IMHO, why break things if it's not necessary? As I understand it, you can still take the course of least resistance and implement 64-bit xen/kdump vmcores with 4-byte alignment -- and everybody's happy, right?
Unlike other tools that could potentially be broken, the crash utility will have to maintain backwards compatibility for all the other 4-byte aligned 64-bit vmcores out there. So to me, it's more a PITA than anything else, and I'll just adapt it to whatever's out there...
Thanks, Dave
