commit 2400617da7eebf9167d71a46122828bc479d64c9 upstream. Split the current bounce buffering logic used with persistent grants into it's own option, and allow enabling it independently of persistent grants. This allows to reuse the same code paths to perform the bounce buffering required to avoid leaking contiguous data in shared pages not part of the request fragments. Reporting whether the backend is to be trusted can be done using a module parameter, or from the xenstore frontend path as set by the toolstack when adding the device. This is CVE-2022-33742, part of XSA-403.
