I have to say: I'm not happy about this behaviour, we should only remove what 
we added and nothing more.

I have may overseen something, but where are the mails (with the patches) to 
all these ACPI/PMU/APM commits in the last hour? They are really confusing 
and I miss the discussion about them (at least the commit logs are also not 
that descriptive in some cases).

I hope they introduce no new ACPI related bugs, the code is really sensitive 
as you know.
