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.
