[kvm-ppc-devel] [PATCH] kvmppc: account guest time

[ehrhardt@linux.vnet.ibm.com]

From: Developer <developer@de.ibm.com>

This adds the support to account the guest and the host apart from each other.
It uses the already available structure&flags PF_VCPU reported in /proc/stat
and the kvm_guest_enter/exit already available in kvm_host.h.
After that patch the data is available in the proc file system. We will need
contributions to the userspace tools e.g. that read from there to bring that
feature to the end customer.
