      "message": "perf: Fetch hot regs from the template caller\n\nTrace events can be defined from a template using\nDECLARE_EVENT_CLASS/DEFINE_EVENT or directly with TRACE_EVENT.\n\nIn both cases we have a template tracepoint handler, used to\nrecord the trace, to which we pass our ftrace event instance.\n\nIn the function level, if the class is named \"foo\" and the event\nis named \"blah\", we have the following chain of calls:\n\nperf_trace_blah() -\u003e perf_trace_templ_foo()\n\nIn the case we have several events sharing the class \"blah\",\nwe\u0027ll have multiple users of perf_trace_templ_foo(), and it\nwon\u0027t be inlined by the compiler. This is usually what happens\nwith the DECLARE_EVENT_CLASS/DEFINE_EVENT based definition.\n\nBut if perf_trace_blah() is the only caller of perf_trace_templ_foo()\nthere are fair chances that it will be inlined.\n\nThe problem is that we fetch the regs from perf_trace_templ_foo()\nafter we rewinded the frame pointer to the second caller, we want\nto reach the caller of perf_trace_blah() to get the right source\nof the event. And we do this by always assuming that\nperf_trace_templ_foo() is not inlined. But as shown above this\nis not always true. And if it is inlined we miss the first caller,\nlosing the most important level of precision.\n\nWe get:\n\t    61.31%       ls  [kernel.kallsyms]  [k] do_softirq\n                         |\n                         --- do_softirq\n                             irq_exit\n                             do_IRQ\n                             common_interrupt\n                            |\n                            |--25.00%-- tty_buffer_request_room\n\nInstead of:\n\t    61.31%       ls  [kernel.kallsyms]  [k] __do_softirq\n                         |\n                         --- __do_softirq\n                             do_softirq\n                             irq_exit\n                             do_IRQ\n                             common_interrupt\n                            |\n                            |--25.00%-- tty_buffer_request_room\n\nTo fix this, we fetch the regs from perf_trace_blah() rather than\nperf_trace_templ_foo() so that we don\u0027t have to deal with inlining\nsurprises.\n\nThat also bring us the advantage of having the true source of the\nevent even if we don\u0027t have frame pointers.\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

      "message": "tracing: Fix ftrace_event_call alignment for use with gcc 4.5\n\nGCC 4.5 introduces behavior that forces the alignment of structures to\n use the largest possible value. The default value is 32 bytes, so if\n some structures are defined with a 4-byte alignment and others aren\u0027t\n declared with an alignment constraint at all - it will align at 32-bytes.\n\n For things like the ftrace events, this results in a non-standard array.\n When initializing the ftrace subsystem, we traverse the _ftrace_events\n section and call the initialization callback for each event. When the\n structures are misaligned, we could be treating another part of the\n structure (or the zeroed out space between them) as a function pointer.\n\n This patch forces the alignment for all the ftrace_event_call structures\n to 4 bytes.\n\n Without this patch, the kernel fails to boot very early when built with\n gcc 4.5.\n\n It\u0027s trivial to check the alignment of the members of the array, so it\n might be worthwhile to add something to the build system to do that\n automatically. Unfortunately, that only covers this case. I\u0027ve asked one\n of the gcc developers about adding a warning when this condition is seen.\n\nCc: stable@kernel.org\nSigned-off-by: Jeff Mahoney \u003cjeffm@suse.com\u003e\nLKML-Reference: \u003c4B85770B.6010901@suse.com\u003e\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n"

The code to enable, disable and\nrecord is created for every trace point even if most of the code is\nidentical.\n\nThis patch adds TRACE_EVENT_TEMPLATE that lets the developer create\na template TRACE_EVENT and create trace points with DEFINE_EVENT, which\nis based off of a given template. Each trace point used by this\nwill share most of the code, and bring down the size of the kernel\nwhen there are several duplicate events.\n\nUsage is:\n\nTRACE_EVENT_TEMPLATE(name, proto, args, tstruct, assign, print);\n\nWhich would be the same as defining a normal TRACE_EVENT.\n\nTo create the trace events that the trace points will use:\n\nDEFINE_EVENT(template, name, proto, args) is done. The template\nis the name of the TRACE_EVENT_TEMPLATE to use. The name is the\nname of the trace point. The parameters proto and args must be the same\nas the proto and args of the template. If they are not the same,\nthen a compile error will result. I tried hard removing this duplication\nbut the C preprocessor is not powerful enough (or my CPP magic\nexperience points is not at a high enough level) to not need them.\n\nA lot of trace events are coming in with new XFS development.
