I fixed the problem via another way.

At startup I use a statically allocated area, or
the bootmem allocated page.

The kmalloc is used only when a request for memory
cannot be satisfied by this memory.

I will probably post the patch for the hostmem today,
followed tommorow by the patch for the dpmem.

Stay tuned.
