Yeah I was also not interested for the longest time because when I became concerned when I looked at the code generated by sparsemem for virt_to_page and page_address. But that is different now. > Since I've no machines which use the present discontig support and > have more than a single bank of memory, I've no way to test and > progress sparsemem on ARM - and since no one's interested I'm probably > going to drop the ARM sparsemem git branch soon. Could you keep it around for a while longer? sparse_virtual now allows code reduction in page_address and virt_to_page even vs. discontig. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
