This series contains some cleanups and new test suggestions from Catalin
from an earlier discussion.

https://lore.kernel.org/linux-mm/20201123142237.GF17833@gaia/

This series is based on v5.10-rc6 and has been tested on arm64 and x86 but
has only been build tested on riscv, s390, arc etc. It would be great if
folks could test this on these platforms as well. Thank you.

Hello Gerald/Christophe/Vineet/Paul,

Could you please give this series a quick test on s390, ppc, arc,
and riscv platforms. Thank you.
