idle: Enable interrupts in the weak arch_cpu_idle() implementation
PARISC bootup triggers the warning at kernel/cpu/idle.c:96. That's caused by the weak arch_cpu_idle() implementation, which is provided to avoid that architectures implement idle_poll over and over. The switchover to polling mode happens in the first call of the weak arch_cpu_idle() implementation, but that code fails to reenable interrupts and therefor triggers the warning. Fix this by enabling interrupts in the weak arch_cpu_idle() code. [ tglx: Made the changelog match the patch ] Signed-off-by: NJames Bottomley <JBottomley@Parallels.com> Reviewed-by: NSrivatsa S.
