The patch below does not apply to the 5.15-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to stable@vger.kernel.org.

This is a fix for CONFIG_SMP=n kernels which was caught by testing this explicitly by disabling SMP. IOW, I don't think anyone would be running SMP=n kernels and thus maybe should not backport those...?

Thx.
