It would be better to send these patches separately, because they
touch code maintained by different people and I guess no one will take
the whole series.

I'll take care of the ACPI one, but the rest needs to go in via their
proper trees.

Thanks for the note. From now onwards, I will send it separately

Applied.

But I would seriously suggest that when you have to cross subsystems
like this, just send the patches individually to the respective
maintainers rather than trying to make a "series" out of it.

Thanks.
