Move the following sysctl tables into arch/x86/kernel/setup.c: panic_on_{unrecoverable_nmi,io_nmi}, bootloader_{type,version}, io_delay_type, unknown_nmi_panic, acpi_realmode_flags. Variables moved from include/linux to arch/x86/include/asm because there is no longer need for them outside arch/x86/kernel: acpi_realmode_flags, panic_on_{unrecoverable_nmi,io_nmi}. Include asm/nmi.h in arch/s86/kernel/setup.h in order to bring in panic_on_{io_nmi,unrecovered_nmi} Remove the asm/{nmi.h,io.h} includes from sysctl.c This is part of a greater effort to move ctl tables into their respective subsystems which will reduce the merge conflicts in kerenel/sysctl.c.
