mainlining shenanigans

When --timeout is used and a workload is specified to be started by
'perf stat', i.e.
$ perf stat --timeout 1000 sleep 1h
The --timeout wasn't being honoured, i.e. the workload, 'sleep 1h' in
the above example, should be terminated after 1000ms, but it wasn't,
'perf stat' was waiting for it to finish.
Fix it by sending a SIGTERM when the timeout expires.
Now it works:
# perf stat -e cycles --timeout 1234 sleep 1h
sleep: Terminated
Performance counter stats for 'sleep 1h':
1,066,692 cycles
1.234314838 seconds time elapsed
0.000750000 seconds user
0.000000000 seconds sys

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
