set-timer-lat
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.

POSIX says that exit takes an unsigned integer between 0 and 255, so
using -1 doesn't work on POSIX shells.
There is already a well-defined failure code, $FAIL (1), so use that.

If the stack tracer (CONFIG_STACK_TRACER) is disabled, the
fgraph-filter-stack test blows chunks:

+ echo nop
./ftracetest: 19: /home/michael/selftests/ftrace/test.d/ftrace/fgraph-filter-stack.tc:

Fix it by checking if the proc file exists before echoing to it. With
the patch applied it fails correctly with:

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 patch splits rtc.txt into two separate files, one for the
documentation itself, and the other for the rtctest.c file. The rtctest
file is moved into the kernel tools/testing/selftests/timers directory.
This will make automated testing easier. Note that the only difference in
the rtc.txt file is that the location of the rtctest.c file has changed.

The bulk of the selftests are actually below the powerpc sub directory.
This adds support for installing them, when on a powerpc machine, or if
ARCH and CROSS_COMPILE are set appropriately.
This is a little more complicated because of the sub directory structure
under powerpc, but much of the common logic in lib.mk is still used. The
net effect of the patch is still a reduction in code.

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.

Adds the set-2038 test which sets the time to near-edge cases
like the start and end of the 32 bit epoch and checks that
time behaves properly. There is also a dangerous mode, which
lets the clock roll over past 2038 on 32bit systems, which
on some older kernels will cause system hangs.

This adds my clock skew estimation test from the timetest suite.
It measures the drift between CLOCK_MONOTONIC and CLOCK_MONOTONIC_RAW
and compares it with the current frequency value from adjtimex.
It sometimes can trigger false failures when ntpd isn't in a
steady state, but its a useful too when doing adjtimex testing.

The posix_timers.c test has a loop that tries to keep it in
kernel space, repeatedly calling brk(). However, it doesn't
check the return value, which causes warnings.
This patch adds a err value which captures the return value
and modifies the test so it will quit if a failure occurs.

Several tests that rely on implicit build rules fail to build,
when invoked from the main Makefile kselftest target. These
failures are due to --no-builtin-rules and --no-builtin-variables
options set in the inherited MAKEFLAGS.
--no-builtin-rules eliminates the use of built-in implicit rules
and --no-builtin-variables is for not defining built-in variables.
These two options override the use of implicit rules resulting in
build failures. In addition, inherited LDFLAGS result in build
failures and there is no need to define LDFLAGS. Clear LDFLAGS
and MAKEFLAG when make is invoked from the main Makefile kselftest
target. Fixing this at selftests Makefile avoids changing the main
Makefile and keeps this change self contained at selftests level.

When annotating source/disasm lines the perf tools parse the output of
objdump, trying to provide augmented output that allows navigating
jumps, calls, etc.
But when a line output by objdump can't be parsed the annotation code
falls back to just presenting the unparsed line.
When fixing a leak in the 0fb9f2aab738 commit ("perf annotate: Fix
memory leaks in LOCK handling") we failed to take that into account and
instead tried to free one of the data structures that should be freed
only when successfully allocated, oops, segfault.
There was a change in the way the objdump output for lock prefixed
instructions is formatted that lead the relevant parser to fail to grok
it.
At least RHEL7 works ok, but Fedora 20 segfaults.
Fix it by making the ins__delete() destructor work like the most basic
destructor: free().
Namely make it accept a NULL pointer and when handling it just do
nothing.
Further investigation is needed to figure out the nature of the objdump
output change so as to make the parser grok it.

On systems which don't implement sys_execveat(), this test produces a
lot of output.
Add a check at the beginning to see if the syscall is present, and if
not just note one error and return.
When we run on a system that doesn't implement the syscall we will get
ENOSYS back from the kernel, so change the logic that handles
__NR_execveat not being defined to also use ENOSYS rather than -ENOSYS.

This reverts commit 5c1de006e8e66b0be05be422416629e344c71652.
While the original commit makes it easier to run cpupower from the
local build directory, it also leaves the binary with a rather poor
rpath of './' in it after it is installed on a system via 'make install'.
This is considered bad practice and can cause cpupower to fail in
rpmbuild with the following error:
ERROR 0004: file '/usr/bin/cpupower' contains an insecure rpath './' in [./]
error: Bad exit status from /var/tmp/rpm-tmp.A6u26r (%install)
Bad exit status from /var/tmp/rpm-tmp.A6u26r (%install)
Developers should be able to use LD_LIBRARY_PATH to achieve the same
effect and not introduce rpath into the binary.

gcc complains about the 'cols' variable being unused. This is
unavoidable, given the ncurses getmaxyx() macro-based API, which wants
to assign to a variable directly, even when we're not going to use it.
Warning:

Some distros (e.g., Arch Linux) don't package the tinfo library
separately from ncurses, so don't unconditionally include it. Instead,
use pkg-config.
The $(STATIC) ugliness is to handle the reported build case from commit
6b533269fb25 ("tools/thermal: tmon: fix compilation errors when building
statically"), where a developer wants to be able to build with:
make LDFLAGS=-static
which requires an additional pkg-config flag.
Finally, support a lowest common denominator fallback (-lpanel
-lncurses) for build systems that don't have pkg-config entries for
ncurses.

We might want to prepare CFLAGS outside of this Makefile, so don't
overwrite its initial value.
Then, support $(CROSS_COMPILE), so we can use a cross-compile toolchain.

The number of rows in the dialog vary according to the number of cooling
devices. However, some of the windowing computations were assuming a
fixed number of rows. This computation is OK when we have between 4 and
9 cooling devices (and they wrap to the next column), but with fewer
devices, we end up printing off the end of the window.
This unifies the row computation into a single function and uses that
throughout the TUI code. This also accounts for increasing the number of
rows when there are more than 9 total cooling devices.

We can use the ncurses API to get the number of rows.

If we launch in daemon mode (--daemon), we don't have the ncurses UI,
but we might want to set the target temperature still. For example,
someone might stick the following in their boot script:
tmon --control intel_powerclamp --target-temp 90 --log --daemon
This would turn on CPU idle injection when we're around 90 degrees
celsius, and would log temperature and throttling info to
/var/tmp/tmon.log.

The recent build changes cause perf to not compile for sparc64 since the
arch/sparc64/Build file does not exist:
/home/dahern/kernels/linux.git/tools/build/Makefile.build:40: arch/sparc64/Build: No such file or directory
Fix by converting the sparc64 RAW_ARCH to sparc ARCH -- similar to what
is done for x86_64.
