Looks good. Thank you!

Thanks for working with me on this. Yes these were the more straight forward
conversions. The next set will require more review and I should have them
posted soon at least for RFC. Unfortunately, there are 2 places which are
proving difficult to follow the mapping orders required of kmap_local_page().
I'll open that discussion with the next round of conversions.

For now, thank you again,
Ira
