diff to v2:
- Rebased as new capabilities and capabilities files were added since v2
- Replaced imaginary QEMU commit $HASH with actual commit hash (QEMU
  part was merged meanwhile)
- Worked in Peter's review of v2

Michal Prívozník (2):
  qemu_capabilities: Introduce
    QEMU_CAPS_X_USE_CANONICAL_PATH_FOR_RAMBLOCK_ID
  qemu: Do not Use canonical path for system memory
