This series contains some minor changes to SRCU: 1. Expand SRCU ->completed to 64 bits. This is to be consistent with rcutorture, which now pays attention to this field for more precise error checking. 2. Combine DEFINE_SRCU() and DEFINE_STATIC_SRCU(). 3. Make SRCU optional via a new CONFIG_SRCU Kconfig parameter, courtesy of Pranith Kumar. This saves about 2KB.
