[S390] Add VMCOREINFO_SYMBOL(high_memory) to vmcoreinfo
Currently the vmalloc_start address (or better end of real memory) for s390x is obtained by makedumpfile using vmlist.addr symbol, which is not correct. The correct vmalloc_start address can be obtained using 'high_memory' symbol. This patch adds the high_memory symbol to vmcoreinfo.
