V3: - use QLIST instead of embedding Notifier into IOMMUNotifier [Paolo] - fix a build error for ppc64-softmmu
The idea originates from one of Alex's reply: https://lists.gnu.org/archive/html/qemu-devel/2016-09/msg00254.html But after further discussions, it seems that only adding a simple type for notifier is not enough. This series introduced IOMMUNotifier struct to replace the old Notifier interface. Along with it, we can provide registration for one (or multiple) of the IOMMU notifications: - cache invalidations - entry changes This is a support material for Jason's vhost dmar patchset. Please read commit messages for detailed information.
