Your comment isn't what I meant. What I meant is that if the process is context switched while walking the page tables, the low level powerpc context switch code should also perform a __flush_tlb_pending. BTW. Is the pte_lock also not a real spinlock anymore ? That may break other assumptions the powerpc mm code is doing. This -rt stuff is just too scary, it changes some fundamental semantics of the spinlocks. yuck.
