Yes, sure.

Did I understand the processor manual correctly that it is not possible
to retrieve a cached page of a user context we just evicted from the mmus
because the cpu will compare the physical address with the PA tag in the
cache? I.e. if the mmu does not find a valid PA, the cache will not be
used either?

In that case, at least this blast_dcache() and the one in pmap_remove()
could be removed, right?
