MMAP_MIN_ADDR problem/question

[Marek Vasut <marek.vasut@xxxxxxxxx>]

Hi guys,

Me and a coleague of mine recently ran into the issue [1]. The problem is, that 
I set mmap_min_addr to 65536, making it unable for "su - user" command to work, 
it crashes with SIGKILL. I now at least see a solution (set it to 32768). Though 
I don't understand why. Can someone please exaplain me why it has to be 32768 an 
not more?

Thanks in advance!

Best regards,
