Naga Chumbalkar c780713f78 drivers/cpufreq/pcc-cpufreq.c: avoid NULL pointer dereference ... commit e71f5cc402 upstream. per_cpu(processors, n) can be NULL, resulting in: Loading CPUFreq modules[ 437.661360] BUG: unable to handle kernel NULL pointer dereference at (null) IP: [<ffffffffa0434314>] pcc_cpufreq_cpu_init+0x74/0x220 [pcc_cpufreq] It's better to avoid the oops by failing the driver, and allowing the system to boot.
