog
    * Change the default recovery watchdog timeout for IPIs from 1/16 second
      to 2 seconds and the repeated timeout from 1/2 second to 2 seconds.
    * Add missing initialization to pmap_inval_smp_cmpset(), without it an
      improper watchdog timeout/retry could occur.
    * This still may not fix issues with VMs when core threads cause extreme
      latencies on the host.
