    Subject[PATCH v5 09/10] ARM: export arm_pm_restart
    Date
    The OLPC XO 1.75 laptop is rebooted with a command to the Embedded
    Controller. The EC driver should be a module, since most people don't need
    it to be compiled in.

    The EC driver can't use register_restart_handler() because handlers
    registered with it are executed in atomic context and the XO 1.75 reboot
    dance needs to block: the reboot is initiated by poking a GPIO ofter
    which we need to wait for the EC to initiate a SPI transfer and finish
    it.
