I usually just edit the net/ipv6/Kconfig before building UML version of
the HIPL kernel. You remove the "select PREEMPT" line from the "config
HIP" stanza. You also need to remove the X86_PC and REGPARM elements
from the "depends" line. I guess this could be worked into the Kconfig
file but I know too little about the syntax to do it myself.
