Thanks for pushing this, Geert.

Since 4a5fa3590f09 ([PARISC] slub: fix panic with DISCONTIGMEM) from 
2.6.39-rc4, you can't actually select slub on m68k without CONFIG_ADVANCED 
and CONFIG_SINGLE_MEMORY_CHUNK because it otherwises defaults to 
discontigmem.

James tested hppa64 with my N_NORMAL_MEMORY fix and found that it turned 
an SMP box into UP.  If you've tested slub on m68k without regressions, 
then perhaps you'd like to add a "|| M68K" to CONFIG_SLUB?
