[Xen-devel] [PATCH 7/7] x86: cleanup bogus CONFIG_ACPI_PCI uses
We''re building for one case (CONFIG_ACPI_PCI defined) only, yet still
had the other case''s code in there. Additionally there was quite a bit
of pseudo-duplication between disabled(!) DMI scan and ACPI boot code.
acpi_pci_disabled had only a single reader, which is off by default
(i.e. must be enable on the command line), so it seems pointless to
keep it.
