Many drivers include , but do not use boot parameters. Changes to bootparam.h or its included header files could easily trigger a large, unnecessary rebuild of the kernel. Moving struct pci_setup_rom into its own header file avoid including in . Update the only two users of the struct in the x86 PCI code and in the EFI code. Also remove the include statement for x86_init.h, which is unnecessary but pulls in bootparams.h.
