The Linux kernel famously scales from the smallest of systems to massive
servers with thousands of CPUs.  It was not always that way, though; the
initial version of the kernel could only manage a single processor.  That
limitation was lifted, obviously, but single-processor machines have always
been treated specially in the scheduler.  That longstanding situation may
soon come to an end, though, if this patch
series from Ingo Molnar makes it upstream.
