 * These are various utility functions of the scheduler,
 * built in a single compilation unit for build efficiency reasons.
 *
 * ( Incidentally, the size of the compilation unit is roughly
 *   comparable to core.c, fair.c, smp.c and policy.c, the other
 *   big compilation units. This helps balance build time, while
 *   coalescing source files to amortize header inclusion
 *   cost. )
