2802	  is properly shutdown, so do not be surprised if this code does not

2854	  32-bit MIPS systems this support is at the cost of increasing the

2856	  running a MIPS32 system and know that none of your userland binaries
2857	  will require 64-bit floating point, you may wish to reduce the size
2858	  of your kernel & potentially improve FP emulation performance by
