I wrote: [use make 'COPTFLAGS=-O -malign-loops=0 -malign-jumps=0 -malign-functions=0 -fomit-frame-pointer' to shrink the kernel] I just tried this with a 3.0-RELEASE GENERIC kernel. Unfortunately, the text space only shrunk by 3000 bytes :-(. I would have expected quite a bit more. [One problem is that the text space within object files is padded to a 16-byte boundary - this is probably worth ~2.5K, but can't be recovered using the standard toolchain AFAIK]. There is, however ~130K of text strings in the kernel - 3-4K of which is duplicate. Maybe we need to look at how much of this is necessary.
