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 patch=
es
sent by Michael?
