 .\" http://publibfi.boulder.ibm.com/epubs/pdf/dz9zr011.pdf
 The guarded storage facility is a hardware feature that allows marking up to
 64 memory regions (as of z14) as guarded;
-reading a pointer with a newly introduced "Load Guarded" (LGG) or "Load Logical
-and Shift Guarded" (LLGFSG) instructions will cause a range check on the loaded
-value and invoke a (previously set up) user-space handler if one of the guarded
-regions is affected.
