Hi,
I am doing some clean up in x86 ftrace code. I check the performance by
switching between different tracers and by enabling and disabling them.
The operation has started to be much slower after rebasing on the
kernel tip tree. Bisecting has shown that the difference was caused by

This patch series adds more features to the perf timechart command:
* -n option that adds possibility to limit number of tasks on SVG
* -T option that adds possibility to show only tasks related info
* -T and -P options now work with `perf timechart record` command to keep
perf.data small
* -g
If we don't want either power or task events we may use -T or -P
with the `perf timechart record` command to filter out events while

Seems overkill. I guess the long option is enough, and in perf
short options already need to be considered a precious resource,
as they may
Currently we don't create default CPU map for task related
target, like:
$ perf record -p
This makes record command to disable inherited events.
which is not desired behaviour (we have special option
for that (-i) anyway).
Fixing this by creating default CPU map for task related
processes.

Add legacy pm_ops usage checks to device_pm_add() when a device gets added
to PM core's list of active devices. If legacy pm_ops usage is found at its
class, bus, driver level, print warning message to indicate the driver code
needs updating to use dev pm ops interfaces. This will help serve as a

Subject: fix race between stop_two_cpus and stop_cpus

It is possible for two CPUs to get their stopper functions queued
"backwards" from one another, resulting in the stopper threads
