I still have troubles to understand your numbers

static allocation:
92274688 bytes -> 25165824 bytes

I assume that the first numbers refers to the static allocation for the
given amount of memory while the second one is the dynamic after the
boot, right?

No, first number refers to the static allocation before the patch and
second one is for after the patch.

I guess we are both talking about the same thing in different words. All
the allocations are static before the patch while all are dynamic after
the patch. Your boot example just shows how much dynamic memory gets
allocated during your boot. This will depend on the particular
configuration but it will at least give a picture what the savings might
be.
