Subject: blktrace: use number of configured cpus instead of online cpus
Git-repo: git://git.kernel.dk/blktrace.git
Git-commit: 67313d8f411fe08f3f8a0c94ad2cf45bf569f0f8
Patch-mainline: blktrace-1.1.0
References: bsc#934392

We want to run on all online processors.  However is there is a hole in the
online cpumask this won't happen.  We need the number of configured processors
instead of online.
