    [SPARC]: Fix several regset and ptrace bugs. · d786a4a6
    David S. Miller authored
    1) ptrace should pass 'current' to task_user_regset_view()
    
    2) When fetching general registers using a 64-bit view, and
       the target is 32-bit, we have to convert.
    
    3) Skip the whole register window get/set code block if
       the user isn't asking to access anything in there.
    
       Otherwise we have problems if the user doesn't have
       an address space setup.  Fetching ptrace register is
       still valid at such a time, and ptrace does not try
       to access the register window area of the regset.
