[PATCH 9/9] cpu/idle.c: move to sched/idle.c

Integration of cpuidle with the scheduler requires that the idle loop be closely integrated with the scheduler proper. Moving cpu/idle.c into the sched directory will allow for a smoother integration, and eliminate a subdirectory which contained only one source file. Signed-off-by: Nicolas Pitre

[PATCH 8/9] X86: remove redundant cpuidle_idle_call()

The core idle loop now takes care of it. Signed-off-by: Nicolas Pitre --- arch/x86/kernel/process.c | 5 + 1 file changed, 1 insertion(+), 4 deletions(-) diff --git a/arch/x86/kernel/process.c b/arch/x86/kernel/process.c index 3fb8d95ab8..4505e2a950 100644 --- a/arch/x86/kernel/process.c ++

[PATCH 6/9] PPC: remove redundant cpuidle_idle_call()

The core idle loop now takes care of it. However a few things need checking: - Invocation of cpuidle_idle_call() in pseries_lpar_idle() happened through arch_cpu_idle() and was therefore always preceded by a call to ppc64_runlatch_off(). To preserve this property now that cpuidle_idle_call

[PATCH 4/9] idle: move the cpuidle entry point to the generic idle loop

In order to integrate cpuidle with the scheduler, we must have a better proximity in the core code with what cpuidle is doing and not delegate such interaction to arch code. Architectures implementing arch_cpu_idle() should simply enter a cheap idle mode in the absence of a proper cpuidle driver.

[PATCH 2/9] ARM64: get rid of arch_cpu_idle_prepare()

ARM and ARM64 are the only two architectures implementing arch_cpu_idle_prepare() simply to call local_fiq_enable(). We have secondary_start_kernel() already calling local_fiq_enable() and this is done a second time in arch_cpu_idle_prepare() in that case. And enabling FIQs has nothing to do with

[PATCH 0/9] setting the table for integration of cpuidle with the scheduler

As everyone should know by now, we want to integrate the cpuidle governor with the scheduler for a more efficient idling of CPUs. In order to help the transition, this small patch series moves the existing interaction with cpuidle from architecture code to generic core code. No functional change s
