In addition to the other bits for arm64, we'll need the following patch. Are
you happy to add that to the start of this series?

I've tested this on an arm64 Juno board with a full-fat ftrace config,
CONFIG_PROVE_LOCKING + CONFIG_DEBUG_LOCKDEP, and CONFIG_DEBUG_VIRTUAL=y, and
build tested for 32-bit arm.

Thanks,
Mark.
