Hi Hatayama,
/proc/vmcore ELF headers have virtual address information and using that you should be able to read actual value of phys_base. gdb deals with virtual addresses all the time and can read value of any symbol using those headers.
So I am not sure what's the need for exporting actual value of phys_base.
Thanks Vivek
