fix cpumask.h in mainline for UPu

I'm trying to replace for_each_cpu() with for_each_cpu_mask() in arch/i386/kernel/cpu/cpufreq/p4-clockmod.c

Unfortunately, though, davej pointed me that for_each_cpu_mask() is not defined in -bk if CONFIG_SMP is not defined. Since this macro is the only one not defined if compiled for UP, and since -mm tree do have the correct behaviour already, is it possible to get this patch in mainline before this portion of -mm is merged?

Yup, I'll merge that up prior to 2.6.7, thanks.
