Lars,
normally set_pte_at() is invoked in a
cache_flush_*() set_pte_at() tlb_flush_*()
sequence. So I'm wondering if you're trying to fix something in set_pte_at that actually ought to be fixed in the cache_flush_*() function.
I'm wondering, have you identified which cache flush function in particular was used in the sequence in your particular bug's case?
Ralf
