Subject: [PATCH 2/3] sched/preempt: include asm/current.h

The generic preempt code needs to include <asm/current.h>. Otherwise
compilation fails if THREAD_INFO_IN_TASK is selected and the generic
preempt code is used:

./include/linux/thread_info.h:17:54: error: 'current' undeclared (first use in this function)
 #define current_thread_info() ((struct thread_info *)current)
