 this change includes this diff:
 
 -       emergva = uvm_km_alloc(kernel_map, round_page(MAXPHYS), 0,
 +       emergva = uvm_km_alloc(kernel_map,
 +           round_page(MAXPHYS) + ptoa(uvmexp.ncolors), 0,
 
 however, there's no accounting for if uvm_page_recolor() is ever called
 like it is on x86, ppc and sparc64, so later if using this space we're
 going to trash on someone else's memory.
