[ Upstream commit f7b21a0e41171d22296b897dac6e4c41d2a3643c ]

Fix:

../arch/x86/include/asm/proto.h:14:30: warning: ‘struct task_struct’ declared \
inside parameter list will not be visible outside of this definition or declaration
long do_arch_prctl_64(struct task_struct *task, int option, unsigned long arg2);
^~~~~~~~~~~

.../arch/x86/include/asm/proto.h:40:34: warning: ‘struct task_struct’ declared \
inside parameter list will not be visible outside of this definition or declaration
long do_arch_prctl_common(struct task_struct *task, int option,
^~~~~~~~~~~

if linux/sched.h hasn't be included previously. This fixes a build error
when this header is used outside of the kernel tree.
