Hi Phillipe,
	In trying to build xenomai 2.4.4 into the 2.6.26 kernel, using the 
default kconfig, I get

   CC      kernel/xenomai/arch/generic/hal.o
   LD      kernel/xenomai/arch/generic/xeno_hal.o
   LD      kernel/xenomai/arch/generic/built-in.o
   LD      kernel/xenomai/arch/built-in.o
   CC      kernel/xenomai/nucleus/heap.o

function 'class_device_create'

from integer without a cast
kernel/xenomai/nucleus/heap.c: In function 'xnheap_umount':

You mentioned the maintenance branch, where can I find that?
