Hi, is this expected change in memory usage after your patch?: (in init 5 stage, please note dipslayed the MemShared: memory value)

I have to say the -ac15+page_launder_patch kernel has turned on the extra debugging options in Kernel hacking menu. Otherwise all kernel params are same with the -ac15.
I was not able to reproduce memeory allocation errors during 20h run yesterday with -ac15 kernel using mysql tests and benchmarks. I'll try to do same today with this patched -ac15 kernel.
