This patchset was previously part of the larger tasks packing patchset [1]. I have splitted the latter in 3 different patchsets (at least) to make the thing easier. -configuration of sched_domain topology (this patchset) -update and consolidation of cpu_power -tasks packing algorithm
Based on Peter Z's proposal [2][3], this patchset modifies the way to configure the sched_domain level in order to let architectures to add specific level like the current BOOK level or the proposed power gating level for ARM architecture.
