vmlinux extract the ELF relocatable
 

Hi,

I have a vmlinuz and vmlinux (not stripped) 64 bit kernel, without the support for module. I lost the original source, in this kernel there is a not official patch and I need to insert a new scsi driver. Is there a solution?
I extracted the ELF relocatable with objcopy and ld, but I lost the symbol.
Is there a way for recreate a vmlinux.o and link a new scsi driver compiled from source of kernel.org.
I see the project eresi but not support kernel to 64 bit.

Thank you
