The CCI PMU is not a CPU PMU. As such the CCI PMU events can be initiate from any proocessor. Set the valid_cpus mask to indicate this.

Hi Tixy,

Please pick this patch - it is required for the Linaro kernels to be able to use CCI PMU.

Thanks, I've applied this patch to the ARM Landing Team tree, and it should appear in the main linux-linaro tree and daily builds shortly (possibly by tomorrow morning :-).

The patch is based on top of your integration-linux-vexpress branch.

Cheers, Punit
