[PATCH v3 0/9] um: Minor fixes and cleanups

[Tiwei Bie]

A series of minor fixes and cleanups for UML.

Most changes in this series are very straightforward. Please consider
picking this series for v6.9.

There are still some remaining -Wmissing-prototypes warnings. I plan to
send a followup RFC series first to fix those warnings.

Feedbacks on this series would be appreciated. Thanks!

Changes since v2:
