[PATCH 0/3] minor fixes and supplement for ptdesc

[Qi Zheng <zhengqi.arch@bytedance.com>]

Hi all,

In this series, the [PATCH 1/3] and [PATCH 2/3] are fixes for some issues
discovered during code inspection.

The [PATCH 3/3] is a supplement to ptdesc conversion in s390, I don't know
why this is not done in the commit 6326c26c1514 ("s390: convert various pgalloc
functions to use ptdescs"), maybe I missed something. And since I don't have an
s390 environment, I hope kernel test robot can help compile and test, and this
is why I did not fold [PATCH 2/3] and [PATCH 3/3] into one patch.

Comments and suggestions are welcome.

Thanks,
Qi
