    cpuidle: build fix for non-x86
    The last posted version of this patch gave compile error
    on IA64. So, here goes yet another rewrite of the patch.
    Convert cpu_idle_wait() to cpuidle_kick_cpus() which is
    SMP-only, and gives error on non supported CPU.
    Changes from last patch sent by Kevin:
    Moved the definition of kick_cpus back to cpuidle.c from cpuidle.h:
    * Having it in .h gives #error on archs which includes the header file 
      actually having CPU_IDLE configured. To make it work in .h, we need one 
      #ifdef around that code which makes it messy.
    * Also, the function is only called from one file. So, it can be in declared
      statically in .c rather than making it available to everyone who includes
      the .h file.
