Would you mind to revisit the following patches for upstream ?

For vPMU, please review two more patches as well:
+ 
https://lore.kernel.org/kvm/20191030164418.2957-1-like.xu@linux.intel.com/ 
(kvm)
+ 
https://lore.kernel.org/lkml/20191105140955.22504-1-like.xu@linux.intel.com/ 
(perf)

Thanks,
Like Xu
