[PATCH] create mm/Kconfig for arch-independent memory options
With sparsemem being introduced, we need a central place for new
memory-related .config options: mm/Kconfig. This allows us to remove many
of the duplicated arch-specific options.
The new option, CONFIG_FLATMEM, is there to enable us to detangle NUMA and
DISCONTIGMEM. This is a requirement for sparsemem because sparsemem uses
the NUMA code without the presence of DISCONTIGMEM. The sparsemem patches
use CONFIG_FLATMEM in generic code, so this patch is a requirement before
applying them.
Almost all places that used to do '#ifndef CONFIG_DISCONTIGMEM' should use
'#ifdef CONFIG_FLATMEM' instead.
