The IXP4xx kernel for 2.6.29 has jumped 85 KB in size (1105K on
2.6.27.8, vs 1190K for 2.6.29). The defconfig is the same, or as nearly
as I can make it (make ARCH=arm oldconfig, answer "N" to everything).
Anyone else observed this, or have I missed something?

It does this pretty much every kernel release :( Quite depressing.

Yes. And it get's worse when gcc 4.4 will be "mainline".
On my debian unstable box, I installed gcc-4.4/g++-4.4 packages
from the "experimental" repository. All (user-space) programs
that I compiled with this new compiler gained considerably in
size.
For the kernel: there's scripts/bload-o-meter, so you compare to
kernel images and find out which functions are responsible for
the bloat.
