This looks better to me, so I took it for a spin on my 4460 (thanks Nicolas!)
and noticed that only the cycle counter seems to tick -- the event counters
always return 0 deltas (that is, they don't increment). Booting the same SD
card on a 4430 (same MLO, u-boot, kernel and filesystem) I see that the
event counters function correctly there.

It also seems that we can remove the dependency on CONFIG_OMAP3_EMU with these
patches but I don't have any OMAP3 hardware to check if we get any regressions
on older platforms. Do your patches only deal with OMAP4?
