This series implements the sw_sync test and the lib/sw_sync helper functions
for said test.

Gustavo Padovans sw_sync series was just de-staged in
gregkh-staging/staging-next [1], and this test is targeted at verifying the
functionality implemented in that series.

The sw_sync subtests range from very basic tests of the sw_sync functionality,
to stress testing and randomized tests.
