| |
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
