Subject: sched/s390: Fix compile error in sched/core.c
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=db7e527da41560f597ccdc4417cefa6b7657c0c0;p=openwrt%2Fstaging%2Fblogic.git

sched/s390: Fix compile error in sched/core.c

Commit 029632fbb7b7c9d85063cc9eb470de6c54873df3 ("sched: Make
separate sched*.c translation units") removed the include of
asm/mutex.h from sched.c.

This breaks the combination of:

 CONFIG_MUTEX_SPIN_ON_OWNER=yes
 CONFIG_HAVE_ARCH_MUTEX_CPU_RELAX=yes

like s390 without mutex debugging:

  CC      kernel/sched/core.o
  kernel/sched/core.c: In function ‘mutex_spin_on_owner’:
  kernel/sched/core.c:3287: error: implicit declaration of function ‘arch_mutex_cpu_relax’

Lets re-add the include to kernel/sched/core.c
