Hi Rusty,

Today's linux-next build (x86_64 allmodconfig) produced this warning:

arch/x86/kernel/cpu/cpufreq/powernow-k8.c:1287: warning: passing argument 1 of 'check_supported_cpu' makes pointer from integer without a cast
arch/x86/kernel/cpu/cpufreq/powernow-k8.c:514: note: expected 'void *' but argument is of type 'unsigned int'

Introduced by commit b3594a9ce5fb32533084ec75f1954c93f461591d ("cpumask:
avoid playing with cpus_allowed in powernow-k8.c").
