-	help
-	  This adds the CPUFreq driver for Intel Pentium 4 / XEON
-	  processors.  When enabled it will lower CPU temperature by skipping
-	  clocks.
-
-	  This driver should be only used in exceptional
-	  circumstances when very low power is needed because it causes severe
-	  slowdowns and noticeable latencies.  Normally Speedstep should be used
-	  instead.

-	tristate "VIA C7 Enhanced PowerSaver (DANGEROUS)"
-	select CPU_FREQ_TABLE
-	depends on X86_32 && EXPERIMENTAL
-	help
-	  This adds the CPUFreq driver for VIA C7 processors.  However, this driver
-	  does not have any safeguards to prevent operating the CPU out of spec
-	  and is thus considered dangerous.  Please use the regular ACPI cpufreq
-	  driver, enabled by CONFIG_X86_ACPI_CPUFREQ.
-
-	  If in doubt, say N.

-	bool "Relaxed speedstep capability checks"
-	depends on X86_32 && (X86_SPEEDSTEP_SMI || X86_SPEEDSTEP_ICH)
-	help
-	  Don't perform all checks for a speedstep capable system which would
-	  normally be done. Some ancient or strange systems, though speedstep
-	  capable, don't always indicate that they are speedstep capable. This
-	  option lets the probing code bypass some of those checks if the
-	  parameter "relaxed_check=1" is passed to the module.

- *
- * Theoretical note:
- *
- *	(see Geode(tm) CS5530 manual (rev.4.1) page.56)
- *
- *	CPU frequency control on NatSemi Geode GX1/GXLV processor and CS55x0
- *	are based on Suspend Modulation.
- *
- *	Suspend Modulation works by asserting and de-asserting the SUSP# pin
- *	to CPU(GX1/GXLV) for configurable durations. When asserting SUSP#
- *	the CPU enters an idle state. GX1 stops its core clock when SUSP# is
- *	asserted then power consumption is reduced.
- *
- *	Suspend Modulation's OFF/ON duration are configurable
- *	with 'Suspend Modulation OFF Count Register'
- *	and 'Suspend Modulation ON Count Register'.
- *	These registers are 8bit counters that represent the number of
- *	32us intervals which the SUSP# pin is asserted(ON)/de-asserted(OFF)
- *	to the processor.
- *
- *	These counters define a ratio which is the effective frequency
- *	of operation of the system.
- *
- *			       OFF Count
- *	F_eff = Fgx * ----------------------
- *	                OFF Count + ON Count
- *
- *	0 <= On Count, Off Count <= 255
- *
- *	From these limits, we can get register values
- *
- *	off_duration + on_duration <= MAX_DURATION
- *	on_duration = off_duration * (stock_freq - freq) / freq
- *
- *      off_duration  =  (freq * DURATION) / stock_freq
- *      on_duration = DURATION - off_duration
- *
- *
- *---------------------------------------------------------------------------
- *
- * ChangeLog:
- *	Dec. 12, 2003	Hiroshi Miura <miura@da-cha.org>
- *		- fix on/off register mistake
- *		- fix cpu_khz calc when it stops cpu modulation.
- *
- *	Dec. 11, 2002	Hiroshi Miura <miura@da-cha.org>
- *		- rewrite for Cyrix MediaGX Cx5510/5520 and
- *		  NatSemi Geode Cs5530(A).
- *
- *	Jul. ??, 2002  Zwane Mwaikambo <zwane@commfireservices.com>
- *		- cs5530_mod patch for 2.4.19-rc1.
- *
- *---------------------------------------------------------------------------
- *
- * Todo
- *	Test on machines with 5510, 5530, 5530A

- *  Licensed under the terms of the GNU GPL License version 2.
- *  Based upon datasheets & sample CPUs kindly provided by VIA.
- *
- *  VIA have currently 3 different versions of Longhaul.
- *  Version 1 (Longhaul) uses the BCR2 MSR at 0x1147.
- *   It is present only in Samuel 1 (C5A), Samuel 2 (C5B) stepping 0.
- *  Version 2 of longhaul is backward compatible with v1, but adds
- *   LONGHAUL MSR for purpose of both frequency and voltage scaling.
- *   Present in Samuel 2 (steppings 1-7 only) (C5B), and Ezra (C5C).
- *  Version 3 of longhaul got renamed to Powersaver and redesigned
- *   to use only the POWERSAVER MSR at 0x110a.
- *   It is present in Ezra-T (C5M), Nehemiah (C5X) and above.
- *   It's pretty much the same feature wise to longhaul v2, though
- *   there is provision for scaling FSB too, but this doesn't work
- *   too well in practice so we don't even try to use this.
- *
- *  BIG FAT DISCLAIMER: Work in progress code. Possibly *dangerous*
