CONFIG_ACPI_DEBUG can be helpful for getting debug messages on OEM
systems to identify a BIOS bug. It's a relatively small size increase
to turn it on by default (50kb) and that saves asking people to enable
it when an issue comes up because it wasn't in defconfig.
Enable it by default.

Rafael,
Any thoughts on this? Especially in seeing Ingo trying to modernize
more of the defconfig [1]?

I'm not sure if this is a good idea TBH.
The risk is that people will start reporting issues that have been
there already, but now they become visible due to enabling ACPI_DEBUG
by default.
As several distros already enable it by default I would have expected
some "noise" like this to have settled down.
Do you have specific messages in mind you think could be turning noisy
from the extra debug statements?

The ACPI subsystem can produce debug output. Saying Y enables this
output and increases the kernel size by around 50K.
