But I done two mistakes in it. Benjamin pointed out after one msec that
there was no need for putting the address on the stack, and looking a
_bit_ more at swap_out_pmd() I noticed that the old code was just updating
swap_address, woops ;).
I noticed the second very more important mistakes running at 8Mbyte
because the trashing memory proggy was segfaulting. The bug was to base
the maximal weight of swap_out() on the total_rss and not on the sum of
the total_vm of all processes. With 8Mbyte all my processes got swapped
out and so swap_out stopped working ;). It's fixed now...

This change is pretty buggy too. The only good thing was to not care
about the pgcache min limits before to shrink the _swap_cache_. Now I also
changed pgcache_under_min to don't care about the swapcache size (now the
swap cache is a bit more fast-variable/crazy).

Hmm I guess at least the brw_page set_bit was not needed because before to
run such function is been run or a __find_page() or an add_to_...cache().

Also some count should be moved from int to unsigned long to handle huge
RAM sizes.

Here Steve's feedback:
128MB 8MB
------- -------
Your previous patch: 132 sec 218 sec
This patch : 118 sec 226 sec
Even if `This patch' was pretty buggy (as pointed out above) it was going
sligtly _faster_. I guess the reason for the 8Mbyte slowdown was the
s/rss/total_vm/ thing (but I am not 100% sure).
I fixed the bugs and so I repost the fixed diff against pre4. I also
cleaned up a bit some thing...
