[PATCH v1 0/4] KVM: arm64: Fixes to handling of restricted registers for protected VMs

[Fuad Tabba <tabba@google.com>]

This patch series is mainly about fixing 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 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.

Based on Linux 6.16.

Cheers,
