OK, in below commit the including order is adjusted, but the old one was
not removed.
commit 65fddcfca8ad("mm: reorder includes after introduction of linux/pgtable.h")

Could you rephrase the commit log? , the below sentences is for your reference.

============
In crash_dump.h, header file linux/pgtable.h is included twice. This
duplication was introduced in commit 65fddcfca8ad("mm: reorder includes
after introduction of linux/pgtable.h") where the order of include is
adjusted, while the old one was not removed.

Clean it up here.
============

Thanks for fixing this. when you finish polishing the patch log, please
feel free to add:
