This is equivalent to defining elfcorehdr_addr under CONFIG_CRASH_DUMP instead of CONFIG_PROC_VMCORE. This is needed by is_kdump_kernel() which can be used irrespective of the fact whether CONFIG_PROC_VMCORE is enabled or not. o I don't see sh setup code parsing the command line for elfcorehdr_addr. I am wondering how does vmcore interface work on sh. Anyway, I am atleast defining elfcoredhr_addr so that compilation is not broken on sh.
