Subject: [PATCH] mm: Remove default DISCONTIGMEM_MANUAL

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.

Signed-off-by: Geert Uytterhoeven <geert@...ux-m68k.org>
---
DISCONTIGMEM_MANUAL depends on ARCH_DISCONTIGMEM_ENABLE, which in turns
depends on BROKEN, so probably all discontig memory support can be
removed, too?
