this is added just to make sure that perf doesn't complain if and when a
kvm exit happens with a trap code as 0x0.

perf kvm can be used to analyze guest exit reasons. This support already
exists in x86. Hence, porting it to powerpc.

quot;perf kvm stat report"
does all the post processing of parsing the events captured and
classifying them according to their exit reasons (which are already
availabe in "trace_book3s.h"). Similar method is used with hcall
analysis.
Thanks,
Hemant Kumar
nts, use:
# perf kvm stat report
or
# perf kvm stat report --event=vmexit
This should show the exit events along with the exit reasons.
The second patch in this series adds support to show the hcall events too with:
# perf kvm stat report --event=syscall
