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_
[v2,09/10] powerpc/64s: Wire up cpu_show_
[v2,08/10] powerpc/pseries: Use the security flags in pseries_
[v2,07/10] powerpc/powernv: Use the security flags in pnv_setup_
[v2,06/10] powerpc/64s: Enhance the information in cpu_show_meltdown() [v2,01/10] powerpc: Add security feature flags for Spectre/Meltdown
[v2,05/10] powerpc/64s: Move cpu_show_meltdown() [v2,01/10] powerpc: Add security feature flags for Spectre/Meltdown
[v2,04/10] powerpc/powernv: Set or clear security feature flags [v2,01/10] powerpc: Add security feature flags for Spectre/Meltdown
[v2,03/10] powerpc/pseries: Set or clear security feature flags [v2,01/10] powerpc: Add security feature flags for Spectre/Meltdown
[v2,02/10] powerpc/pseries: Add new H_GET_CPU_
[v2,01/10] powerpc: Add security feature flags for Spectre/Meltdown [v2,01/10] powerpc: Add security feature flags for Spectre/Meltdown

@Breno the changes in this patch set touch some of the same areas of code:
http:// patchwork. ozlabs. org/project/ linuxppc- dev/list/ ?series= 33861&state= *
[v3,5/5] rfi-flush: Call setup_rfi_flush() after LPM migration
[v3,4/5] rfi-flush: Differentiate enabled and patched flush types
[v3,3/5] rfi-flush: Always enable fallback flush on pseries
[v3,2/5] rfi-flush: Make it possible to call setup_rfi_flush() again
[v3,1/5] rfi-flush: Move the logic to avoid a redo into the debugfs code
Should we backport around those changes or are they also required?
