I finally ran down the problem. SAP is protecting the pages PROT_NONE, so the page-present bit in the pte is not set and canonicalize/uncanonicalize code in save/restore ignore the pte. I've attached a patch. It is possible that this change should be made to the l1e tests in xc_ptrace.c; I'm not sure.

The patch is against xen-unstable changeset 12815:1ad7dff99968.
