Subject[PATCH v3 01/33] radix tree test suite: Fix compilation
Date
From: Matthew Wilcox <mawilcox@microsoft.com>

Patch "lib/radix-tree: Convert to hotplug state machine" breaks the
test suite as it adds a call to cpuhp_setup_state_nocalls() which is
not currently emulated in the test suite. Add it, and delete the
emulation of the old CPU hotplug mechanism.
