For kexec you will not need CONFIG_RELOCATABLE_KERNEL. But if you also
want to use kdump and use same bzImage as first kernel then you will

For kdump I had done two presentations at OLS. You might find little
bit of kexec details too.

Kdump: Smarter, Easier, Trustier

Kdump, a kexec based crash dumping mechanism.
