    Subject[PATCH 4.5 199/200] stm class: Select CONFIG_SRCU
    Date
    4.5-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.

    A System Trace Module (STM) is a device exporting data in System
    Trace Protocol (STP) format as defined by MIPI STP standards.
