From: Mahesh Salgaonkar <mahesh@xxxxxxxxxxxxxxxxxx>
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
address.
Set KVBASE to KENRELBASE(0) for s390x architecture to fix this issue.
