[PATCH 0/2] support device init for balloon pages

Once a page gets out of balloon (on deflate, or on access for
reporting) the Linux guest inits it before giving it to app.
It's a waste - the page is already inited by the host.

Add balloon support for skipping that, that provides significant
performance gains:
