    kernel - Implement CPU localization hinting for low level page allocations
    
    * By default vm_page_alloc() and kmem_alloc*() localize to the calling cpu.
    
    * A cpu override may be passed in the flags to make these functions localize
      differently.
    
    * Currently implemented as a test only for the pcpu globaldata, idle
      thread, and stacks for kernel threads targetted to specific cpus.
