Export encrypts a secure guest's page and makes it accessible to the
guest for paging.
How does paging play along with pinning the pages (from
uv_convert_to_secure() -> kvm_s390_pv_pin_page()) in a follow up patch?
Can you paint me the bigger picture?
That's a stale comment I should have removed before sending...
The current patches do not support paging.
Note that once you pin you really have to disable the balloon in the
QEMU (inhibit it).
