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 avoids including in . Moving struct_efi_setup_data allows to unify duplicated definition of the data structure in a single place. Also silence clang's warnings about GNU extensions in real-mode code, which might occur from the changed includes.
