parisc: Add CPU topology support
Add topology support, including multi-core scheduler support on PA8800/PA8900 CPUs and enhanced output in /proc/cpuinfo, e.g. lscpu now reports on a single-socket, dual-core machine: Architecture: parisc64 CPU(s): 2 On-line CPU(s) list: 0,1 Thread(s) per core: 1 Core(s) per socket: 2 Socket(s): 1 CPU family: PA-RISC 2.0 Model name: PA8800 (Mako) Signed-off-by: Helge Deller <deller@gmx.de>
