From: Tim Gore <tim.gore@intel.com>

For some tests that put pressure on memory, the Android
lowmemorykiller needs to be disabled for the test to run to
completion. The first patch is a simple bit of preparation
to ensure that all (well written) "simple" tests exit via a
call to igt_exit, in the same way as tests with subtests do.
This is to make sure we can clean up by re-enabling the
lowmemorykiller.
The second patch is to disable the Android lowmemorykiller
during the common initialisation code (in oom_adjust_for_doom
to be exact) and to re-enstate it in igt_exit.

v1: As above

v2: Remove the call to disable the lowmemorykiller from
oom_adjust_for_doom. lowmemorykiller is not disabled
by default now; it is up to each individual test to
call low_mem_killer_disable() if it needs to.

Tim Gore (2):
lib/igt_core: make single/simple tests use igt_exit
lib/igt_core.c: add function to disable lowmemorykiller
