[patch 00/46] High resolution timer / dynamic tick update

This is a full replacement queue for the high resolution timer / dynamic 
ticks implemementation in -mm.

This version includes the following improvements:

 - Seperate clockevents management of devices and users

 - Provide a generic tick managament infrastructure, which makes use
   of the clock events management layer. This provides:

   - periodic tick management
   - broadcast management (e.g. to solve the APIC stops in C3 power
     state problem)
   - dynamic tick core functionality
   - high resolution timer core infrastructure

   This allows to provide dynamic ticks with low and high resolution
   timers by sharing the infrastructure. [read: CONFIG_NO_HZ=y is now
   available without CONFIG_HIGH_RES_TIMERS as well.]

   ( The dynamic tick implementation also contains a fix for the
     generic next_timer_interrupt() function, which did not do the
     cascade lookups correctly. )

 - Provide a generic way to verify clocksources. TSC needs
   verification due to broken hardware and BIOS implementations. The
   previous attempt to allow TSC usage for high resolution and/or
   dynamic ticks only in combination with the PM-Timer made hardwired
   assumptions, which are ugly to maintain. The new verification code
   solves this by chosing the best available clocksource for
   verification and handles the usability check for highres / dynamic
   ticks. This makes TSC code agnostic of other hardware available in
   the system.

 - Removed the dynamic tick specific parts from the high resolution
   timer code.

 - Dynamic ticks and high resolution timers can be disabled separately
   at compile time or at run time from the kernel command line.

      Thomas, Ingo

P.S:
Sorry for the resend. Did not notice my list typo. :(
