Hi Mike,

With the above commit, kallsyms on ARM no longer show correct
information. That's a trace with this commit:

    [<c007bfec>] _etext+0xffd9bfec/0x126d8                                      
    [<c00795e4>] _etext+0xffd995e4/0x126d8                                      
    [<c0147d94>] _etext+0xffe67d94/0x126d8

    [<c007f250>] _etext+0xffd9f250/0x126d8

    [<c007c2b8>] _etext+0xffd9c2b8/0x126d8                                      
    [<c0023dc0>] _etext+0xffd43dc0/0x126d8                                      

and with the commit reverted:

Any idea what went wrong? I haven't looked at your commit in detail.

Thanks.
