perf list: Fix s390 counter long description for L1D_RO_EXCL_WRITES
Command # perf list --long-desc pmu lists the long description of the available counters. For counter named L1D_RO_EXCL_WRITES on machine types 3906 and 3907 the long description contains the counter number 'Counter:128 Name:' prefix. This is wrong. The fix changes the description text and removes this prefix. Output before: [root@m35lp76 perf]# ./perf list --long-desc pmu ... L1D_ONDRAWER_L4_SOURCED_WRITES [A directory write to the Level-1 Data cache directory where the returned cache line was sourced from On-Drawer Level-4 cache] L1D_RO_EXCL_WRITES [Counter:128 Name:L1D_RO_EXCL_WRITES A directory write to the Level-1 Data cache where the line was originally in a Read-Only state in the cache but has been updated to be in the Exclusive state that allows stores to the cache line] ... Output after: [root@m35lp76 perf]# ./perf list --long-desc pmu ... L1D_ONDRAWER_L4_SOURCED_WRITES [A directory write to the Level-1 Data cache directory where the returned cache line was sourced from On-Drawer Level-4 cache] L1D_RO_EXCL_WRITES [L1D_RO_EXCL_WRITES A directory write to the Level-1 Data cache where the line was originally in a Read-Only state in the cache but has been updated to be in the Exclusive state that allows stores to the cache line] ...
