This doesn't\ndesperately matter for anything it currently does.\n\nHowever, SVE will need to know here whether the set of available\nvector lengths is fixed of still to be determined when booting a\nCPU so that it can be updated appropriately.\n\nThis patch simply moves the sys_caps_initialised stuff to the top\nof the file so that it can be more widely.
