    kernel - Move CPUMASK_LOCK out of the cpumask_t
    
    * Add cpulock_t (a 32-bit integer on all platforms) and implement
      CPULOCK_EXCL as well as space for a counter.
    
    * Break-out CPUMASK_LOCK, add a new field to the pmap (pm_active_lock)
      and do the process vmm (p_vmm_cpulock) and implement the mmu interlock
      there.
    
      The VMM subsystem uses additional bits in cpulock_t as a mask counter
      for implementing its interlock.
    
      The PMAP subsystem just uses the CPULOCK_EXCL bit in pm_active_lock for
      its own interlock.
    
    * Max cpus on 64-bit systems is now 64 instead of 63.
    
    * cpumask_t is now just a pure cpu mask and no longer requires all-or-none
      atomic ops, just normal bit-for-bit atomic ops.  This will allow us to
      hopefully extend it past the 64-cpu limit soon.
