This is a bunch of LKDTM clean-ups to improve and expand testing,
given feedback from testing at kernelci.org. Adds a few new tests as
well.

(If a pull-request is preferred, please let me know.)

Thanks!

-Kees

This whole series was tested on top of next-20210623, here are a
couple of sample results from KernelCI staging:

Clang 13 on AMD x86_64:
https://staging.kernelci.org/test/plan/id/60d4a5ce3d2bc535d924bf25/

GCC 8 on Intel x86_64:
https://staging.kernelci.org/test/plan/id/60d570711a3d6beefe24bf26/

And this is where the series was applied:

Thanks,
