Re: [PATCH 2/3] x86: remove duplicated parser for "pci=noacpi"
so first hunk of the patch doesn't have nothing in common with second , and it is different disable acpi_irqs than disable all acpi, callacpi_disable_pci () is acpi=off. pci=noacpi mean it will not use acpi for pci bus scan and irq routing setting. acpi=noirq mean it will only not use irq routing setting. the problem is that old code in acpi is processing pci= for pci subsystem.
