Hi folks,
Here are a couple of patches following on from:
https://lore.kernel.org/r/20201105222242.GA8842@willie-the-truck
which address issues when CPU onlining fails but RCU is left none the wiser. Tested under QEMU.
If Paul is happy with the second patch, then I can take both of these via arm64 as fixes for 5.11.
Cheers,
Will
