Vivek Goyal dd0ec16fa6 [PATCH] i386: Restore CONFIG_PHYSICAL_START option
o Relocatable bzImage support had got rid of CONFIG_PHYSICAL_START option
  thinking that now this option is not required as people can build a
  second kernel as relocatable and load it anywhere. So need of compiling
  the kernel for a custom address was gone. But Magnus uses vmlinux images
  for second kernel in Xen environment and he wants to continue to use
  it.

o Restoring the CONFIG_PHYSICAL_START option for the time being. I think
  down the line we can get rid of it.
