Don't check for pte swap entries when CONFIG_SWAP=n.
And save 'present' in the vec array.

mm/built-in.o: In function `sys_mincore':
(.text+0xe584): undefined reference to `swapper_space'

What you've done there is fine, Randy, thank you.

Can't you have migration without swap?

But I just got out of bed to take another look, and indeed:
what is it doing in the none_mapped !vma->vm_file case?
passing back an uninitialized vector.

I must have completely forgotten about the vector :(
