From: Mahesh Salgaonkar <mahesh@xxxxxxxxxxxxxxxxxx>
On s390x, dump refiltering fails in get_machdep_info_s390x() function while
reading vmlist kernel symbol data. It fails in vaddr_to_paddr_s390x()
function while resolving vmlist kernel symbol address. Since the vmlist
kernel symbol address is not a vmalloc address, the function returns failure.
Fix the vaddr_to_paddr_s390x() function to translate non-vmalloc'ed
address into physical adddress.
