Hi,
Fedora and RHEL 7 use an unbundled libpfm rather than the one bundled with
PAPI. This power9 to allow the use of PM_LD_MISS_L1 and PM_ST_MISS_L1 at the
same time should be put into the upstream libpfm. -Will Cohen

Subject: [PATCH, papi 1/2] add power9 alternate events (papi)

[PATCH, papi] Add alternate event numbers for power9.
I had previously missed adding the _ALT entries, which allow some events to be
specified
on different counters. This fills those in.
