This commit comprises the following changes to enable L4Linux to use several CPUs: * change default configuration for x86 and ARM * add atomic cmpxchg operation to l4re library * implement l4_sleep (per thread) * enable setting affinity for VCPUs and IRQs * move "per CPU" section within linker-script (x86 only) * introduce SMP run-script for pandaboard * deactivate direct scheduler (Fiasco.OC syscall) access by L4Linux
