This code in question was added via following commit:

S390] lockless get_user_pages_fast()
I guess that there is an #include <linux/rcupdate.h> missing in pgtable.c. I'll
add it to the patch.
I don't see definition for INIT_RCU_HEAD in rcupdate.h so adding rcupdate.h might
not help.
Infact i can't find usage/implementation of INIT_RCU_HEAD anywhere else in the code.
Is this macro deprecated ?
Thanks
