[S390] topology: export cpu topology via proc/sysinfo
Export the cpu configuration topology via sysinfo. Two new lines are introduced: CPU Topology HW: 0 0 0 4 6 4 CPU Topology SW: 0 0 0 0 4 24 The HW line describes the cpu topology nesting levels when the maximum nesting level is used to get the corresponding SYSIB. The SW line describes what Linux is actually using. In this case it supports only two levels (CONFIG_SCHED_BOOK off) and therefore the hardware folded the two lower levels in the SYSIB response block.
