[PATCH] enable sparsemem without CONFIG_NUMA

From: Jeff Chua

Linus,

While testing for more than 8 cpus, I couldn't select sparsemem when CONFIG_X86_GENERICARCH is selected instead of CONFIG_X86_PC.

Here's a patch to enable sparsemem independent of NUMA instead of just flatmem ... unless there a reason for sparsemem to depend on NUMA for more than 8 CPUs?


Thanks,
Jeff
