  "message": "context_tracking: Restore preempted context state after preempt_schedule_irq()\n\nFrom the context tracking POV, preempt_schedule_irq() behaves pretty much\nlike an exception: It can be called anytime and schedule another task.\n\nBut currently it doesn\u0027t restore the context tracking state of the preempted\ncode on preempt_schedule_irq() return.\n\nAs a result, if preempt_schedule_irq() is called in the tiny frame between\nuser_enter() and the actual return to userspace, we resume userspace with\nthe wrong context tracking state.\n\nFix this by using exception_enter/exit() which are a perfect fit for this\nkind of issue.\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Li Zhong \u003czhong@linux.vnet.ibm.com\u003e\nCc: Kevin Hilman \u003ckhilman@linaro.org\u003e\nCc: Mats Liljegren \u003cmats.liljegren@enea.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Ingo Molnar \u003cmingo@kernel.org\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Namhyung Kim \u003cnamhyung.kim@lge.com\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Paul E.
