How did you get to 0x4248? I had expected 0x4230.
Not that it matters much, Linux rounds it up to a multiple of PAGE_SIZE anyway.

Gr{oetje,eeting}s,

I guess I probably confused hex and dec values, as the correct
calculation here would have been (4200 + C * 4)
That 4248 value is what you get with (4200 + 12 * 4) so I probably
typed 12 in the calculator instead of C :)
I'll change this even if it does not make any difference..
