I applied these patches on top of the arm64 for-next/core branch an
tried to run the resulting kernel in a guest (on a Juno platform using
both kvmtool and qemu) with KPROBES_SANITY_TEST enabled. Unfortunately,
the kernel fails to boot with lots of "Unexpected kernel single-step
exception at EL1".

Did you manage to run Kprobes in a guest before?
