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
