arch/arm: Fix missing define for ARM_PMU_DEVICE_CPU

From: Peter Huewe <[email protected]>

This patch adds a define for ARM_PMU_DEVICE_CPU which seemed to be missing/undefined and caused some build failures [1-4].

I defined ARM_PMU_DEVICE_CPU = -1 as stated in Documentation/driver_model/platform.txt to indicate there is only one. I'm _not_ sure if this is correct, but due to the static nature of the define I assume it is.

Hi Peter,

This build error is due to the core patch of Will's "ARM: pmu: provide a registration mechanism for IRQs" patch series not being merged yet. I'm not sure what the status of that patch is at the moment though.

Hi Jamie,

Thanks for CC'ing me on this.

I submitted the series to Russell's patch system on 9 April. However, as you know, he's currently without an internet connection and the patch system has gone offline. He applied some of the series before he lost connectivity, so I expect he'll look at the others when he's back [although I imagine there are lots of other patches in the same situation].

Peter: if you're interested, the patch series I sent to the ARM Linux list is archived here:

Cheers,

Will

Ah, didn't know about this - then sorry to 'bug' you with my patch :)

Thanks for the Link - I'll have a look at it.

Thanks,
