That is great!

But the commit log contains no motivation whatsoever why this is such
a good thing, so perhaps one of you can enlighten us? This endless
fiddling with boot-time memory reservations doesn't make the system
more robust, so having a good reason in the commit log why this change
is needed is really needed.
