Not much changed:
text data bss dec hex filename
845924 51204 78896 976024 ee498 linux-2.5.x/vmlinux-inline
840368 48392 78896 967656 ec3e8 linux-2.5.x/vmlinux-noinline
By the way: this is uClinux 2.5.75-uc0. 2.6.0-test1 should be very close.
I'm building with gcc 3.3.1-pre with some ColdFire/uClinux patches.

Neither did it change much here:
text data bss dec hex filename
224145 6952 5468 236565 39c15 linux-2.5.x/fs/built-in.o.inline
223591 6952 5468 236011 399eb linux-2.5.x/fs/built-in.o

845924 51204 78896 976024 ee498 linux-2.5.x/vmlinux-inline-O2
819276 52460 78896 950632 e8168 linux-2.5.x/vmlinux-inline-Os
text data bss dec hex filename
840368 48392 78896 967656 ec3e8 linux-2.5.x/vmlinux-noinline-O2
815052 48316 78896 942264 e60b8 linux-2.5.x/vmlinux-noinline-Os
This is quite a saving! I'll send a patch to Greg (uClinux maintainer)
once I've tested it a bit more.
NOTE: I just noticed the 2.4.x kernel was built with -O1 because I
had symbolic debug enabled. That's not fair: 2.4.20 would probably
come out even smaller than I reported!
