Commit 214496cb18700fd7 ("ia64: make SPARSEMEM default and disable
DISCONTIGMEM") removed the last enabler of ARCH_DISCONTIGMEM_DEFAULT,
hence the memory model can no longer default to DISCONTIGMEM_MANUAL.

DISCONTIGMEM_MANUAL depends on ARCH_DISCONTIGMEM_ENABLE, which in turns
depends on BROKEN, so probably all discontig memory support can be
removed, too?

I'm planning to remove DISCONTIGMEM entirely after 2 or 3 releases to let
the dust settle a bit after the last users of DISCONTIGMEM were switched to
other memory models.
