Subject: spapr_pci: parent the MSI memory region to the PHB
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=dba95ebbf88a8b8f10f4691946b4406e4acc4f0f;p=qemu.git

spapr_pci: parent the MSI memory region to the PHB

This memory region should be owned by the PHB. This ensures the PHB
cannot be finalized as long as the the region is guest visible, or
used by a CPU or a device.
