Centos is compiling it as module, it will fail;
Other user wants to compile it as module, they will fail, 
Syzbot random configuration building will fail

Unless prohibit to build it as module as below:

config HALTPOLL_CPUIDLE
-        tristate "Halt poll cpuidle driver"
+        bool "Halt poll cpuidle driver"
        depends on X86 && KVM_GUEST
        default y
        help


thanks
