      "message": "rcu: Add a TINY_PREEMPT_RCU\n\nImplement a small-memory-footprint uniprocessor-only implementation of\npreemptible RCU.  This implementation uses but a single blocked-tasks\nlist rather than the combinatorial number used per leaf rcu_node by\nTREE_PREEMPT_RCU, which reduces memory consumption and greatly simplifies\nprocessing.  This version also takes advantage of uniprocessor execution\nto accelerate grace periods in the case where there are no readers.\n\nThe general design is otherwise broadly similar to that of TREE_PREEMPT_RCU.\n\nThis implementation is a step towards having RCU implementation driven\noff of the SMP and PREEMPT kernel configuration variables, which can\nhappen once this implementation has accumulated sufficient experience.\n\nRemoved ACCESS_ONCE() from __rcu_read_unlock() and added barrier() as\nsuggested by Steve Rostedt in order to avoid the compiler-reordering\nissue noted by Mathieu Desnoyers (http://lkml.org/lkml/2010/8/16/183).\n\nAs can be seen below, CONFIG_TINY_PREEMPT_RCU represents almost 5Kbyte\nsavings compared to CONFIG_TREE_PREEMPT_RCU.  Of course, for non-real-time\nworkloads, CONFIG_TINY_RCU is even better.\n\n\tCONFIG_TREE_PREEMPT_RCU\n\n\t   text\t   data\t    bss\t    dec\t   filename\n\t     13\t      0\t      0\t     13\t   kernel/rcupdate.o\n\t   6170\t    825\t     28\t   7023\t   kernel/rcutree.o\n\t\t\t\t   ----\n\t\t\t\t   7026    Total\n\n\tCONFIG_TINY_PREEMPT_RCU\n\n\t   text\t   data\t    bss\t    dec\t   filename\n\t     13\t      0\t      0\t     13\t   kernel/rcupdate.o\n\t   2081\t     81\t      8\t   2170\t   kernel/rcutiny.o\n\t\t\t\t   ----\n\t\t\t\t   2183    Total\n\n\tCONFIG_TINY_RCU (non-preemptible)\n\n\t   text\t   data\t    bss\t    dec\t   filename\n\t     13\t      0\t      0\t     13\t   kernel/rcupdate.o\n\t    719\t     25\t      0\t    744\t   kernel/rcutiny.o\n\t\t\t\t    ---\n\t\t\t\t    757    Total\n\nRequested-by: Loïc Minier \u003cloic.minier@canonical.com\u003e\nSigned-off-by: Paul E.
