commit 894ce5dc825733d1ccab25b1aede9ce0be2a7c4e
Author: Lars Persson <lars.pers...@axis.com>

Fix: do not use CONFIG_HOTPLUG_CPU for the new hotplug API
Kernel configurations without CONFIG_HOTPLUG_CPU throw an unknown
symbol error when attempting to insert the lttng-trace module:
lttng_tracer: Unknown symbol lttng_hp_prepare (err 0)
lttng_tracer: Unknown symbol lttng_hp_online (err 0)
This was caused by lttng-events and lttng-context-perf-counter not
agreeing on which preprocessor condition that should guard the use of
the hotplug API. In fact the API is available also on kernels built
without CONFIG_HOTPLUG_CPU.

I will build a test package and attach here a debdiff.
