s390/cio: Change I/O instructions from inline to normal functions
Adding tracepoints to inline functions adds tracepoint invocation code for each instance where the function is inlined. The resulting increase in kernel code size can have negative impact: - More cache misses in instruction cache - Reduced amount of DMA-capable memory Therefore change all functions implementing I/O instructions from inline to normal functions.
