## Description

In the Linux kernel, the following vulnerability has been resolved:  clocksource: Use migrate_disable() to avoid calling get_random_u32() in atomic context  The following bug report happened with a PREEMPT_RT kernel:    BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:48   in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 2012, name: kwatchdog   preempt_count: 1, expected: 0   RCU nest depth: 0, expected: 0   get_random_u32+0x4f/0x110   clocksource_verify_choose_cpus+0xab/0x1a0   clocksource_verify_percpu.part.0+0x6b/0x330   clocksource_watchdog_kthread+0x193/0x1a0  It is due to the fact that clocksource_verify_choose_cpus() is invoked with preemption disabled.  This function invokes get_random_u32() to obtain random numbers for choosing CPUs.  The batched_entropy_32 local lock and/or the base_crng.lock spinlock in driver/char/random.c will be acquired during the call. In PREEMPT_RT kernel, they are both sleeping locks and so cannot be acquired in atomic context.  Fix this problem by using migrate_disable() to allow smp_processor_id() to be reliably used without introducing atomic context. preempt_disable() is then called after clocksource_verify_choose_cpus() but before the clocksource measurement is being run to avoid introducing unexpected latency.
