4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@arndb.de>
commit 042d4460b5b4379a12f375045ff9065cf6758735 upstream.
The newly added STM code uses SRCU, but does not ensure that this code is part of the kernel:
drivers/built-in.o: In function `stm_source_link_show': include/linux/srcu.h:221: undefined reference to `__srcu_read_lock' include/linux/srcu.h:238: undefined reference to `__srcu_read_unlock' drivers/built-in.o: In function `stm_source_link_drop': include/linux/srcu.h:221: undefined reference to `__srcu_read_lock' include/linux/srcu.h:238: undefined reference to `__srcu_read_unlock'
This adds a Kconfig 'select' statement like all the other SRCU using drivers have.
