linux.git/arch/x86/include/uapi/asm/setup_data.h, branch v6.9 Linux kernel source tree x86/setup: Move UAPI setup structures into setup_data.h 2024-01-30T14:17:06+00:00 Thomas Zimmermann tzimmermann@suse.de 2024-01-12T09:44:36+00:00 efd7def00406ac57400501cdc76d0d95d4691927 The type definition of struct pci_setup_rom in <asm/pci.h> requires struct setup_data from <asm/bootparam.h>. Many drivers include <linux/pci.h>, 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 setup_data and related code into its own header file avoids including <asm/bootparam.h> in <asm/pci.h>. Instead include the new header <asm/screen_data.h> and remove the include statement for x86_init.h, which is unnecessary but pulls in bootparams.h.
