c0d83745cc [PATCH] i386: mark two more functions as __init
cyrix_identify() should be __init because transmeta_identify() is.
tsc_init() is only called from setup_arch() which is marked as __init.

These two section mismatches have been detected using running modpost on
a vmlinux image compiled with CONFIG_RELOCATABLE=y.

7f9f303aa3 [PATCH] generic-time: add macro to simplify/hide mask constants
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.

a275254975 [PATCH] time: rename clocksource functions
As suggested by Roman Zippel, change clocksource functions to use
clocksource_xyz rather then xyz_clocksource to avoid polluting the
namespace.

5d0cf410e9 [PATCH] Time: i386 Clocksource Drivers
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.

6f84fa2f3e [PATCH] Time: i386 Conversion - part 3: Enable Generic Timekeeping
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.

539eb11e6e [PATCH] Time: i386 Conversion - part 2: Rework TSC Support
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.
