One more ifdef to rescue..
Btw, do you know why we only play these mark clean bits for swiotlb
and not for the various iommus?
Also do you have any good receipe to build an ia64 cross compiler on
a recent Debian system? Unlike most architectures Debian doesn't have
a pre-built one, and the

Instead of providing a special dma_mark_clean hook just for ia64, switch
ia64 to use the normal arch_sync_dma_for_cpu hooks instead.
This means that we now also set the PG_arch_1 bit for pages in the
