Try to find a kfree implementation that doesn't need virt_to_page().
This is a big restriction of the current implementation: It's in the hot
path, but the operation is only fast on simple systems, not on numa
systems without a big memory map.
And it makes it impossible to use vmalloc memory as the basis for slabs,
or to use slab for io memory.
