    sparc: refactor code in fault_32.c · 0157141a
    Sam Ravnborg 提交于
    The sparc allmodconfig build broke due to enabling of the
    branch_tracer that does some very clever things with
    all if conditions. This caused my gcc 3.4.5 to be so confused that
    it emitted a warning:
    
    arch/sparc/mm/fault_32.c: In function `do_sparc_fault':
    arch/sparc/mm/fault_32.c:176: warning: 'fixup' might be used uninitialized in this function
    
    And with -Werror this broke the build.
    
    Refactor code so it:
    1) becomes more readable
    2) no longer emit a warning with the branch_tracer enabled
