Christoph,
With commit 1759415e you've removed all #ifdef CONFIG_CMPXCHG_LOCAL's from slub. This change breaks slub (again) on UML. UML does not implement this_cpu_cmpxchg16b_emu().
Starting with 2.6.39 (commit 084189a) I've disabled CONFIG_CMPXCHG_LOCAL on UML do bypass the issue. This fix does no longer help.
Is there anything I can do to have slub on UML? Implementing this_cpu_cmpxchg16b_emu for UML is not really an option. See: http://comments.gmane.org/gmane.linux.kernel/1125183
Thanks, //richard
