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
