With this code, you get silent side-effects of enabling PPC_CELLEB
along with another platform.

  Yeah, thank you for pointing it out.
  I'll send revised patch later.

Maybe instead you should change the hpte_need_flush() to always flush
when running on the celleb platform and PREEMPT_RT is enabled.

  Hmm... Is it in linux-2.6.21?  grep'ing it did not help... 

  Is http://patchwork.ozlabs.org/linuxppc/patch?id=10361 is the first place
where the hpte_need_flush() appears?

Yes, I added that when reworking the batching mecanism.
