Hi,

As of now the kdump kernel base is fixed to be 32MB. The intention of 
this patch is to modify that behaviour (for relocatable kernels)

* Regular kernel size may exceed 32MB, in this case we can't have kdump 
kernelbase as 32MB.

* crashkernel=auto also assumes that kdump kernelbase as 32MB, and it 
may also fail in reserving memory for kdump kernel.

I'm not opposed to remove the 32MB restriction, but I would like to make
the behaviour independent of CONFIG_RELOCATABLE like it's on x86:

 - Use 32M if one specifies xxx@32M
 - Use preferrably 32M, but fall back to another address if one
   specifies xxx or xxx@0M.

I don't see any problem with that. But it would make behaviour equal
accross platforms.

Bernhard
