Lance Yang f734944e12 selftests/mm: skip soft-dirty tests when CONFIG_MEM_SOFT_DIRTY is disabled 
commit 0389c305ef upstream.

The madv_populate and soft-dirty kselftests currently fail on systems
where CONFIG_MEM_SOFT_DIRTY is disabled.

Introduce a new helper softdirty_supported() into vm_util.c/h to ensure
tests are properly skipped when the feature is not enabled.
