The set-timer-lat test fails when testing CLOCK_BOOTTIME_ALARM
or CLOCK_REALTIME_ALARM when the user isn't running as root or
with CAP_WAKE_ALARM.
So this patch improves the error checking so we report the

For the default run_timers target, the timers tests takes the
majority of kselftests runtime.
So this patch reduces the default runtime for inconsistentcy-check
and set-timer-lat, which reduced the runtime almost in half.

rtctest.c checks to see if PIE is functioning by testing if 20 interrupts occur
at rates from 2HZ to 64HZ. While this check is good, it does not check to
see if the correct amount of time has actually passed. This misses
situations where the RTC may be operating at a higher or lower frequency
than expected.
This patch introduces a simple check to verify if the time passed is
less than 10% of what was programmed into the RTC.

This adds support for installing them, when on a powerpc machine, or if

This is a little more complicated because of the sub directory structure

This adds make install support to selftests. The basic usage is:
$ cd tools/testing/selftests
$ make install
That installs into tools/testing/selftests/install, which can then be
copied where ever necessary.
The install destination is also configurable using eg:
$ INSTALL_PATH=/mnt/selftests make install
The implementation uses two targets in the child makefiles. The first
"install" is expected to install all files into $(INSTALL_PATH).
The second, "emit_tests", is expected to emit the test instructions (ie.
bash script) on stdout. Separating this from install means the child
makefiles need no knowledge of the location of the test script.

This adds a Make include file which most selftests can then include to
get the run_tests logic.
On its own this has the advantage of some reduction in repetition, and
also means the pass/fail message is defined in fewer places.
However the key advantage is it will allow us to implement install very
simply in a subsequent patch.
The default implementation just executes each program in $(TEST_PROGS).
We use a variable to hold the default implementation of $(RUN_TESTS)
because that gives us a clean way to override it if necessary, ie. using
override. The mount, memory-hotplug and mqueue tests use that to provide
a different implementation.
Tests are not run via /bin/bash, so if they are scripts they must be
executable, we add a+x to several.

Since both success and failure may shortcut and exit ktest, it is better
to print the status times there too. Once times are printed, the values
for the times are reset, so they will not print more than once.

The function start_monitor_and_boot is a misnomer. It use to, but
now it starts the monitor and installs. It does not boot. Rename it
before I get confused by it again.

Seeing the times for how long a build, install, reboot and the
test takes is helpful for analyzing the test process. Seeing
how different changes affect the timings.
Show the build, install, boot and test times when at the end of
the test, or between each interval for tests that do those
mulitple times (like bisect and patchcheck).

When ktest runs the console program as a child process, the parent and
child share the same tty for stdin and stderr. This is problematic when
using a libvirt target. The "virsh console" program makes a lot of
changes to the tty settings, making ktest's output hard to read
(carriage returns don't work). After ktest exits, the terminal is
unusable (CRs broken, stdin isn't echoed).
I think the best way to fix this issue would be to create a
pseudoterminal (pty pair) so the child process would have a dedicated
tty, and then use pipes to connect the two ttys. I'm not sure if that's
overkill, but it's far beyond my current Perl abilities.
This patch is a much easier way to (partially) fix this issue. It saves
the tty settings before opening the console and restores them after
closing it. There are still a few places where ktest prints mangled
output while the console is open, but the output is much more legible
overall, and the terminal works just fine after ktest exits.

I find that I usually like to see how long a make or other command takes,
and adding a start and end time and reporting how long each command runs
(in seconds) is helpful.
