Yes, eventually.

My initial intention a few month ago was to remove the ugly casts [1], but
then willy pointed out that Linus objected to something like this [2] and
it looks like more than a decade old technical debt.

Since there are more than 600 or those it will take a while to convert
suitable gfp calls to kmalloc.
Afterwards we can re-evaluate what APIs we want to provide for allocations
that must have actual pages.
