UML has some header magic that expects a non-inline __kmalloc() function to be
available. Fixes the following link time errors:
arch/um/drivers/built-in.o: In function `kmalloc':
/home/penberg/linux-2.6/arch/um/include/um_malloc.h:14: undefined reference to
`__kmalloc'
/home/penberg/linux-2.6/arch/um/include/um_malloc.h:14: undefined reference to

Matt, does this look ok to you? Can we merge it via Christoph's tree?
