[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
