Details

I already discussed this with Thomas, so this might be redundant. Just filing it so it is not forgotten.

I get the following warning in dmesg:

ACPI: Deprecated procfs I/F for battery is loaded, please retry with CONFIG_ACPI_PROCFS_POWER cleared

This was scheduled for removal in 2.6.39, but is still there. I suggest trying to disable it for 3.1, if for nothing else than to discover what problems this might cause so the appropriate bug reports can be filed.

From Documentation/feature-removal-schedule.txt:

What: CONFIG_ACPI_PROCFS_POWER
When: 2.6.39
Why: sysfs I/F for ACPI power devices, including AC and Battery, has been working in upstream kernel since 2.6.24, Sep 2007. In 2.6.37, we make the sysfs I/F always built in and this option disabled by default. Remove this option and the ACPI power procfs interface in 2.6.39.

We kept this option enabled because it was needed by KDE 3.5, and then we forgot it. Should be disabled nowadays.

Fixed on svn.

Shouldn't we disable CONFIG_ACPI_PROCFS entirely? All ACPI functionality should be in sysfs nowadays.

Disabled in 3.1
