* 'tracing-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: tracing: user local buffer variable for trace branch tracer tracing: fix warning on kernel/trace/trace_branch.c andtrace_hw_branches.c ftrace: check for failure for all conversions tracing: correct module boundaries for ftrace_release tracing: fix transposed numbers of lock_depth and preempt_count trace: Fix missing assignment in trace_ctxwake_* tracing: Use free_percpu instead of kfree tracing: Check total refcount before releasing bufs in profile_enable failure
