As I already answered privately - I do have them right now. And those patches were not mine. Most of them was collected right on lkml or from digests on lwn.net.
[ I was playing only with network code - and I was concerned with performance more, than with image size. And had no luck achiving something. ]

Okay. I have found it. But I cannot find how it is used. I have grepped thru 2.6.0-test0 - but I can find only entries in defconfigs - but no mentions in .h/.c files. What I'm missing?
And yes - this option doesn't work in 'make menuconfig'.

Correct me if I'm wrong. I was just poking around 'small is beatiful'.
P.S. To my earlier 'far from vanilla' comment (-x '.*' - to skip .depend/.config/etc): $ diff -urN -x '.*' ./linux-2.4.17 \ /opt/hardhat/devkit/lsp/ibm-walnut-ppc_405/linux-2.4.17_mvl21\ | wc -l 1128089 $ and more than 500 additional CONFIG_* parameters comparing to vanilla.
