RT PREEMPT patches?

Has anybody tried applying RT PREEMPT patches (http://rt.wiki.kernel.org/) to Nios II Linux?

Hi,

Normal CONFIG_PREEMPT is working fine (of course, I don't know its efficiency). This configuration avoids the critical sections by only disabling the interruptions.

For CONFIG_PREEMPT_RT, you need not only to apply the patches but to make Nios's machine dependent codes which are very similar for SMP systems.
