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-...or-linus.patch

Thanks,

tglx
