From: Joao Martins <[email protected]>
ARCH_HAS_OPTIMIZED_POLL gates selection of polling while idle in
poll_idle(). Move the configuration option to arch/Kconfig to allow
non-x86 architectures to select it.
Note that ARCH_HAS_OPTIMIZED_POLL should probably be exclusive with
GENERIC_IDLE_POLL_SETUP (which controls the generic polling logic in
cpu_idle_poll()). However, that would remove boot options
(hlt=, nohlt=). So, leave it untouched for now.
