nano_cpu_idle/nano_cpu_atomic_idle were not ported to the unified kernel, and only the old APIs were available. There was no real impact since, in the unified kernel, only the idle thread should really be doing power management. However, with a single-threaded kernel, these functions can be useful again. The kernel internals now make use of these APIs instead of the legacy ones. Change-Id: Ie8a6396ba378d3ddda27b8dd32fa4711bf53eb36 Signed-off-by: Benjamin Walsh <benjamin.walsh@windriver.com>
