Remove CONFIG_ACPI_SYSTEM. It was always set the same as CONFIG_ACPI, and it had no menu label, so there was no way to set it to anything other than "y". Some things under CONFIG_ACPI_SYSTEM (acpi_irq_handled, acpi_os_gpe_count(), event_is_open, register_acpi_notifier(), etc.) are used unconditionally by the CA, the OSPM, and drivers, so we depend on them always being present.

Advanced Configuration and Power Interface (ACPI) support for
|
|
Linux requires an ACPI compliant platform (hardware/firmware),
|
|
and assumes the presence of OS-directed configuration and power
|
|
management (OSPM) software. This option will enlarge your
|
|
kernel by about 70K.
|
|
|
|
Linux ACPI provides a robust functional replacement for several
|
|
legacy configuration and power management interfaces, including
|
|
the Plug-and-Play BIOS specification (PnP BIOS), the
|
|
MultiProcessor Specification (MPS), and the Advanced Power
|
|
Management (APM) specification. If both ACPI and APM support
|
|
are configured, whichever is loaded first shall be used.
|
|
|
|
The ACPI SourceForge project contains the latest source code,
|
|
documentation, tools, mailing list subscription, and other
|
|
information. This project is available at:
|
|
<http://sourceforge.net/projects/acpi>
|
|
|
|
Linux support for ACPI is based on Intel Corporation's ACPI
|
|
Component Architecture (ACPI CA). For more information see:
|

ACPI is an open industry specification co-developed by Compaq,
|

Intel, Microsoft, Phoenix, and Toshiba. The specification is
