Hi Thomas,

according to KISSKB http://kisskb.ellerman.id.au/kisskb/compiler/19/
it does, you probably don't need to build allmodconfig.

With this patch I see WARN coming from the kernel/cpu/idle.c:94,
xtensa __platform_idle returns with interrupts enabled.
Interestingly, even the default arch_cpu_idle does so.
