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.
