**Intel Kernel Issue** 
[#I596BF](https://gitee.com/openeuler/intel-kernel/issues/I596BF)

**Test:** 
With this patch set:

```
        \# perf stat -e L1-dcache-load-misses -- sleep 1
        
         Performance counter stats for 'sleep 1':
        
                    10,134      L1-dcache-load-misses
        
               1.000727264 seconds time elapsed
        
               0.000584000 seconds user
               0.000000000 seconds sys
```

Without this patch set, it returns event "not supported":

```
        # perf stat -e L1-dcache-load-misses -- sleep 1
        
         Performance counter stats for 'sleep 1':
        
           <not supported>      L1-dcache-load-misses
        
               1.001434664 seconds time elapsed
        
               0.000000000 seconds user
               0.001318000 seconds sys
```
