All relocation processing happens in the kernel itself.


Is it possible to decompress and extract the kernel image from the
bzImage without executing it? Ie, is there enough information to find
the compressed data part of the bzImage by inspection?

At some point we'll need to change the Xen domain builder to handle
bzImage files, and it would be best if we didn't need to run them.
