Generic PM domains that support runtime suspend/resume in IRQ safe contexts should define GENPD_FLAG_IRQ_SAFE flag for the genpd. CPUIdle powers off the CPUs in an IRQ safe context and therefore CPU domains that use CPUIlde for runtime suspend/resume would need to operate as IRQ safe domains. Define GENPD_FLAG_IRQ_SAFE for CPU domains. Signed-off-by: Lina Iyer <lina.iyer@linaro.org> --- arch/arm/kernel/domains.c | 1 + 1 file changed, 1 insertion(+)
