FC7 kernel not best confugured for kdump

[Richard J Moore]

I've been checking out kdump on FC7. There are a couple of kernel config 
options cause the crash utility some issues.
These are CONFIG_PHYSICAL_ALIGN=4MB and CONFIG_PHYSICAL_START=16MB.

When the values differ on a reclocatable kernel we loose the ability to 
make line number references to the code addresses (vmlinux will have line 
numbers relative to START, kallsyms will reflect ALIGN). This wouldn't be 
the case if ALIGN and START were both 16MB. Is there is advantage in not 
doing that? 
 If there isn't can we make a point of building future release kernels 
with the two values equal?
