* Force no inline, so we get a non-trivial jump. Use
* a hack to turn on no inline.
* IMPORTANT: This module should be compiled without
* optimizations (see Makefile in this directory).
* Otherwise, some things will be optimized away and
* we won't fully test the code.
* You may want to inspect the .ko before running with
* objdump -d.
* NOTE: If you disassemble the .ko, you will notice
* callq's that are not patched to jump to the correct
* place (e.g., they just jump to the next instruction).
* This is not an error. The module loading code
* patches these calls so that they work when the module
* is loaded. You can look at the relocation info in the
* .ko elf file with readelf -a.
