[Xen-devel] TLB flushing in x86's map_pages_to_xen()

While I realize that the local-flush-only approach attempts to minimize 
I have some difficulty understanding how this can properly deal with the effects
of speculation on remote processors. I believe this will get even worse when
considering cacheability changes, in which case it is not only an immediate TLB
flush that is needed, but also an immediate cache flush.

Thanks for any clarification, Jan
