Another relocation oddness

[Petr Machata <pmachata at redhat dot com>]

Hi,

In this file:
kernel-debuginfo-2.6.29-0.258.rc8.git2.fc11.i586:usr:lib:debug:lib:modules:2.6.29-0.258.rc8.git2.fc11.i586:vmlinux

I'm seeing relocations that seem wrong: the addend and the value of the 
symbol the relocation is done against are the same.

Relocation section [71] '.rel.debug_aranges' for section [70] 
'.debug_aranges' at offset 0x4d1d0dc contains 4309 entries:
   Offset      Type                 Value       Name
   0x00000006  386_32               0000000000  .debug_info
   0x00000010  386_32               0xc0400000  .text.head

Section Headers:
[Nr] Name           Type     Addr     Off     Size   ES Flags Lk Inf Al
[ 0]                NULL     00000000 000000  000000 0        0  0   0

[ 2] .rel.text.head REL      00000000 4b3313c 0001e0 8        87 1   4
[ 3] .text          PROGBITS c0400400 001400  2f33ca 0  AX    0  0   128

Symbol table [87] '.symtab' contains 40473 entries:
  29807 local symbols  String table: [88] '.strtab'
   Num:    Value   Size Type    Bind   Vis          Ndx Name
     0: 00000000      0 NOTYPE  LOCAL  DEFAULT    UNDEF
     1: c0400000      0 SECTION LOCAL  DEFAULT        1
     2: c0400400      0 SECTION LOCAL  DEFAULT        3
     3: c06f37cc      0 SECTION LOCAL  DEFAULT        5

And objdump just to be sure:
Contents of section .debug_aranges:
  0000 1c000000 02000000 00000400 00000000  ................
  0010 000040c0 b1030000 00000000 00000000  ..(a).............
  0020 1c000000 02007d00 00000400 00000000  ......}.........

Unless I'm wrong here, what I see is relocation with addend 0xc0400000, 
formed against .text.head, whose address also is 0xc0400000, resulting 
in relocated address 0x180800000, or 0x80800000 after 32-bit wrapping 
(which I made up right now, dwarflint forgets to do this).  That doesn't 
fall into any section.  Bug, or am I missing something?
