We don't need THREAD_SIZE in asm-offsets.c as we can just calculate
the value of init_thread_union + THREAD_SIZE using cpp, just like

The cond_resched() can be used to yield the CPU resource if
CONFIG_PREEMPT is not defined. Otherwise, cond_resched() is a dummy
function. In order to avoid kernel thread occupying entire CPU,
when CONFIG_PREEMPT=y, the kernel thread needs to follow the
rescheduling mechanism like a user thread.
