[Xen-devel] [PATCH 0/3] TLB flushing and IO memory mapping



This patch set resolves an issue with TLB flushing on grant unmapping
that had in the past prevented grant map operations being performed by
domains without hardware access.  It then removes the restriction on the
grant operations, and provides the ability to give IO memory permissions
from dom0 into a guest using the grant tables.

Most of these patches have been posted before, and I don't think they
have been modified since, but seemed like a good time to push them
again.  They've been used extensively by us for some months without any
known problems.

1/3: Fix TLB flush on grant unmap

2/3: Make grant operations permitted now TLB flushing issue solved

3/3: Allow iomem permissions to be set up through grant table ops

It would be very helpful if these could be applied to xen-unstable.hg.
