Hi Canonical,
There are some additional patches for Spectre and Meltdown that is
required on ppc64el. We would need to have them included on all Ubuntu
kernels.
This is the patch series:
[v2,10/10] powerpc/64s: Wire up cpu_show_spectre_v2() [v2,01/10] powerpc: Add
security feature flags for Spectre/Meltdown
[v2,09/10] powerpc/64s: Wire up cpu_show_spectre_v1() [v2,01/10] powerpc: Add
security feature flags for Spectre/Meltdown
[v2,08/10] powerpc/pseries: Use the security flags in pseries_setup_rfi_flush()
[v2,01/10] powerpc: Add security feature flags for Spectre/Meltdown
