    SubjectRe: [PATCH 1/2] kdump: Allow shrinking of kdump region to be overridden

    Unfortunately a ppc64 kernel requires a chunk of RMO memory. We would
    need the ability to specify multiple crashkernel regions - about 32MB
    in the RMO and the rest can be anywhere. That sounds pretty fragile for
    a user to configure successfully on the cmdline.

    Thats why the ppc64 crashkernel region begins mid way through the RMO
    region. It means both kernels get a chunk of RMO and we only have to
    deal with one crashkernel reservation in all the tools and
