9cc9e091ed ktest: Detect typos in option names
It becomes quite annoying when you go to run a test and then
realize that you typed an option name wrong, and the test starts
doing the default action and not what you expected it to do.

It is even more annoying when you wake up the next day after
running the test over night when you discover this.

By testing if all options specified in a config file are
used by either ktest or were used in one of the option's values
we can see if there are any dangling options that were not used.
In such a case, show the user the options that were not used
and ask them if they want to continue or not.

The option IGNORE_UNUSED was also added to allow the user to
override this feature.

b5f4aea687 ktest: Have all values be set by defaults
Currently the patchcheck, bisect, and config_bisect variables
are only able to be set per test. You can not set a default
value for them.

By letting default values be set, it makes some config files
a bit easier, and also makes it easier to find typos in the
option names.

4f43e0dcaf ktest: Change initialization of defaults hash to perl format
Initializing each default value by specifying the hash name is
ugly. This is one of the rare cases that the "perl way" is actually
much cleaner and easier to read.

bc7c580377 ktest: Add options SWITCH_TO_GOOD and SWITCH_TO_TEST
For machines that do no use grub, it may be needed to update an
external image (tftp) before doing a reboot into either the
test image or the known good image.

The option SWITCH_TO_GOOD is added, where if it is defined, the
command that is specified as its value will be executed before
doing a reboot into a known good image.

The option SWITCH_TO_TEST is added, where if it is defined, the
command that is specified as its value will be executed before
doing a reboot into the test image.

c5dacb88f0 ktest: Allow overriding bisect test results
When running the ktest git bisect test, if the BISECT_TYPE is "test",
the bisect is determined to be good or bad based off of the error
code of the test that is run. Currently, if the test returns 0,
it is considered a pass (good), a non-zero is considered a fail (bad).

But it has been requested to add more options, and also change
the meanings of the error codes of the test. For example, one may
want the test to detect if the commit is not good or bad,
(maybe the bisect came to a point where the code in question
does not exist). The test could report an error code that should tell
ktest to skip the commit.

Also, a test could detect that something is horribly wrong and the
biscet should just be aborted.

The new options:

 BISECT_RET_GOOD
 BISECT_RET_BAD
 BISECT_RET_SKIP
 BISECT_RET_ABORT
 BISECT_RET_DEFAULT

have been added. The first 4 take an integer value that will
represent if the test should be considered a pass, fail, neither
good nor bad, or abort respectively.

The BISECT_RET_DEFAULT will bo whatever is not defined by the
above codes. If only BISECT_RET_DEFAULT is defined, then all tests
will do the default.

c4261d0f62 ktest: Ask for type of test when creating a new config
When no argument is supplied to ktest, or the config applied does
not exist and a new config is being created, instead of just using
the default test type, give the user an option to pick the test type
of either 'build, install, or boot'. Other options may be added later
but then those would require more questions as they require more
fields. But that's for another release of ktest to add that feature.

08aa0d1f37 perf tools: Add x86 RDPMC, RDTSC test
Implement a simple test for the self-monitoring data from the
perf mmap data area control page:

 6: x86 rdpmc test:

             0:           6053
             1:          60053
             2:         600059
             3:        6000059
             4:       60000075
             5:      600000247
    Ok

The counts are expected to increase monotonically - these
are recovered via RDPMC, without calling into the kernel.

It might be nice to add logic to automagically turn these numbers into OK/FAIL.

301b195db1 perf evlist: Fix errno value reporting on failed mmap
On failure, perf_evlist__mmap_per_{cpu,thread} will try to munmap()
every map that doesn't have a NULL base. This will fail with EINVAL if
one of them has base == MAP_FAILED, clobbering errno, so that
perf_evlist__map will return EINVAL on any failure regardless of the
root cause.

Fix this by resetting failed maps to a NULL base.
