    Doublewords to the right of the doubleword in which the
    highest-numbered facility bit is assigned for a model
    may or may not be stored.

However, stack protection in certain binaries can't deal with that.
"gzip" example code:

In QEMU, we currently have:
    max_bytes = 24
the code asks for (3 + 1) doublewords == 32 bytes.

If we write 32 bytes instead of only 24, and return "2 + 1" doublewords
("one less than the number of doulewords needed to contain all of the
 facility bits"), the example code detects a stack corruption.

In my opinion, the code is wrong. However, it seems to work fine on
real machines. So let's limit storing to the minimum of the requested
and the maximum doublewords.
