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 inventory),
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
Tested-by: Helge Deller <deller@gmx.de> # parisc
Thanks!
