[PATCH -tip v3 3/9] perf probe: Fix bugs in line range finder
Fix find_line_range_by_line() to init line_list and remove misconseptional found marking which should be done when real lines are found (if there is no lines probe-able, find_line_range() should return 0).

[PATCH RFC] rcu: RCU CPU stall patches backported to 2.6.33-rc8
Hello! This set backports a couple of RCU CPU stall detection patches from the earlier series (http://lkml.org/lkml/2010/2/22/384) to 2.6.33-rc8 to help track down some NMI issues. These two patches fix an embarrassing deadlock that can affect TREE_PREEMPT_RCU and add additional per-task output when tasks stal... 22 Feb 2010 20:56

[PATCH tip/core/rcu 0/21] v6 add lockdep-based diagnostics to rcu_dereference()
Hello! This patch series adds lockdep-based checking to the rcu_dereference() primitive in order to flag misuses of RCU. The first four patches put the RCU infrastructure in place, the next eight use this infrastructure in the net, sched, vfs, radix-tree, idr, and security subsystems, and patch 13 documents how... 22 Feb 2010 20:55

[PATCH tip/core/rcu 02/21] rcu: add lockdep-enabled variants of rcu_dereference()
Make rcu_dereference() check for being in an RCU read-side critical section, and create rcu_dereference_bh(), rcu_dereference_sched(), and srcu_dereference() to check for the other flavors of RCU. Also create rcu_dereference_raw() to avoid checking, and make rcu_dereference_check() use rcu_dereference_raw(). Ac... 22 Feb 2010 20:55

[PATCH tip/core/rcu 19/21] rcu: fix deadlock in TREE_PREEMPT_RCU CPU stall detection
Under TREE_PREEMPT_RCU, print_other_cpu_stall() invokes rcu_print_task_stall() with the root rcu_node structure's ->lock held, and rcu_print_task_stall() acquires that same lock for self-deadlock. Fix this by removing the lock acquisition from rcu_print_task_stall(), and making all callers acquire the lock instead.... 22 Feb 2010 20:55
