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
