[PATCH v4 0/2] make arm_cpuidle_suspend() a bit more efficient

From: Jisheng Zhang
Date: Wed Jul 06 2016 - 02:21:14 EST


There's one corner case need to be fixed: !cpuidle_ops[cpu].init.
patch1 tries to address this corner case.

patch2 tries to improve arm_cpuidle_suspend() a bit by moving .suspend
check into arm_cpuidle_read_ops().

Since v3:
- rebased on 4.7-rc1

Since v2:
- add back patch1.

Since v1:
- drop patch1, I.E "ARM: cpuidle: fix !cpuidle_ops[cpu].init case
during init", because there may be platforms which doesn't need the
init member at all.
- adopt Daniel's suggestion to move the cpuidle_ops.suspend check to
arm_cpuidle_read_ops().
