Rafal Jaworowski 530a5fb294 Improve checking whether an ARM VA has a valid mapping before performing cache ... sync. VIPT/PIPT caches need valid VA-PA mapping in PTE for a cache operation to succeed (unlike VIVT). Prior to this fix pmap was using l2pte_valid() for that check, but this is not sufficient as the function merely checks if a PTE exists (there can be existing but _invalid_ entries in the table). A new pmap_has_valid_mapping() routine is introduced to do this job right by checking proper PTE flags. Among other potential problems this cures coherency issues with L2 caches on MV-78100.
