[Qemu-devel] [PATCH v3 0/3] Introduce IOMMUNotifier struct

[Peter Xu]

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. Thanks,

Peter Xu (3):
  memory: introduce IOMMUNotifier and its caps
  memory: generalize iommu_ops.notify_started to notifier_add
  intel_iommu: allow invalidation typed notifiers
