[PATCH v3 0/6] rework sched_domain topology description

[Vincent Guittot]

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.

Change since v2:
- remove patch 1 as it has been already applied to metag tree for v3.15
- updates some commit messages
- add new flag description in TOPOLOGY_SD_FLAGS description

Change since v1:
- move sched_domains_curr_level back under #ifdef CONFIG_NUMA
- use function pointer to set flag instead of a plain value.
- add list of tunable flags in the commit message of patch 2
- add SD_SHARE_POWER_DOMAIN flag for powerpc's SMT level
