So someone tried for me on Debian 4.9.82-1+deb9u2 on this hardware:

processor       : 0
cpu             : POWER8E (raw), altivec supported
clock           : 3425.000000MHz
revision        : 2.1 (pvr 004b 0201)

we have:
/sys/devices/system/cpu/vulnerabilities/meltdown:Mitigation: RFI Flush

Does this mean it's correctly enabled or do we still miss the various patches
sent by Michael?
