[PATCH] mm: remove inline from scan_swap_map

[PATCH] mm: remove inline from scan_swap_map

[Cesar Eduardo Barros]

scan_swap_map is a large function (224 lines), with several loops and a
complex control flow involving several gotos.

Given all that, it is a bit silly that is is marked as inline. The
compiler agrees with me: on a x86-64 compile, it did not inline the
function.

Remove the "inline" and let the compiler decide instead.
