Hi,
What makes you say that some of these are unnecessary?

Please use Rule #1 from Documentation/process/submit-checklist.rst:

1) If you use a facility then #include the file that defines/declares
   that facility.  Don't depend on other header files pulling in ones
   that you use.


so just because it will compile without these headers being explictly
#included does not mean that you should remove them.

above is used by __init and __exit.

Looks OK to remove poll.h.

Might be OK for sched.h.

Might be OK for wait.h.

I didn't check the others.
