Rebased onto linux-next.
This patch series introduces cpu frequency and power tracking for cpuacct cgroups. A similar patch set was discussed a while back and it was concluded that due to varying architectures (ppc, x86 with overboot) you cannot account for frequencies and their power consumption generically in sched.c, thus we have platform specific hooks the cpuacct can call into (if available).
I've implemented all the necessary hooks for OMAP architecture as an example. For the OMAP folks, I?m not sure what the state of the OPP API in mainline, as most of my original work was based off of the omap-pm branch.
