Hi Max,
Thanks for the patch. Just wondering if you ran with different config
options (which might impact test case selection) on/off during testing ?

I went through the code in the mm/debug_vm_pgtable.c and saw that most
variations are related to the huge page support which xtensa doesn't have.
I've tested it with and without CMA.
I haven't found anything else interesting that I could tweak -- have I missed
anything?

Thanks.
