[PATCH v6 4/6] arm64/kvm: add a userspace option to enable pointer authentication

2019-02-19 Thread Amit Daniel Kachhap
This feature will allow the KVM guest to allow the handling of pointer authentication instructions or to treat them as undefined if not set. It uses the existing vcpu API KVM_ARM_VCPU_INIT to supply this parameter instead of creating a new API. A new register is not created to pass this parameter
