I looked at implementing linear pagetable mappings for x86 as a way of getting rid of CONFIG_HIGHPTE, and to make pagetable manipulations generally more efficient. I gave up on it after a while because all the existing pagetable accessors are not suitable for a linear pagetable, and I didn't want to have to introduce a pile of new pagetable interfaces. Would the PTI interface be helpful for this? Thanks, J -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
