Disabling SMP mode for certain tests was a one-release thing, done to avoid having to triage every test independently (MANY are not SMP-safe), and with the knowledge that it was probably hiding bugs in the kernel. Turn it on pervasively. Tests are treated with a combination of flagging specific cases as "1cpu" where we have short-running tests that can be independently run in an otherwise SMP environment, and via setting CONFIG_MP_NUM_CPUS=1 where that's not possible (which still runs the full SMP kernel config, but with only one CPU available).
