Subject: [PATCH 4/5] ACPI: Remove CONFIG_ACPI_PROCFS_POWER and cm_sbsc.c
From: Lan Tianyu <tianyu.lan@...el.com>
There is no user of cm_sbs.c and CONFIG_ACPI_PROCFS_POWER. So remove
them. Prepare for removing /proc/acpi
Signed-off-by: Lan Tianyu <tianyu.lan@...el.com>

- help
- For backwards compatibility, this option allows
- deprecated power /proc/acpi/ directories to exist, even when
- they have been replaced by functions in /sys.
- The deprecated directories (and their replacements) include:
- /proc/acpi/battery/* (/sys/class/power_supply/*)
- /proc/acpi/ac_adapter/* (sys/class/power_supply/*)
- This option has no effect on /proc/acpi/ directories
- and functions, which do not yet exist in /sys
- This option, together with the proc directories, will be
- deleted in 2.6.39.
