It's available on https://github.com/Naoya-Horiguchi/mm_regression.
The README is a bit obsolete (sorry about that ...,) but you can run
the testcase like below:

  $ git clone https://github.com/Naoya-Horiguchi/mm_regression
  $ cd mm_regression
  mm_regression $ git clone https://github.com/Naoya-Horiguchi/test_core 
  mm_regression $ make
  // you might need to install some dependencies like numa library and mce-inject tool
  mm_regression $ make update_recipes

To run the single testcase, run the commands like below:

  mm_regression $ RECIPEFILES=cases/page_migration/hugetlb_migratepages_allocate1_noovercommit.auto2 bash run.sh
  mm_regression $ RECIPEFILES=cases/cases/mce_ksm_soft-offline_avoid_access.auto2 bash run.sh

You can run a set of many testcases with the commands like below:

  mm_regression $ RECIPEFILES=cases/cases/mce_ksm_* bash run.sh
  // run all ksm related testcases. I reproduced the panic with this command.

  mm_regression $ run_class=simple bash run.sh
  // run the set of minimum testcases I run for each releases.

Hopefully this will help you.

Thanks,
