Subject: [PATCH v7 03/10] Kconfig: move ARCH_HAS_OPTIMIZED_POLL to arch/Kconfig
From: Joao Martins <joao.m.martins@...cle.com>
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.
