This uses struct pgtable_debug_args in the basic test functions. There
are more cleanups applied:
* Move hugetlb_basic_tests() so that the basic tests are treated
as a bundle.
* Drop parameters to {pgd, p4d}_basic_tests() as they're never
used.
* Drop unused variables @{pgd, p4d}_aligned in debug_vm_pgtable().

Please dont move this test as it is placed near to the THP functions.
Also please don't club any non-related changes here while converting
various tests into this new arg structure.

Right, they are not getting used right now. But then it might be just
better to replace them with this new structure in order not to do any
unrelated changes.

Yes. I won't move hugetlb_basic_tests() around in v4.

Sure. I will pass &args to these two functions in v4, even they are
not used. Hopefully, I understand your comments correctly.
