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
