Hi, This patchset reorganizes the cpufreq code and preserves the file permissions of cpufreq-related per-cpu sysfs files across suspend/resume cycles, by performing a light-weight init/teardown in those paths.
Patches 1 - 4 reorganize the code and have no functional impact, and can go in as general cleanups as well. This reorganization builds a base that the rest of the patches will make use of. Patch 5 and 6 add a mechanism to perform light-weight init/tear-down of CPUs in the cpufreq subsystem and finally patch 7 uses it to preserve sysfs files across suspend/resume. All the patches apply on Rafael's bleeding-edge branch on linux-pm git tree[1]. Changes in v2: * Fixed a refcounting bug explained here: http://marc.info/?l=linux-kernel&m=137511192600806&w=2 * Addressed some suggestions about code reorganization received in v1. * Rebased on top of the bleeding-edge branch.
