Reduce built time in some cases by removing unnecessary include statements for <asm/bootparam.h>. Reorganize some header files accordingly. While working on the kernel's boot-up graphics, I noticed that touching include/linux/screen_info.h triggers a complete rebuilt of the kernel on x86. It turns out that the architecture's PCI and EFI headers include <asm/bootparam.h>, which depends on <linux/screen_info.h>. But none of the drivers have any business with boot parameters or the screen_info state. The patchset moves a few limes from pci.h and efi.h into separate header files and then removes the obsolete include statements on x86. I did make allmodconfig make -j28 touch include/linus/screen_info.h time -j28 make to measure the time it takes to rebuild. Results without the patchset are around 20 minutes. real 20m46,705s user 354m29,166s sys 28m27,359s And with the patchset applied it goes down to about a minute. real 0m58,232s user 4m37,617s sys 0m34,993s The test system was an Intel i5-13500.
