and the kernel will crash on boot. Because of issues with kexec support,
we are not able to create the tables prior to acpi_table_init().
As a result, we are making a second call to acpi_table_init() to

The SN Altix platform does not conform to the

No need to be calling sn_pci_controller_fixup(), as

this situation. pci_map_rom_copy() allows the kernel to
