x86: start unification of arch/x86/Kconfig.*

This step introduces the file arch/x86/Kconfig
which contains all the menu's from "Power Management"
and below.

The main part of the new Kconfig file is shared
and the remaining i386/x86_64 specific symbols
are covered by dependencies.

A x86_64 allmodconfig build did not show any differences.

+          APM is a BIOS specification for saving power using several different
+          techniques. This is mostly useful for battery powered laptops with
+          APM compliant BIOSes. If you say Y here, the system time will be
+          reset after a RESUME operation, the /proc/apm device will provide
+          battery status information, and user-space programs will receive
+          notification of APM "events" (e.g. battery status change).
+
+          If you select "Y" here, you can disable actual use of the APM
+          BIOS by passing the "apm=off" option to the kernel at boot time.
+
+          Note that the APM support is almost completely disabled for
+          machines with more than one CPU.
+
+          In order to use APM, you will need supporting software. For location
+          and more information, read <file:Documentation/pm.txt> and the
+          Battery Powered Linux mini-HOWTO, available from
+          <http://www.tldp.org/docs.html#howto>.
+
+          This driver does not spin down disk drives (see the hdparm(8)
+          manpage ("man 8 hdparm") for that), and it doesn't turn off
+          VESA-compliant "green" monitors.
+
+          This driver does not support the TI 4000M TravelMate and the ACER
+          486/DX4/75 because they don't have compliant BIOSes. Many "green"
+          desktop machines also don't have compliant BIOSes, and this driver
+          may cause those machines to panic during the boot phase.
+
+          Generally, if you don't have a battery in your machine, there isn't
+          much point in using this driver and you should say N. If you get
+          random kernel OOPSes or reboots that don't seem to be related to
+          anything, try disabling/enabling this option (or disabling/enabling
+          APM in your BIOS).
+
+          Some other things you should try when experiencing seemingly random,
+          "weird" problems:
+
+          1) make sure that you have enough swap space and that it is
+          enabled.
+          2) pass the "no-hlt" option to the kernel
+          3) switch on floating point emulation in the kernel and pass
+          the "no387" option to the kernel
+          4) pass the "floppy=nodma" option to the kernel
+          5) pass the "mem=4M" option to the kernel (thereby disabling
+          all but the first 4 MB of RAM)
+          6) make sure that the CPU is not over clocked.
+          7) read the sig11 FAQ at <http://www.bitwizard.nl/sig11/>
+          8) disable the cache from your BIOS settings
+          9) install a fan for the video card or exchange video RAM
+          10) install a better fan for the CPU
+          11) exchange RAM chips
+          12) exchange the motherboard.
+
+          To compile this driver as a module, choose M here: the
+          module will be called apm.

+
+config APM_IGNORE_USER_SUSPEND
+        bool "Ignore USER SUSPEND"
+        help
+          This option will ignore USER SUSPEND requests. On machines with a
+          compliant APM BIOS, you want to say N. However, on the NEC Versa M
+          series notebooks, it is necessary to say Y because of a BIOS bug.
+
+config APM_DO_ENABLE
+        bool "Enable PM at boot time"
+        ---help---
+          Enable APM features at boot time. From page 36 of the APM BIOS
+          specification: "When disabled, the APM BIOS does not automatically
+          power manage devices, enter the Standby State, enter the Suspend
+          State, or take power saving steps in response to CPU Idle calls."
+          This driver will make CPU Idle calls when Linux is idle (unless this
+          feature is turned off -- see "Do CPU IDLE calls", below). This
+          should always save battery power, but more complicated APM features
+          will be dependent on your BIOS implementation. You may need to turn
+          this option off if your computer hangs at boot time when using APM
+          support, or if it beeps continuously instead of suspending. Turn
+          this off if you have a NEC UltraLite Versa 33/C or a Toshiba
+          T400CDT. This is off by default since most machines do fine without
+          this feature.
+
+config APM_CPU_IDLE
+        bool "Make CPU Idle calls when idle"
+        help
+          Enable calls to APM CPU Idle/CPU Busy inside the kernel's idle loop.
+          On some machines, this can activate improved power savings, such as
+          a slowed CPU clock rate, when the machine is idle. These idle calls
+          are made after the idle loop has run for some length of time (e.g.,
+          333 mS). On some machines, this will cause a hang at boot time or
+          whenever the CPU becomes idle. (On machines with more than one CPU,
+          this option does nothing.)
+
+config APM_DISPLAY_BLANK
+        bool "Enable console blanking using APM"
+        help
+          Enable console blanking using the APM. Some laptops can use this to
+          turn off the LCD backlight when the screen blanker of the Linux
+          virtual console blanks the screen. Note that this is only used by
+          the virtual console screen blanker, and won't turn off the backlight
+          when using the X Window system. This also doesn't have anything to
+          do with your VESA-compliant power-saving monitor. Further, this
+          option doesn't work for all laptops -- it might not turn off your
+          backlight at all, or it might print a lot of errors to the console,
+          especially if you are using gpm.
+
+config APM_ALLOW_INTS
+        bool "Allow interrupts during APM BIOS calls"
+        help
+          Normally we disable external interrupts while we are making calls to
+          the APM BIOS as a measure to lessen the effects of a badly behaving
+          BIOS implementation.  The BIOS should reenable interrupts if it
+          needs to.  Unfortunately, some BIOSes do not -- especially those in
+          many of the newer IBM Thinkpads.  If you experience hangs when you
+          suspend, try setting this to Y.  Otherwise, say N.
+
+config APM_REAL_MODE_POWER_OFF
+        bool "Use real mode APM BIOS call to power off"

+          a work-around for a number of buggy BIOSes. Switch this option on if
+          your computer crashes instead of powering off properly.
