Heiko Carstens a759972d25 KVM: s390: fix sthyi error handling ... [ Upstream commit 0c02cc576e ] Commit 9fb6c9b3fe ("s390/sthyi: add cache to store hypervisor info") added cache handling for store hypervisor info. This also changed the possible return code for sthyi_fill(). Instead of only returning a condition code like the sthyi instruction would do, it can now also return a negative error value (-ENOMEM). handle_styhi() was not changed accordingly. In case of an error, the negative error value would incorrectly injected into the guest PSW. Add proper error handling to prevent this, and update the comment which describes the possible return values of sthyi_fill().
