Subject[PATCH 40/46] kernel: Include appropriate header file in kernel/sched/core.c
Include appropriate header file include/linux/sched.h in
kernel/sched/core.c because it containes prototype declaration of
function defined in kernel/sched/core.c. Also, fix the typo error in
prototype declaration of function 'arch_sd_sibling_asym_packing’ in

This eliminates the following warning in sched/core.c:
kernel/sched/core.c:5814:12: warning: no previous prototype for ‘arch_sd_sibling_asym_packing’ [-Wmissing-prototypes]
