SubjectSuccess report:[CFT][PATCH] hogstop + eatcache fixes 2.4.12-ac3

I have found the above patch to provide _massive_ performance/responsivity gains in everyday, workstation use.

1.2Ghz Athlon in abit KT7A board

Typical session uses:
- ximian gnome 1.4
- multiple nautilus windows
- multiple mozilla windows
- staroffice
- Forte IDE (Sun, Java)
- Evolution PIM
- large image manipulation in GIMP
- kernel recompiles
- dd'ing and burning of CD images
- mp3 streaming.

Up until now the system has swapped prematurely (failing to dump the disk cache left over after e2fsck on reboot), has become very unresponsive and mp3 playback often breaks up.

With this patch I am unable to get mp3 playback to break up, with all but the most excessive loads (fork of death, "ls -w 100000" etc). It is really nice to see memory being freed up in advance of it being needed, so that the system is not reduced to thrashing when loading a heavy weight app like Forte.

Good work Rik; this is 2.4 vm/mm as it should be. A good iterative step for the next 2.4 -ac patch :)
