mm: swap_cgroup: allocate swap_cgroup map using vcalloc()
Currently swap_cgroup's map is constructed as a vmalloc()'s-based array of
pointers to individual struct pages. This brings an unnecessary
complexity into the code.
This patch turns the swap_cgroup's map into a single space
allocated by vcalloc().
