We expend that people that run the tests have the configs as contained in
tools/testing/selftests/mm/config
enabled.
I'm fine with teaching the tests that that is no longer required.
Should we then remove
CONFIG_TRANSPARENT_HUGEPAGE=y
from the file, or leave it in there for people building their configs to
know what to enable for best test coverage? (I doubt people do use it
for that purpose)
