I think it's better if arm64_acpi_numa_init() and arm64_numa_init()
remained in the arm64 code. It's not really much code to be shared.
RISC-V will probably support ACPI one day. The idea is to not to do
exercise again in future.
Moreover, there will be arch_numa_init which will be used by RISC-V
and there will be arm64_numa_init
used by arm64. However, if you feel strongly about it, I am happy to
move back those two functions to arm64.
I don't have a strong view on this, only if there's a risk at some point
of the implementations diverging (e.g. quirks). We can revisit it if
that happens.
Sure. I seriously hope we don't have to deal with arch specific quirks
in future.
It may be worth swapping patches 1 and 2 so that you don't have an
arm64_* function in the core code after the first patch (more of a
nitpick). Either way, feel free to add my ack on both patches:
Sure. I will swap 1 & 2 and resend the series.
