Please read Documentation/SubmittingPatches
(umm, make that Documentation/process/submitting-patches.rst)

Make sure to send the patch to yourself only until
you know you can apply it correctly and then send
it to the mailing list.

btw:

This should probably be a series of 4 patches, each
single patch doing one of the things listed above.

And do please use checkpatch on your proposed patches.
