Subject: [PATCH v2 05/15] sched/debug: Use unsigned long for cpu variable to prevent cast errors

This avoids compiler errors seen with clang:

In file included from kernel/sched/build_utility.c:72:
kernel/sched/debug.c:532:47: error: cast to 'void *' from smaller integer
	type 'unsigned int' [-Werror,-Wint-to-void-pointer-cast]
debugfs_create_file("runtime", 0644, d_cpu, (void *) cpu, &fair_server_runtime_fops);
