I tested your series on the parisc architecture just to make sure that it =
still works
with your patch applied.
On parisc the CPU bringup happens later in the boot process (after the inv=
entory),
so your patch won't have an direct impact anyway.
But at least everything still works, incl. manual CPU enable/disable.

So, you may add

Thanks!
