6.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Niklas Schnelle <schnelle@xxxxxxxxxxxxx>
[ Upstream commit 4181b51c38875de9f6f11248fa0bcf3246c19c82 ]
In commit 4e4dc65ab578 ("s390/pci: use phys_to_virt() for AIBVs/DIBVs")
the setting of dibv_addr was missed when adding virt_to_phys(). This
only affects systems with directed interrupt delivery enabled which are
not generally available.
