[GIT pull] range hrtimers for .28

[Thomas Gleixner]

Linus,

please pull range-hrtimers from

  git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git v28-range-hrtimers-for-linus

These patches provide the following new functionality:

    - convert select/poll to hrtimers
    - introduce range_hrtimers which allow to apply slack on an hrtimer
      in order to allow batching of hrtimers
    - add a prctrl to modify the per process slack value
    - convert the user space interfaces to use the range(slack) interfaces

a detailed description is available here: http://lwn.net/Articles/296578/

Full patch is available from: http://userweb.kernel.org/~tglx/v28-range-hrtimers-for-linus.patch

Thanks,

        tglx
