Hello again, Lai,

I hit the following build error during testing:

kernel/built-in.o: In function `.synchronize_rcu_expedited':
(.text+0x787d8): undefined reference to `.synchronize_sched_expedited'
kernel/built-in.o:(.toc1+0x1fe0): undefined reference to `synchronize_sched_expedited'

This build uses defconfig with the following applied:

CONFIG_RCU_TRACE=y
CONFIG_RCU_FAST_NO_HZ=y
CONFIG_NO_HZ=y
CONFIG_RCU_CPU_STALL_DETECTOR=y
CONFIG_SMP=y
CONFIG_RCU_FANOUT=8
CONFIG_NR_CPUS=8
CONFIG_RCU_FANOUT_EXACT=n
CONFIG_HOTPLUG_CPU=y
CONFIG_PREEMPT_NONE=y
CONFIG_PREEMPT_VOLUNTARY=n
CONFIG_PREEMPT=n
CONFIG_TREE_RCU=y
CONFIG_TREE_PREEMPT_RCU=n
CONFIG_RCU_TORTURE_TEST=m
CONFIG_MODULE_UNLOAD=y
CONFIG_SYSFS_DEPRECATED_V2=y
CONFIG_IKCONFIG=y
CONFIG_IKCONFIG_PROC=y

Thoughts?

Thanx, Paul
