Subject: Re: [PATCH v1 0/2] perf/kvm: perf-kvm-stat on powerpc

Hi Michael,

These patches were posted a month back. We don't have any review 
comments to handle at this time. Can you pull these patches to your tree?
Please, do let me know if you want me to rebase these patches to a 
different tree (like Arnaldo's/tip etc).
