Actually this is the kernel memory, but not user memory. Otherwise
virt_to_phys() doesn't make sense. You copied the user data to kernel memory in
the last patch. So whether user memory is aligned doesn't matter, and in last
patch, you have guaranteed the alignment is met during kernel memory allocation.
I mean't user of this API (not user space). But I agree with your
comments.
