The series is getting smaller, but you still included this patch
I pointed out in my last review, which unnecessary increases the
size of the initial hw support series by adding Haswell-specific
transaction profiling features.

As requested before, please keep those in a completely separate
series so that minimal support can be merged upstream. This is
how we always did new hardware support in the past, in iterative
steps, and we are not going to make an exception for you.

I find it pretty counterproductive that you have ignored my
previous series structure request. Every unnecessary delay you
cause here delays upstream profiling support for Haswell CPUs.

Thanks,

Ingo
