    Subject[PATCH tip/core/rcu 0/14] Fixups for 3.6
    Hello!

    This patch series has general fixups and improvements:

    1. Get rid of the false positives from the code that recognizes
    a CPU stall that ends just as it is detected.
    2. Consolidate open-coded initializations of RCU callback lists.
    3. Protect unsynchronized accesses to ->qlen with ACCESS_ONCE()
    to document the unsynchronized access and to prevent compiler
    mischief.
    4. Add INIT_RCU_POINTER() for static initialization to allow
    do-while formulation of the existing RCU_INIT_POINTER().
    5. Convert clever use of RCU_INIT_POINTER() for gcc-style
    initialization to INIT_RCU_POINTER().
    6. Wrap RCU_INIT_POINTER() macro in obligatory do-while.
    7. Remove extraneous parentheses from rcu_assign_keypointer()
    to allow rcu_assign_pointer() to be wrapped in do-while.
    8. Wrap rcu_assign_pointer() macro in obligatory do-while.
    9. Consolidate the identical CONFIG_TREE_PREEMPT_RCU and
    CONFIG_TINY_PREEMPT_RCU versions of __rcu_read_lock() and
    __rcu_read_unlock().
    10. Remove the old inline-function version of __kfree_rcu() and
    __is_kfree_rcu_offset().
    11. Make __call_rcu() correctly handle calls from the idle loop.
    12. Make __call_rcu() correctly handle calls from a CPU that is
    in the process of going offline.
    13. Split __call_rcu() into the part that actually deals with
    enqueueing the callback and the part that kicks RCU's
    grace-period machinery.
    14. Make RCU_TINY's rcu_is_cpu_idle() function safe for "make
    randconfig".

    Thanx, Paul
