The only problem is it requires reservation of memory at boot, while vmalloc
and friends will try to get more memory from the system by freeing some
buffers, swapping out the code, etc.

So, if you do not know how much you will need, but you may need a lot,
vmalloc is the only solution. I am just advertising a few functions allowing
mmaping of vmalloced area to user space.
