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
