We will soon require more sophisticated methods to replace single instructions with multiple instructions. We do that by branching to a memory region where we write replacement code for the instruction to. This region needs to be within 32 MB of the patched instruction though, because that's the furthest we can jump with immediate branches. So we keep 1MB of free space around in bss. After we're done initing we can just tell the mm system that the unused pages are free, but until then we have enough space to fit all our code in.
