    Subject[PATCH 4.4 099/108] alpha: fix reboot on Avanti platform
    Date
    4.4-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Mikulas Patocka <mpatocka@redhat.com>

    commit 55fc633c41a08ce9244ff5f528f420b16b1e04d6 upstream.

    We need to define NEED_SRM_SAVE_RESTORE on the Avanti, otherwise we get
    machine check exception when attempting to reboot the machine.
