Hi,
A couple of minor patches to print better PMU lacking overflow intr support such as in ARC700 cores.
This is an ABI change so might be controversial hence RFC.
Despite triviality, I've seperated the change into 2 pacthes - for different maintainers and also kept userspace change first to keep it bisectable.
Comments welcome !
Thx, -Vineet
