    Subject[PATCH v2 10/11] ARC: enable platform specific mem_service implementation
    Date
    From: Noam Camus <noamca@mellanox.com>

    For User Mode Memory Bus Error some platforms do not creat interrupt
    level 2 e.g. nps400 creates machine check exception.
    Turning mem_service into weak symbol allows each platform to override
    mem_service with its own implementation.
