Cover letter [PATCH 0/2] arm64: Fix issues with CPU hotplug and RCU

Hi folks,

Here are a couple of patches following on from:

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
