[PATCH v3 01/33] radix tree test suite: Fix compilation

[Matthew Wilcox]

From: Matthew Wilcox <mawilcox@xxxxxxxxxxxxx>

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.
