    ARM: restart: remove poodle restart handler · 3f1517a7
    Russell King authored
    The poodle restart handler was added in 74617fb6 (3593/1: Add reboot
    and shutdown handlers for Zaurus handhelds), and at that time it was
    necessary to deal with the RCSR register.  This commit also forced all
    restarts to use the 'hard' restart method.
    
    In dc38e2ad (pxa: Fix RCSR handling), the RCSR handling was removed,
    leaving just the forcing to use a 'hard' restart.  As hard restarts are
    the default (in the absense of a reboot= command line argument), this
    seems pointless.  In any case, Richard Purdie says:

    So, lets remove the unnecessary interception and rely on the default
    restart mode.
