Not all PA CPUs have the U-bit (uncacheable) for non-IO memory. In fact
most don't. Deal with non-equivalent aliases by removing and flushing the managed mappings, and flushing the unmanaged mappings. When flushing caches/TLB flush the cache before purging the TLB just in case the flush enters the mapping into the TLB.
