As per latest licensing doc [1], It quotes that GPL  is same as GPL v2 and GPL
v2 exists only for historical reasons as shared below :

“GPL v2 Same as “GPL”. It exists for historic reasons."

So I think it should be fine and more apt to use GPL. This is also highlighted
in below commit:
bf7fbeeae6db644ef5995085de2bc5c6121f8c8d module: Cure the MODULE_LICENSE "GPL"
vs. "GPL v2" bogosity

It includes all the other required headers (including those you mentioned
below), and header list is probably copied from other files in same directory.
But it does suffice the requirements as I have verified the compilation.

All the above headers are already included as part of kernel.h

Kindly let me know if any queries.
