Subject: [PATCH] server: use longer int in bitshift operation (Coverity)
Message-Id: <1397713098-5813-1-git-send-email-marcus@jet.franken.de>

1195662 Bad bit shift operation

1<<x only does "integers", so 1<<32 and higher will result
in 0. cast to affinity_t instead of using ULL suffix for more
portability.
