*raised eyebrow*

You do realize that kmalloc() gives physically contiguous allocation, right?
And refuses to allocate more than KMALLOC_MAX_SIZE, while we are at it.
With allocations anywhere near such range being very heavily discouraged.

There might or might not be point in using size_t for kmalloc() argument,
but "future-proofing" isn't it.
