Fix for followings:

WARNING: Use #include <linux/percpu.h> instead of <asm/percpu.h>
+#include <asm/percpu.h>

ERROR: Macros with multiple statements should be enclosed in a do - while

WARNING: usage of NR_CPUS is often wrong - consider using cpu_possible(),
num_possible_cpus(), for_each_possible_cpu(), etc
+       if (cpu >= NR_CPUS)
