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.

Hi Vincent,
given the discussion we had for v1-v3 and a short boot test of v4:
For patch 1/5, 4/5, 5/5 on ARM TC2 (heterogeneous dual socket w/o SMT
machine):
Reviewed-by: Dietmar Eggemann <dietmar.eggem...@arm.com>
Tested-by: Dietmar Eggemann <dietmar.eggem...@arm.com>
Cheers,

Change since v3:
- remove last patch which was adding SD_SHARE_POWER_DOMAIN for powerpc's SMT
level
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
