Hi Kernel people.

Just installed the spiffy new 3.19 kernel from Kernel:stable, and when going
through journald logs to see if there was something new and exciting I came
over these warnings that I've seen for ages, but never cared for since it seem
to do no harm.

linux-ial4:~ # uname -r
3.19.0-1.g8a7d5f9-desktop

linux-ial4:~ # journalctl -b | grep CONFIG_ACPI_PROCFS_POWER
feb. 13 00:27:50 linux-ial4 kernel: ACPI: Deprecated procfs I/F for battery is
loaded, please retry with CONFIG_ACPI_PROCFS_POWER cleared
feb. 13 00:27:50 linux-ial4 kernel: ACPI: Deprecated procfs I/F for battery is
loaded, please retry with CONFIG_ACPI_PROCFS_POWER cleared
feb. 13 00:27:50 linux-ial4 kernel: ACPI: Deprecated procfs I/F for AC is
loaded, please retry with CONFIG_ACPI_PROCFS_POWER cleared
linux-ial4:~ #

But today I took the time to google it, and found this bug from Arch

https://bugs.archlinux.org/task/25845

Snip from bug 

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.

Short story this was disabled on Arch back in 2011


Could we do this for openSUSE too?
