As discussed in the patch[1], this series adds the host statistics for traps that are redirected to the guest. Since there are 1-1 mapping for firmware counters as well, this series enables those so that the guest can collect information about these exits via perf if required. I have included the patch[1] as well in this series as it has not been applied and there will be likely conflicts while merging both.
