From 2af1acadc22e86b9fff7b2cd73ea9c779ba1a065 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 25 May 2018 14:27:53 +0100 Subject: target/i386/kvm.c: Handle renaming of KVM_HINTS_DEDICATED In kernel header commit 633711e8287, the define KVM_HINTS_DEDICATED was renamed to KVM_HINTS_REALTIME. Work around this compatibility break by (a) using the new constant name, and (b) defining it if the headers don't. Part (b) can be removed once we've updated our copy of the kernel headers to a version that defines KVM_HINTS_REALTIME.
