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.

+	---help---
+	  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_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

+	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.

-	  name of a bus system, i.e. the way the CPU talks to the other stuff
-	  inside your box.  Other bus systems are PCI, EISA, MicroChannel
-	  (MCA) or VESA.  ISA is an older system, now being displaced by PCI;
-	  newer boards don't support it.  If you have ISA, say Y, otherwise N.
-
-config EISA
-	bool "EISA support"
-	depends on ISA
-	---help---
-	  The Extended Industry Standard Architecture (EISA) bus was
-	  developed as an open alternative to the IBM MicroChannel bus.
-
-	  The EISA bus provided some of the features of the IBM MicroChannel
-	  bus while maintaining backward compatibility with cards made for
-	  the older ISA bus.  The EISA bus saw limited use between 1988 and
-	  1995 when it was made obsolete by the PCI bus.
-
-	  Say Y here if you are building a kernel for an EISA-based machine.
-
-	  Otherwise, say N.

-	help
-	  MicroChannel Architecture is found in some IBM PS/2 machines and
-	  laptops.  It is a bus system similar to PCI or ISA. See
-	  <file:Documentation/mca.txt> (and especially the web page given
-	  there) before attempting to build an MCA bus kernel.

-	depends on !X86_VOYAGER
-	help
-	  This provides basic support for National Semiconductor's
-	  (now AMD's) Geode processors.  The driver probes for the
-	  PCI-IDs of several on-chip devices, so its a good dependency
-	  for other scx200_* drivers.
-

-config SCx200HR_TIMER

-	default y
-	help
-	  This driver provides a clocksource built upon the on-chip
-	  27MHz high-resolution timer.  Its also a workaround for
-	  NSC Geode SC-1100's buggy TSC, which loses time when the
-	  processor goes idle (as is done by the scheduler).  The
-	  other workaround is idle=poll boot option.

-	bool "Geode Multi-Function General Purpose Timer (MFGPT) events"
-	depends on MGEODE_LX && GENERIC_TIME && GENERIC_CLOCKEVENTS
-	default y
-	help
-	  This driver provides a clock event source based on the MFGPT
-	  timer(s) in the CS5535 and CS5536 companion chip for the geode.
-	  MFGPTs have a better resolution and max interval than the
-	  generic PIT, and are suitable for use as high-res timers.
