If the system has more than one swap device and swap device has the node
information, we can make use of this information to decide which swap
device to use in get_swap_pages() to get better performance.
The current code uses a priority based list, swap_avail_list, to decide
which swap device to u

Resend:
This is a resend, the original patch doesn't catch much attention.
It may not be a big deal for swap devices that used to be hosted on
HDD but with devices like 3D Xpoint to be used as swap device, it could
make a real difference if we consider NUMA information when doing IO.
