Comment 11 for bug 702999

It seems that the patch in http://lists.infradead.org/pipermail/linux-arm-kernel/2011-March/045283.html is going to fix the issue by enabling pmu events for omap4, which are routed from CTI. The patch attached is a version of the above with removal of some CTI register reads that cause hang in the initial phase of booting. The patch has been verified on Panda board and the profile data could be generated that are shown by opreport. Although, there is a lockdep warning "possible circular locking dependency detected" when "opcontrol --start" is called for the first time.
