SMP has been available since 3.x if I remember correctly. The 
difference with 5.x is that they are pushing all locks on kernel data 
structures down into the kernel as far as possible. Right now in 4.x, 
there's just 1 lock, and it's around the entire kernel, so only one cpu 
can run the kernel at any 1 time. 5.x will allow different parts of the 
kernel to run on different cpu's.
