I understood. At most, get_mmu_context() will only do a 'tlbia' instruction, I didn't see your reason for thinking this would have an effect on the tlbie usage. >> Well, that's interesting.

With the larger TLB this is more likely to happen. The bug was never seen on the 823/850 with smaller TLBs. I have a new 8xx board now, so I'll have to start working on these issues as well.
