  • cpuidle
    • Discussion about ack and review tags in the patches and who is the maintainer of the cpuidle core. Rafael J. Wysocki is the maitainer, should be copied on the patches. Another suggestion is to copy Andrew Morton directly.

  • Common Clock
    • Work is done it will be either in 3.4 or Linux-next

  • Exynos Common Store/restore will be merged in 3.4
  • blueprints review
    • Focus of this month is to handle cpuidle common code and all platforms cpuidle drivers.
    • If it cannot be merged, will create a topic branch for all cpuidle work and and give it to linaro-kernel to merge.
    • Thermal Durgadon from intel provided some good feedback, Amit will update accordingly.
    • work is pretty much done, completing all requirements, what is left is update based on
