Hi,

the patch "sched-sibling-map-to-cpumask.patch" inroduced following compile 
error on UP machines:

  CC [M]  arch/i386/kernel/cpu/cpufreq/p4-clockmod.o
arch/i386/kernel/cpu/cpufreq/p4-clockmod.c: In function `cpufreq_p4_setdc':
arch/i386/kernel/cpu/cpufreq/p4-clockmod.c:71: error: `cpu_sibling_map' 
undeclared (first use in this function)
arch/i386/kernel/cpu/cpufreq/p4-clockmod.c:71: error: (Each undeclared 
identifier is reported only once
arch/i386/kernel/cpu/cpufreq/p4-clockmod.c:71: error: for each function it 
appears in.)

The attached patch fixes it...
