2006-06-26[PATCH] generic-time: add macro to simplify/hide mask constantsJim Cromie
Add a CLOCKSOURCE_MASK macro to simplify initializing the mask for a struct clocksource, and use it to replace literal mask constants in the various clocksource drivers.

2006-06-26[PATCH] time: rename clocksource functionsjohn stultz
As suggested by Roman Zippel, change clocksource functions to use clocksource_xyz rather then xyz_clocksource to avoid polluting the namespace.

2006-06-26[PATCH] Time: i386 Clocksource Driversjohn stultz
Implement the time sources for i386 (acpi_pm, cyclone, hpet, pit, and tsc). With this patch, the conversion of the i386 arch to the generic timekeeping code should be complete. The patch should be fairly straight forward, only adding the new clocksources.

2006-06-26[PATCH] Time: i386 Conversion - part 3: Enable Generic Timekeepingjohn stultz
This converts the i386 arch to use the generic timeofday subsystem. It enabled the GENERIC_TIME option, disables the timer_opts code and other arch specific timekeeping code and reworks the delay code. While this patch enables the generic timekeeping, please note that this patch does not provide any i386 clocksource. Thus only the jiffies clocksource will be available. To get full replacements for the code being disabled here, the timeofday-clocks-i386 patch will needed.

2006-06-26[PATCH] Time: i386 Conversion - part 2: Rework TSC Supportjohn stultz
As part of the i386 conversion to the generic timekeeping infrastructure, this introduces a new tsc.c file. The code in this file replaces the TSC initialization, management and access code currently in timer_tsc.c (which will be removed) that we want to preserve. The code also introduces the following functionality: o tsc_khz: like cpu_khz but stores the TSC frequency on systems that do not change TSC frequency w/ CPU frequency o check/mark_tsc_unstable: accessor/modifier flag for TSC timekeeping usability o minor cleanups to calibration math. This patch also includes a one line __cpuinitdata fix from Zwane Mwaikambo.
