Thanks for the review, I carefully modified all the patch commit 
messages
to change the config and wording from CONFIG_EXCLUDE_KERNEL_HW_ITRACE to
CONFIG_EXCLUDE_KERNEL_PMU_TRACE but missed this commit message. I will
fix this up in v3, but will hold off posting v3 till I get some feedback
on other patches.

Thanks,
Sai
