These changes take advantage of the new capability added in
merge commit 00e4db51259a5f936fec1424b884f029479d3981
"Allow using computed metrics in calculating other metrics".
The net is a simplification of the expressions for a handful
of metrics, but no functional change.

Hi Paul,
I've synced perf and testing on a remote machine (not easy for me to
log into) I see failures in perf test "10.3: Parsing of PMU event
table metrics" like:
...
parsing metric: dfu_stall_cpi - dflong_stall_cpi
Parse event failed metric 'dfu_other_stall_cpi' id 'dflong_stall_cpi'
expr 'dfu_stall_cpi - dflong_stall_cpi'
Error string 'parser error' help '(null)'
Parse event failed metric 'dfu_other_stall_cpi' id 'dfu_stall_cpi'
expr 'dfu_stall_cpi - dflong_stall_cpi'
Error string 'parser error' help '(null)'
...
This may be that the test doesn't handle the metric in terms of metric
addition and so I'll look for a fix. I thought I'd send a heads up in
case you had already seen/addressed this. Is perf test on PowerPC
clean for you at the moment?
Thanks,
Ian

I see these errors as well (on 5.9-rc2). Each error seems to be for the
newer metrics that take advantage of the newer functionality, including
the metrics I changed recently, and Kajol's 24x7 and nest metrics.
Thanks for the heads up! I confess I had not seen the errors only because
I wasn't looking. :-/

No worries, if we create a similar Intel metric it will likely exhibit
a similar issue in the test. Arnaldo and I have wondered about having
an all architectures mode for jevents to make it easier to test cases
like this. As my PowerPC set up is a bit special it is great that
you've confirmed this isn't at fault :-) I'll try to get time to dig a
little further.
Thanks,
Ian
