bitkeeper revision 1.1713.1.13 (42b16610ojQcHPRC6Ao_1CKXClza9A)
Slightly disgusting hack to avoid using lots of lock instructions on a uniprocessor machine just because we happened to compile with CONFIG_SMP. Essentially, we make a big table of all of the instruction sequences which differ in ``easy'' ways between UP and SMP kernels, and then select which one to use at run time.
