Hi maintainers,

Just to add some context, I reproduced this issue on an arm64 platform.

Without this patch, "perf list" reports:

   idle-cycles-frontend
        [Stalled cycles during issue [This event is an alias of
         stalled-cycles-fronted]. Unit: armv8_pmuv3]

But there is no "stalled-cycles-fronted" event. The intended event name 
is "stalled-cycles-frontend".

After the fix, the description points to the correct event name.

Thanks,
Pu Hu
