Yang Shi cf78070d8c ARM: 8839/1: kprobe: make patch_lock a raw_spinlock_t ... [ Upstream commit 143c2a89e0e5fda6c6fd08d7bc1126438c19ae90 ] When running kprobe on -rt kernel, the below bug is caught: |BUG: sleeping function called from invalid context at kernel/locking/rtmutex.c:931 |in_atomic(): 1, irqs_disabled(): 128, pid: 14, name: migration/0 |Preemption disabled at:[<802f2b98>] cpu_stopper_thread+0xc0/0x140 |CPU: 0 PID: 14 Comm: migration/0 Tainted: G O 4.8.3-rt2 #1 |Hardware name: Freescale LS1021A |[<8025a43c>] (___might_sleep) |[<80b5b324>] (rt_spin_lock) |[<80b5c31c>] (__patch_text_real) |[<80b5c3ac>] (patch_text_stop_machine) |[<802f2920>] (multi_cpu_stop) Since patch_text_stop_machine() is called in stop_machine() which disables IRQ, sleepable lock should be not used in this atomic context, so replace patch_lock to raw lock.
