ACPI: scheduling in atomic via acpi_evaluate_integer ()
Now I know why I had strange "scheduling in atomic" problems: acpi_evaluate_integer() does malloc(..., irqs_disabled() ? GFP_ATOMIC : GFP_KERNEL)... which is (of course) broken. There's no way to reliably tell if we need GFP_ATOMIC or not from code, this one for example fails to detect spinlocks held. Fortunately, allocation seems small enough to be done on stack.
