    arm64: Define AT_VECTOR_SIZE_ARCH for ARCH_DLINFO · ec2ae4c8
    James Hogan authored
    commit 3146bc64 upstream.
    
    AT_VECTOR_SIZE_ARCH should be defined with the maximum number of
    NEW_AUX_ENT entries that ARCH_DLINFO can contain, but it wasn't defined
    for arm64 at all even though ARCH_DLINFO will contain one NEW_AUX_ENT
    for the VDSO address.
    
    This shouldn't be a problem as AT_VECTOR_SIZE_BASE includes space for
    AT_BASE_PLATFORM which arm64 doesn't use, but lets define it now and add
    the comment above ARCH_DLINFO as found in several other architectures to
    remind future modifiers of ARCH_DLINFO to keep AT_VECTOR_SIZE_ARCH up to
    date.
