    Fix:
    
    arch/arm/mach-sa1100/generic.c:117: error: redefinition of 'cpufreq_get'
    include/linux/cpufreq.h:299: error: previous definition of 'cpufreq_get' was here
    
    cpufreq_get() is used on these platforms to tell drivers what the CPU
    frequency is, and therefore the bus frequency - which is critical for
    setting the PCMCIA and LCD timings.  Adding ifdefs to these drivers to
    select cpufreq_get() or some other interface adds confusion.  Making
    these drivers use some other interface for the normal paths and cpufreq
    stuff for the cpufreq notifier is insane as well.
    
    (Why x86 can't provide a version of cpufreq_get() which returns the
    CPU frequency when CPUFREQ is disabled is beyond me, rather than
    requiring a dummy zero-returning cpufreq_get().  Especially as they
    do:
    
    			unsigned long khz = cpufreq_get(cpu);
    			if (!khz)
    				khz = tsc_khz;
    
    In other words, if CPUFREQ is disabled, get it from tsc_khz - why
    not provide a dummy cpufreq_get() which returns tsc_khz?)
