    Conflict: spec/kdump-lib_spec.sh doesn't exist in RHEL, so I remove
              the hunk directly.

        Allow _crashkernel_add to address larger memory ranges
    
        Currently _crashkernel_add can't deal with larger memory ranges like
        terabyte. For example, '_crashkernel_add "128G-1T:4G" "0"' actually
        returns empty result. This patch allows _crashkernel_add to address
        terabyte, petabyte and exabyte memory ranges.
