This is not entirely accurate. Look at _how_ the new upper limits where
determined in commit e638072e6172. This should build just fine:

	$ make defconfig
	$ ./scripts/config -e PROVE_LOCKING --set-val LOCKDEP_BITS 24
	$ make -s olddefconfig all

Is it not the case for you? My guess is that you've also changed _other_
configs and combined with that you hit the limit. If not, can you please
provide the steps and commit you are using?

Thanks,
