Hi,
These patches address a boot failure on arm64 observed when booting a kernel built with the hotplug rwsem changes currently queued in the tip smp/hotplug branch.
I've given these a spin on Juno R1, which now boots happily.
FWIW, I also did a test-merge with the arm64 for-next/core branch, which git was able to figure it out automatically. The result builds cleanly and boots without issue on Juno R1.
Catalin/Will, assuming there are no further gotchas, are you happy for the arm64 patch to go via the tip tree?
Thanks, Mark.
Since v1 [1]: * Fix update_cpu_capabilities() by splitting boot/secondary
