We're starting to require the reservation lock for pinning, so wait until we have that. Update the selftests to handle this correctly, and ensure pin is called in live_hwsp_rollover_user() and mock_hwsp_freelist(). Changes since v1: - Fix NULL + XX arithmatic, use casts. (kbuild) Changes since v2: - Clear entire cacheline when pinning. Changes since v3: - CACHELINE_BYTES -> TIMELINE_SEQNO_BYTES.
