Mike Frysinger 1bbfa6f256 sched: Mark sched_clock() as notrace 
The core ftrace code (trace_clock_local) calls sched_clock()
directly, so we don't want to recurisvely trigger the ftrace
code.  Rather than update every sched_clock() definition, tag
the prototype for everyone as notrace.

Frederic Weisbecker 3786310afe perf sched: Add max delay time snapshot 
When we have a maximum latency reported for a task, we need a
convenient way to find the matching location to the raw traces
or to perf sched map that shows where the task has been
eventually scheduled in. This gives a pointer to retrieve the
events that occured during this max latency.

Xiao Guangrong c0c9e72150 perf sched: Fix for getting task's execution time 
In current code, task's execute time is got by reading
'/proc/<pid>/sched' file, it's wrong if the task is created
by pthread_create(), because every thread task has same pid.

This way also has two demerits:

 1: 'perf sched replay' can't work if the kernel is not
    compiled with the 'CONFIG_SCHED_DEBUG' option

 2: perf tool should depend on proc file system

So, this patch uses PERF_COUNT_SW_TASK_CLOCK to get task's
execution time instead of reading /proc file.

Changelog v2 -> v3:
use PERF_COUNT_SW_TASK_CLOCK instead of rusage() as Ingo's
suggestion

Frederic Weisbecker 822a696111 tracing/kprobes: Fix field creation's bad error handling 
When we define the common event fields in kprobe, we invert the error
handling and return immediately in case of success. Then we omit
to define specific kprobes fields (ip and nargs), and specific
kretprobes fields (func, ret_ip, nargs). And we only define them
when we fail to create common fields.

The most visible consequence is that we can't create filter for
k(ret)probes specific fields.

This patch re-invert the success/error handling to fix it.

Frederic Weisbecker 44234adcdc hw-breakpoints: Modify breakpoints without unregistering them 
Currently, when ptrace needs to modify a breakpoint, like disabling
it, changing its address, type or len, it calls
modify_user_hw_breakpoint(). This latter will perform the heavy and
racy task of unregistering the old breakpoint and registering a new
one.

This is racy as someone else might steal the reserved breakpoint
slot under us, which is undesired as the breakpoint is only
supposed to be modified, sometimes in the middle of a debugging
workflow. We don't want our slot to be stolen in the middle.

So instead of unregistering/registering the breakpoint, just
disable it while we modify its breakpoint fields and re-enable it
after if necessary.

Masami Hiramatsu d1bde3f755 perf probe: Fix add-probe command syntax without --add option 
Fix add-probe command syntax without --add option.
perf-probe supports add-probe command without --add
option. But it treats each argument as an event definition.
e.g.

perf probe func arg1 arg2

 is interpreted as

perf probe --add func --add arg1 --add arg2

But it may be useless in many cases.

This patch fixes this syntax to fold those arguments into
one event definition if there is no --add option. With this
change, above command is interpreted as below;

perf probe --add "func arg1 arg2"
