It was pointed out to me by my colleague Yamahata-san that neither sparse nor discontig mem compile without NUMA support. Cc: Alex Williamson <alex.williamson@xxxxxx> Cc: Isaku Yamahata <yamahata@xxxxxxxxxxxxx> Signed-off-by: Simon Horman <horms@xxxxxxxxxxxx> --- This seems line an issue best solved by prohibiting such settings through Kconfig. But if it is desirable for sparse and discontig memory to work without CONFIG_NUMA let me know and I'll have a stab at it. It does seem possible code-wise. I'm just not sure if its useful.
