[PATCH] makedumpfile: s390x: Fix KVBASE to correct value for s390x arcitecture.

From: Mahesh Salgaonkar <mahesh at linux.vnet.ibm.com>

While excluding free pages from s390x dumps taken on LPAR, makedumpfile
fails to convert page address to pfn. The reason is, the memory for
mem_section structure is allocated below '_stext' and since KVBASE is
set to SYMBOL(_stext), the function is_kvaddr() fails and return NULL

Set KVBASE to KENRELBASE(0) for s390x architecture to fix this issue.
