Apparently, it is a problem with tlb/command pipeline/hell-knows-more

This may be "illusion", I frequently find that adding arbitrary extra
instruction or some random data can make bugs disappear. Usually it
is moving symbols in the kernel image and either:

1) avoiding some linker bug
2) restoring some alignment constraint which is needed

Your change for example may have moved __init section into place which
does not trip some bug in linker or something like this.

Experiment 8-)
