    [PATCH] x86-64: Extend bzImage protocol for relocatable bzImage
    o Extend the bzImage protocol (same as i386) to allow bzImage loaders to
      load the protected mode kernel at non-1MB address. Now protected mode
      component is relocatable and can be loaded at non-1MB addresses.
    o As of today kdump uses it to run a second kernel from a reserved memory
