In order to make the kernel boot faster, a set of patches were introduced by
Arjan van de Ven in January 2009
to create infrastructure to allow doing some of the initialization steps
asynchronously, which will hide significant portions of the hardware delays
in practice.

In order to not change device order and other similar observables, the
patch does NOT do full parallel initialization.

Rather, it operates more in the way an out of order CPU does; the work may
be done out of order and asynchronous, but the observable effects
(instruction retiring for the CPU) are still done in the original sequence.

See http://lkml.org/lkml/2009/1/4/155 for the first patch in the series.

Work similar in spirit to this was done previously, but with smaller
scope and apparently not mainlined.
