[ Upstream commit 183f47fcaa54a5ffe671d990186d330ac8c63b10 ]
The recent addition of in_serving_softirq() to kconv.h results in compile failure on PREEMPT_RT because it requires task_struct::softirq_disable_cnt. This is not available if kconv.h is included from sched.h.
It is not needed to include kconv.h from sched.h. All but the net/ user already include the kconv header file.
Move the include of the kconv.h header from sched.h it its users. Additionally include sched.h from kconv.h to ensure that everything task_struct related is available.
