s390/cache: add cpu cache information to /proc/cpuinfo
Add a line for each cpu cache to /proc/cpuinfo. Since we only have information of private cpu caches in sysfs we add a line for each cpu cache in /proc/cpuinfo which will also contain information about shared caches. For a z196 machine /proc/cpuinfo now looks like: vendor_id : IBM/S390 bogomips per cpu: 14367.00 features : esan3 zarch stfle msa ldisp eimm dfp etf3eh highgprs cache0 : level=1 type=Data scope=Private size=64K line_size=256 associativity=4 cache1 : level=1 type=Instruction scope=Private size=128K line_size=256 associativity=8 cache2 : level=2 type=Unified scope=Private size=1536K line_size=256 associativity=12 cache3 : level=3 type=Unified scope=Shared size=24576K line_size=256 associativity=12 cache4 : level=4 type=Unified scope=Shared size=196608K line_size=256 associativity=24 processor 0: version = FF, identification = 000123, machine = 2817 processor 1: version = FF, identification = 100123, machine = 2817 processor 2: version = FF, identification = 200123, machine = 2817 processor 3: version = FF, identification = 200123, machine = 2817 Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
