This was considered and abandoned for 2.0. The top-level makefile says:
We don't want to have this in the config file because it makes re-config very ugly and too many fundamental files depend on CONFIG_SMP.
I gather the problem is that putting in CONFIG_SMP would make lots of files in include/asm/*.h depend on include/linux/autoconf.h, which would make almost the whole kernel depend on include/linux/autoconf.h.
I think it would be a good thing to split include/linux/autoconf.h into a whole directory full of files, include/config/*.h, with one symbol per file. This would solve the whole problem and allow CONFIG_SMP to be just another symbol. It would still force a lot of recompilation to change CONFIG_SMP but the system but it would force less recompilation than now, and the system would be more regular.

Please don't touch ext2fs. Make a new all-singing all-dancing ext3fs if you want. I like my stable ext2fs file system.
I did a word count on the fs/ext2 directory and it's only 5142 lines. Copy that into fs/ext3 and have at it.
I favor the rest of the items on your list.
