I've applied these, with some changes:

0001: Rather than changing the setting of CONFIG_ACPI_NFIT for arm64, I
removed it entirely as it would be redundant with the top-level config.

0002: I dropped several of the config symbols which are automatic.  Any
config symbol that doesn't have a description can only be enabled via
other symbols that select it.  These shouldn't be mentioned in
debian/config files.

I also removed CONFIG_ACPI_CONFIGFS as I have a concern that this
feature allows subverting Secure Boot.  If this feature is important to
you, I can investigate further and maybe add a patch to conditionally
disable it at run-time instead.

Ben.

Any sufficiently advanced bug is indistinguishable from a feature.

The changes you've committed look fine.  I have no need for
CONFIG_ACPI_CONFIGFS.  If it seems a risk, then I think
it OK to have it disabled until a real need comes up.
