Most of the tests under selftests follow a pattern for their results,
which can then be parsed easily by other external tools easily. Though
futex tests do print the test results very well, it doesn't really
follow the general selftests pattern.
This patch makes necessary changes to fix that.

hmm_init calls hmm_alloc to set dummy_ptr, hmm_alloc calls
hmm_init when dummy_ptr is not yet set, which is the case in
the call from hmm_init, so it calls hmm_init again, this continues
until we have a stack overflow due to the recursion.
This commit fixes this by adding a separate flag for tracking if
hmm_init has been called. Not pretty, but it gets the job done,
eventually we should be able to remove the hmm_init call from
hmm_alloc.

[ 14.392257] (NULL device *): Failed to find gmin variable gmin_V1P8GPIO
We could switch to using pr_warn for dev == NULL instead, but as comments

a NULL device is a workaround for 2 specific evaluation boards, so

Capture driver silently overrides pixel format with a hack (according to
the comments) to pass v4l2 compliance tests. This isn't needed for
normal functionality, and works for composite video and raw camera capture
without.
In addition, the hack assumes that it only supports raw capture with a
single format (SBGGR8) which isn't true. VPIF can also capture 10- and
12-bit raw formats as well. Forthcoming patches will enable VPIF
input with raw-camera support and has been tested with 10-bit format
from the aptina,mt9v032 sensor.

hard disk IO latency varies a lot depending on spindle move. The latency
range could be from several microseconds to several milliseconds. It's
pretty hard to get the baseline latency used by io.low.
We will use a different stragety here. The idea is only using IO with
spindle move to determine if cgroup IO is in good state. For HD, if io
latency is small (< 1ms), we ignore the IO. Such IO is likely from
sequential IO, and is helpless to help determine if a cgroup's IO is
impacted by other cgroups. With this, we only account IO with big
latency. Then we can choose a hardcoded baseline latency for HD (4ms,
which is typical IO latency with seek). With all these settings, the
io.low latency works for both HD and SSD.
