[PATCH v2 0/3] KVM: arm64: Fixes to handling of restricted registers for protected VMs

[Fuad Tabba <tabba@google.com>]

This patch series mainly fixes issues we've encountered in pKVM (in
downstream Android code), related to the handling of protected VM access
to restricted registers and injecting undefined exceptions into a
protected guest.

The last patch in this series isn't pKVM specific, but a fix to the
vgic-v2 code encountered while fixing the issues in this series. The
issue it fixes was indirectly introduced into the code with hVHE.

Changes from v1 [1]:
- Dropped the refactoring patch.
- Added Reported-by tags.

Based on Linux 6.16.

Cheers,
