Subject: kernel build failures with gcc 3.3.3 and newer, Inconsistent kallsyms data, try setting CONFIG_KALLSYMS_EXTRA_PASS

linux-2.6.7-bk16 has a new kallsyms check. This check fails with gcc
newer than 3.3.2. It passes with 3.4.1 and the hammer branch.

all symbols are 0x10 off with gcc 3.3.3, like:

 diff -u System.map .tmp_System.map |  grep tcp_hashinfo
-c032f4e0 D tcp_hashinfo
+c032f500 D tcp_hashinfo

the intial nm -n output has only these differences:

 cut -b 10- gcc332/nm-m-.tmp_vmlinux1 > 2.o
 cut -b 10- gcc333/nm-m-.tmp_vmlinux1 > 3.o
 diff -u 2.o 3.o
