Platforms subscribe into generic ptdump implementation via GENERIC_PTDUMP.
But generic ptdump gets enabled via PTDUMP_CORE. These configs combination
is confusing as they sound very similar and does not differentiate between
platform's feature subscription and feature enablement for ptdump. Rename
the configs as ARCH_HAS_PTDUMP and PTDUMP making it more clear and improve
readability.

I'd suggest dropp this from the defconfig too, just like patch 1 dropped
it from debug.config.

Thanks for spotting that.

That one is wrong. Was introduced by commit d210ee3fdfe8 ("powerpc/configs: Update config files for removed/renamed symbols") which aimed at fixing commit e084728393a5 ("powerpc/ptdump: Convert powerpc to GENERIC_PTDUMP") but it did it wrong.

It is CONFIG_PTDUMP_DEBUGFS that is wanted.

Should this replacement be done in the series or would you like it
to be handled in powerpc later ?

Yes I think you should do the replacement.
