    introduce-resume-exception-capture.patch
    
    This patch introduces a new resume debugging concept: if we
    get an OOPS inbetween starting suspend and finishing resume, it
    uses a new "emergency spew" device similar to BUT NOT REQUIRING
    CONFIG_DEBUG_LL to dump the syslog buffer and then the OOPS
    on the debug device defined by the existing CONFIG_DEBUG_S3C_UART
    index.  But neither CONFIG_DEBUG_LL nor the S3C low level configs
    are needed to use this feature.
    
    Another difference between this feature and CONFIG_DEBUG_LL is that
    it does not affect resume timing, ordering or UART traffic UNLESS
    there is an OOPS during resume.
    
    The patch adds three global exports, one to say if we are inside
    suspend / resume, and two callbacks for printk() to use to init
    and dump the emergency data.  The callbacks are set in s3c serial
    device init, but the whole structure is arch independent.
