Rework the commented things in a new branch.

Apply the patches to the new branch one at
a time, modify as necessary then
git commit --amend
the appropriately changed files while modifying
change logs.

Then resubmit with
	git format-patch --subject-prefix="PATCH V2"
You could also add --in-reply-to=originalemailid

A new patch would be fine.
Here's a little regex based tool for part of that conversion
http://lwn.net/Articles/380161/

An example would be:
$ ./scripts/cvt_kernel_style.pl			\
	--convert=convert_printk_to_pr_level	\
	-o drivers/staging/xgifb/XGI_main_26.c
