    KVM: arm64: Add capability to advertise ptrauth for guest · a243c16d
    Amit Daniel Kachhap authored
    This patch advertises the capability of two cpu feature called address
    pointer authentication and generic pointer authentication. These
    capabilities depend upon system support for pointer authentication and
    VHE mode.
    
    The current arm64 KVM partially implements pointer authentication and
    support of address/generic authentication are tied together. However,
    separate ABI requirements for both of them is added so that any future
    isolated implementation will not require any ABI changes.
