Thanks Segher. You are right. I did not notice that.
Section Headers:
[Nr] Name Type Addr Off Size ES Flg Lk Inf Al
[ 0] NULL 00000000 000000 000000 00 0 0 0
[ 1] .text PROGBITS 00000000 000034 000044 00 AX 0 0 4
[ 2] .rel.text REL 00000000 0005c8 000040 08 8 1 4
[ 3] .data PROGBITS 00000000 000078 000000 00 WA 0 0 4
[ 4] .bss NOBITS 00000000 000078 001000 00 WA 0 0 4
[ 5] .text.head PROGBITS 00000000 000078 00006e 00 0 0 1
.text.head is not type AX so it will be left out from the linked output.
This reminds me that I have put another patch in kernel/head.S creating
a new section .text.head. I think I shall have to put a patch there too
to make it work with older binutils.
Thanks
