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.

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.

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.

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.

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.

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.

Typing in a full path when you know that the path exists within
the directory your are running is tedious and unnecessary.
Allow the user to use ${PWD} if they want a dynamic path name
which will be the path that ktest.pl is executed from
or use ${THIS_DIR} which is a variable assigned `pwd` and
the the variable will exist within the config, allowing the user
to change it and affect all other paths using this variable as well

When a user runs ktest without an argument, or the argument given
is not a config file that exists, ktest will ask the user a few
questions to create a simple ktest config file.
A few of the questions should have a default value set, that if anything
it will make it easier for the user to know what is suppose to
be in that value.
These new values are:
SSH_USER, BUILD_TARGET and TARGET_IMAGE

Let's say we have "OUTPUT_DIR = build/${TEST_NAME}", and we're iterating
a test. In the second iteration of a test, the TEST_NAME of the test
we're repeating is not used. Instead, ${TEST_NAME} appears literally:
touch /home/rabin/kernel/test/build/${TEST_NAME}/.config ... SUCCESS
Fix this by making __eval_option() check the parent test options
for a repeated test.

Commit 8dc7a9c84 ("blackfin: Add export.h to files using
EXPORT_SYMBOL/THIS_MODULE") inserted some of the include statements into
sections protected by an unrelated #if CONFIG_... statement. This can cause,
depending on the configuration used, warnings like this one:
arch/blackfin/mach-bf537/boards/stamp.c:2940: warning: data definition has no type or storage class
arch/blackfin/mach-bf537/boards/stamp.c:2940: warning: type defaults to ‘int’ in declaration of ‘EXPORT_SYMBOL’
arch/blackfin/mach-bf537/boards/stamp.c:2940: warning: parameter names (without types) in function declaration
This patch fixes it by moving the includes out of the #if protected sections.

Commit 31a3ddda166cda86d2b5111e09ba4bda5239fae6 introduced
a use after free in virtio-pci. The main issue is
that the release method signals removal of the virtio device,
while remove signals removal of the pci device.
For example, on driver removal or hot-unplug,
virtio_pci_release_dev is called before virtio_pci_remove.
We then might get a crash as virtio_pci_remove tries to use the
device freed by virtio_pci_release_dev.
We allocate/free all resources together with the
pci device, so we can leave the release method empty.

After commit e978aa7d7d57 ("cpuidle: Move dev->last_residency update to
driver enter routine; remove dev->last_state") setting acpi_idle_suspend
to 1 by acpi_processor_suspend() causes the ACPI cpuidle routines to
return error codes continuously, which in turn causes cpuidle to lock up
(hard).
However, acpi_idle_suspend doesn't appear to be useful for any
particular purpose (it's racy and doesn't really provide any real
protection), so it can be removed, which makes the problem go away.

Real world year equals the value in vrtc YEAR register plus an offset.
We used 1960 as the offset to make leap year consistent, but for a
device's first use, its YEAR register is 0 and the system year will
be parsed as 1960 which is not a valid UNIX time and will cause many
applications to fail mysteriously. So we use 1972 instead to fix this
issue.
Updated patch which adds a sanity check suggested by Mathias
This isn't a change in behaviour for systems, because 1972 is the one we
actually use. It's the old version in upstream which is out of sync with
all devices.

drm_wait_vblank must be DRM_UNLOCKED because otherwise it
will grab the drm_global_mutex and then go to sleep until the vblank
event it is waiting for. That can wreck havoc in the windowing system
because if one process issues this ioctl, it will block all other
processes for the duration of all vblanks between the current and the
one it is waiting for. In some cases it can block the entire windowing
system.
v2: incorporate comments received from Daniel Vetter and
Michel Daenzer.
v3/v4: after a lengty discussion with Daniel Vetter, it was concluded
that the only thing not yet protected with locks and atomic
ops is the write to dev->last_vblank_wait. It's only used in a
debug file in proc, and the current code already employs no
correct locking: the proc file only takes dev->struct_mutex,
whereas drm_wait_vblank implicitly took the drm_global_mutex.
Given all this, it's not worth bothering to try to fix
the locks at this time.
