Most of them share quite some code, some of them are completely identical. This series implements a generic version of this function and migrates almost all architectures to it. This patch: Most show_mem() implementations calculate the amount of pages within the swapcache every time. Move the output to a more appropriate place and use the anyway available total_swapcache_pages variable.
