[PATCH v2 0/7] rework sched_domain topology description

From: Vincent Guittot
Date: Tue Mar 18 2014 - 13:59:51 EST

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.

[2] https://lkml.org/lkml/2013/11/5/239
[3] https://lkml.org/lkml/2013/11/5/449

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

Vincent Guittot (7):
sched: remove unused SCHED_INIT_NODE
sched: rework of sched_domain topology definition
sched: s390: create a dedicated topology table
sched: powerpc: create a dedicated topology table
sched: add a new SD_SHARE_POWERDOMAIN for sched_domain
sched: ARM: create a dedicated scheduler topology table
sched: powerpc: Add SD_SHARE_POWERDOMAIN for SMT level
